666.0. "The eagle take to the air" by BZERKR::DUFRESNE (VAXKLR - You make'em, I break'em) Mon Aug 22 1988 13:39

	I will be starting the AQUILLA tonite..I have a target completion
    date of Sept 15. 
    
    For those who migth not be familiar with this aircraft, it is a
    stanard class glider (100"). I have the original all wood kit.
    
    This is my first glider and the biggest (in terms of wing span)
    thing I will have built so far. Pointers welcome.

666.1Build it Right, not fast!USRCV1::BLUMJMon Aug 22 1988 13:5714
    Unless you are one heck of fast builder, you might be putting too
    much pressure on yourself to get this kit done in less than a month.
    The Aquilla, though a mid seventies design, still is a very competitive
    ship in capable hands.  I was just at a contest this weekend and
    Pete Carr(President of National Soaring Society and editor of it's
    magazine) still flys one!  This kit has certainly made the rounds,
    take your time, build it right and you will have a beautiful glider.
    By the way, I heard Airtronics is thinking of offering this kit
    again.
    
    
    Good luck,

666.2fast?? nahh 11 I plan to sweat a lotBZERKR::DUFRESNEVAXKLR - You make'em, I break'emMon Aug 22 1988 14:4010
    I'm not particularly fast.. I just plan to put in a pile of hours
    (3-4 every night). 
    
    I pride myself on being fussy about my building..I plan to be extra
    fussy because gliders must be built just right..
    
    will keep you posted.

666.3Use spoilers/build lightUSRCV1::BLUMJMon Aug 22 1988 16:4812
    Another thing just came to mind.  I do not know what your previous
    glider experience is, but I would recommend putting spoilers on
    this ship.  If you ever plan to enter a contest or do not have a
    huge landing area the spoilers will prove helpful.  My first large
    ship(paragon-118") was built without them and it can be difficult
    to land in a tight field.  Also not knowing your previous building
    projects, it is important with gliders to keep the weight down-go
    easy on the epoxy.  I made this mistake on the Paragon which hurts
    it's calm air soaring ability.

        Re:< Note 666.4 by BZERKR::DUFRESNE "VAXKLR - You make'em, I break'em" >

        Mark,
        
                I got  into  gliders just two weeks ago.  As you probably
        read in the notes file I managed to build it in a week - probably
        about 30 hours -  which  I  wouldn't recommend.  What I wanted to
        tell  you  is  firstly that  I  don't  miss  spoilers.    At  the
        competition the ones that really could  put  spoilers to good use
        had flaps too and extended flaps and  spoilers  at the same time.
        The angle they come down at is really spooky.  The other thing is
        that you will LOVE it.  Saturday I found  my  first  real thermal
        and went up to a couple of thousand feet and  could  have  stayed
        there forever.  I lent someone else the transmitter and he got it
        too  far  down,  so  the flight ended after just over 10 minutes.
        The Metric really flies extremely well.
        
        Go for it.

666.6ThoughtsAKOV11::KAUFMANNTue Aug 23 1988 12:144
    I've considered spoilers in my next glider, but give some thought
    to a take-down wing (collapsable wing ???) whatever. My glider spans
    78 inches and I have a hard time fitting it in the car. Good luck.
    
666.7Day 1BZERKR::DUFRESNEVAXKLR - You make'em, I break'emTue Aug 23 1988 13:4917
    worked about 3.5 hrs last night..Kitted the stab and got one side
    half assembled. This is dainty work guys.. The worse part is going
    to be the fuse with all its compound curves. MAybe I should hold
    a sanding party..
    
    Note about the kit: This is a first class kit. all parts cut (no
    punch outs).. Includes all hardware. One thing I will not use is
    the NYRODs. Will use piano wire instead. Will also install spoilers.
    
    Plans detail an optional thermall sniffer.. I think I will bypass
    that.. I've read that one can buy these widgets that will sense
    thermal and feed input to the rudder. That way the pilot have visual
    notification that the plane is in a climb.. Anyone got any comments
    one these??

    MD-
    It's about time you started that beast!  It is a beautifully kitted
    plane, isn't it?  (I'm kinda sory I sold it, now :^} )
    
    I think that the rudder/thermal sniffer is kind of hokey, it might
    be difficult in knowing if the turn is trim or windvaning or thermal
    sniffer related.  Better you should watch the wings for turbulence/
    lift indication and FLY LIKE A MAN!!  (That's _like a person_ for
    Dianne!)   :^)  :^)

666.9Another kind of snifferMURPHY::ANKERAnker Berg-SonneTue Aug 23 1988 14:3918
        Re:< Note 666.8 by MJBOOT::BENSON "__Frank Benson, DTN 348-2244__" >

                The thermal  sniffers  I know of don't affect any control
        surfaces, but send  a  signal  to  a receiver on the ground.  The
        normal signal is a  tome that goes up in pitch when the sailplane
        is rising and goes down  when in a downdraft.  This leaves you in
        complete control of the plane.

666.10Right! But...MJBOOT::BENSON__Frank Benson, DTN 348-2244__Tue Aug 23 1988 16:3310
    Anker-
    The transmitter type of sniffer is what's shown on the Aquilla plans;
    those are the only kind I'd consider.  Lately, however, I've seen
    ads for a type that doen't transmit... when it senses lift it feed
    right rudder to let you know; those would make me nervous!

666.11I Miss SpoilersUSRCV1::BLUMJWed Aug 24 1988 12:5413
    Regarding Anker's comment about not missing spoilers, I can understand
    that when flying a 2-meter ship(ie like his Metrick).  The smaller
    span, lighter wing loading ships slow up nicely when brought into
    the wind, however the larger span ships are much more difficult
    to bring down in a reasonable area at a reasonable speed without
    spoilers.  As the wing loading rises, so does the speed and the
    ship seems to glide forever when you want to land.  The spoilers
    allow you to bleed off a lot of altitude quickly without dropping
    the nose and raising the airspeed.  I would not build a standard
    class or larger ship without them, unless it was a fun fly ship
    only and I hade a large field to land in.

    The stab assembly is complete. The rudder also. Need to shape &
    sand both.  Tonite we start the fuselage..

666.13day 3BZERKR::DUFRESNEVAXKLR - You make'em, I break'emThu Aug 25 1988 13:2317
    Started work on the Fuselage.. This is not a slap'em together, sand
    a bit & cover affair. No Sir !!. There are fairings all over the
    place. And I won't even begin to tell about all the sanding i'm
    going to have to do. Bootom line: This is one very sophisticated
    flying machine..
    
    I got the sides done (add triangle stock, mark for formers) Then
    worked on the tail fin & rudder attachment. This a critical part
    as the stab is a single piece and therfore the play must be just
    right. I also have to make its square, otherwise the whole tailplane
    will be out of whack..
    
    Today I go out to get myself some glue & microballoons.. Also ne
    fuel for the CUB..

666.14day 4BZERKR::DUFRESNEVAXKLR - You make'em, I break'emFri Aug 26 1988 14:3115
    Last nite was a slow one. Started by finishing the tail fin.. That required
    epoxxy and making sure everything was lined up & square. Otherwise
    things will real intersting when the fin is taatached to the fuse
    and then the stab & rudder attached to all this..
    
    Started fuse assembly. Attached fuse end (again epoxy so that I
    could line things up.. Now with all my clamps iin use, I had to
    wait a while.. So I trimmed the top fuse sheet and then sanded one
    stab panel..spenn an hour on just that..came out real nice.. Need
    a little filler where I gouged a bit.

    This weekend is going a biggie: fuse assembly..Maybe start on wings.

666.15days 5-6-7BZERKR::DUFRESNEVAXKLR - You make'em, I break'emMon Aug 29 1988 13:3225
    The weekend was a bit slow..household chores sorta got in the way..
    
    Anyway. I got the fuse boxed. It's as long as the one on my CUB.
    Its also a lot skinnier. It came out right on the money as far as
    lateral dimensions are concerned. The only prblem I have is a slight
    twist..The instructions say that this is normal and correctable
    when installing the fuse bottom. 
    
    I also install the rudder pushrod.. So now I'm ready to install
    the tail fin.. This one is a bit tricky.. first you need your stab
    & rudder 'cause you're going to put on the stab fairings. You also
    are going to position the rudder. everything has to be square relative
    to the fin (the instructione mention something about longitudanal
    decalage.. That's the side to side stuff, right ??)
    So I had to final sand the other stab half and the rudder. Tonite
    I put the pieces together.
    
    I'm going to have to build the wings next because at the point you
    have to put the wings in to make that the tail assembly is square
    with the wings (ie take out the twist)..

666.16SPELLING-BEE....??PNO::CASEYATHE DESERT RAT (I-RC-AV8)Mon Aug 29 1988 14:4715
    Marc,
    
    Correct!  Longitudinal decolage* translates to built-in (desired)
    offset in the vertical stab (fin) and/or, in the case of a power-plane,
    right of left engine thrust.    
    
    *  BTW, can anyone provide the correct spelling for "decolage?"  My
    Funk and Wagnalls doesn't contain the word and I've seen it spelled
    so many different ways I'm really curious...gracias in advance.

    Thanx, Marc,
    
    "Decalage" is how I used to spell it 'til I saw it spelled dec"o"lage
    in an aviation publication.  That's when I tried, unsuccessfully,
    to verify the correct spelling.  Goes to show that the mag.'s aren't
    always correct either.

666.19day 8BZERKR::DUFRESNEVAXKLR - You make'em, I break'emTue Aug 30 1988 13:2428
    last nite was diddle night. I finished sanding the rudder. That
    was the easy part. I then proceeded to install it..Weelll, let me
    tell you, this was fun..
    
    First some background. The rudder is designed to be removable. Two
    hinges are inserted in the tail fin. an other in the rudder. There
    also a 1/8" OD tube in the rudder rib just above the fin. You line
    everything and insert a 3/32" hinge pin. Aah,.. easier said than
    done.
    
    I positioned the brass tube per plan and discover that this would
    require a 3/32" gap on the rudder hinge in order to make fit.
    (the hinges on the tail fin are flush against the rudder post. So
    I had to shift the tube back (enlarge hole, shim,etc) so that
    everything is just right...
    
    Of course, as you got through this exercise, you have to make sure
    the lateral alignment over the fin is correct, that the rudder clear
    the top of the fin and that the vertical alignment is also what
    is supposed to be..
    
    I quit after two hours 'cause I couldn't see straight anymore..
    I think I still have to do some work on the vertical alignement..
    
    md
    
    
    
666.20SPKALI::THOMASTue Aug 30 1988 14:229
    An easier was is to employ a tape hinge on the rudder. For this
    you bevel the rudder's leading edge all to one side like a barn
    door aileron. After the vertical fin and the rudder are covered
    you align the rudder to the fin and deflect the rudder. Run a strip
    of tape on the outside and then deflect the rudder in the opposite
    direction and add a second piecr of tape to the inside of the hinge
    joint. Any vinyl tape can be use.

666.22day 9BZERKR::DUFRESNEVAXKLR - You make'em, I break'emWed Aug 31 1988 13:3233
    re .-1: Naah.. Thats refered to as vertical decalage..and everybody knows
    about that one...
    
    Anyways, onwards with the daily report..
    
    I had an other look at the rudder (with rested brain cells) and
    noted that the "kink" in the rudder assembly was actually to the
    the fin being twisted. SInce the fin is made of plywood sheet on
    a frame of basla & spruce, I was a bit suprise.. So out with
    the knife, unglue on side, shift a tad (like 1/32"), reglue aand
    voila, one straigth rudder assembly..
    
    I had to set aside the fuse in order to build the wings..They are
    needed to ensure that all surface are square relatie to each other..
    
    So, I cut the sheeting for wings.. there are 7 sheets of 1/16th
    stuff to cut to various shapes. fine.. nice relaxing work..
    Now to start the wing assembly...Get trailing edge...Hellllo, what
    is this?? TE is a built affair made of 2 1/16th sheet separateg
    by a 1/4 by 1/16th strip.. but wait, there is more. The bottom
    part of the TE must beveled to zilch on the last 3/8th" to form
    the airfoil...yeah sure...do that for 100" of strips.. Arumph
    Ok so I sanded (by hand, guys, by hand!!) for more than an hour
    and fgot the inner panel TE done. The outer panels I'll attend later.
    I have to build the inner panel and ouoter pannel separately because
    my work area is limited..
    
    QUit at 12:30 'cause the next step is to start assembly.. I need
    a rested mind for that. This wing assembly make the CUB's setup
    look like a picnic..

    Started on the wing...Got the inner panel of one wing ribbed & sparred.
    The other inner panel has LE, TE and capstrips in place..
    
    The next major step calls for putting a mixture of epoxy & microballons
    between spars at root ribs to fix hold down tubes in place..There
    is not mention of proportions.. I plan to use a 50-50 mix..

666.25days 12-15BZERKR::DUFRESNEVAXKLR - You make'em, I break'emTue Sep 06 1988 13:3336
    An other slow weekend..I got started on the second inner panel
    (capstrips & bottom spar glued when I notice a couple of things
    didn't look right (like the spar was 1/16th off on the plan - now
    I _know_ I measured the sucker just right. And the ply shear web
    that sits near the wing root was also of by the same amount..)
    Then I remembered about the the root rib being a ply rib..And that
    the plan for the second wing probably was drawn to show it in place
    (the first one does not)..So I lift the wing of the plan, and sure
    enough.. the whole thing is offset to show the ply rib.. 
    
    Grumble, arumph.. dismantle the capstrips, re-pin the wing correctly
    and proceed on..   
    
    Took Saturday off..
    
    Sunday, started on outer panels. spent the better part of the evening
    cutting TE pieces to shape & sanding. Started on 1st outer panel..
    
    Last night, watched PLATOON on HBO (Messy movie that !!)..Finisehd
    outer panel and got far enough on the last one to be at point where
    I glue ribs & spars.
    
    Tonite, the fun begins. I get to glue wing hold down tube in place.
    The we go on to gluieng the panels together with proper Dihedral.
    
    
    BTW, does anyone know what "sanding hand-laucng glider style" means??
    (In context here, when I get to the point where I have to sand the
    ends (LE, TE & spars) of the inboard & outboard panels so they butt
    properly, the instructions say to raise one end a certain amount  and 
    then "sand the other "hand-launch glider style".

666.26day 16BZERKR::DUFRESNEVAXKLR - You make'em, I break'emWed Sep 07 1988 14:4229
    I ran into a stone wall amd I'm not pleased. In fact, I'm rather
    p****d off !!.. So last night, Im going to finish the last outer
    wing panel(hey, real easy, just add ribs, spar & webs). Well I now
    have this little problem: The last spruce spar in the kit ain't
    what it's supposed to be..It's a 1/4" x 3/16"... it's suppoed to
    be 1/4" by 1/8". Now there is one other place in the kit where I've
    used this kind of wood and its in the fuse as a doubler. Check this
    instructions, check the plan.. It sez use 1/4 x 1/8..So no mistake
    there... I guess I have to go out and buy me a spar.. (i was temptd
    to build me one fromt the left overs.. with the shear webs in place
    its probaly not going to be a problem.
    
    Ok, so pass on the outer panel.. Go and install wing joiner tubes..get
    1/4" OD brass tube. That goes into wing...drill trough W1 .. fine..
    Now get 7/32" joiner...I must presume this a steel rod. (all the
    joiners are). I looked high & I looked low. I looked over and I looked 
    under.. I looked far and I looked close. Nada.. Nixt... A steel rod 
    this big and about 8"" long just does disappear that easily.. 
    
    Now anyone got suggestions on where I can get such a piece..
    
    Ass it stand, I can't do much more as the joiner is needed to allign
    the tubes. Then I need to finish the wing in order to finish aligning
    the tail feathers..
    
    grumble. grumble. grumble

666.27ARE YOU SURE IT'S _SUPPOSED_ TO COME IN THE KIT...??PNO::CASEYATHE DESERT RAT (I-RC-AV8)Wed Sep 07 1988 15:4212
    Marc,
    
    Is there some reason why you _can't_ use a piece of 7/32 music wire?
    It'd certainly be more than strong enough!  Is it possible the kit
    intends for a piece of wire to be used and does _not_ include it in
    the kit??  Just a thought..................

    well, all the other joiners are in the kit. I would expect this
    one to be there also..
    
    Music wire ??? Are you sure your piano isn't designed to be played
    by elephants.. This "wire" is almost 1/4" in diameter. That's gonna
    a take a lot of hammering to get going !!
666.29SHOULD BE NO TRICK AT ALL.....PNO::CASEYATHE DESERT RAT (I-RC-AV8)Wed Sep 07 1988 22:1518
    Marc,
    
    You bet!  Piano/music wire'd work just fine, provided it doesn'
    require any exotic bending...I'm assuming the joiner is basically
    a straight piece, perhaps with a slight bend to allow for dihedral.
    
    Size is no particular problem; consider that yer' average landing
    gear wire is 5/32: and the giant-scale guys frequently use 1/4"
    and _bigger_.  7/32" is right in the middle somewhere and shouldn't
    be difficult to find...I could go down to the local hobby emporium
    and buy it right off the rack.  You'll have to use a cut-off wheel
    (like that made by Tuff-Grind) in a Dremel-tool to cut it though.

    re .-1: Ok, I'll look it up.. The comment was made to me to make
    sure the stuff was tempered, otherwise it will bend..
    
    The piece I need is straight. Dihedral is taken care of by angling
    the hold-down tube in the wing from top to bottom spar and epoxiing
    them in place.
    
    BTW, did nothing last night.. too depressed !!

    Marc,
    
    I'm not sure that music wire isn't _already_ tempered.  In any event,
    I can't begin to imagine a piece of that size bending under normal
    flight loads...if it means anything, _I'd_ sure trust it!

    MARC,
    
    I'll bet the other joiners in the kit are nothing but music wire;
    what'll ya' bet?
    
    BTW, how far does the joiner in question project from the side of
    the fuselage?  It'd hafta' be _plenty_ long before there'd be any
    potential for bending.  If we're talking simply about short stubs,
    about 3-4" or so long, I can't imagine enough flight load to bend
    them; Hell, my scale oleo-struts on the MiG-3 are connected to the
    retract units by being set-screwed to a 3/16" music/piano wire stub
    and, despite being pranged pretty good a number of times, these
    wire subs have _never_ even tried to bend!

666.34Heat Treating Wing RodsUSRCV1::BLUMJThu Sep 08 1988 19:5017
    Although I tend to agree with Al, "How the hell could 7/32" music
    wire bend without the wing ripping off", let me relay some info.
    I read in a review of Ken Bates Merlin Glider carried in a 1980
    edition of Model Aviation Magazine.  The Merlyn(designed by Ken
    Bates who is avery successful contest flyer and LSF level 5 pilot)
    requires heat treated wing rods.  Ken is so emphatic about this
    requirement that he actually sold them for $5.00.  For those not
    familiar with the Merlyn, it is a 155" wingspan with 2100 sq. inches
    of surface area.  The finished ship ways approx. 10lbs. and is capable
    of speeds in excess of 90MPH.  Considering Ken's background and
    achievements I would tend to trust his judgement.  However, the
    Aquilla is a much lighter ship and probably would not require heat
    treating.

    a piece about a foot long and go for it..

    Spent the weekend working on the wings. Talk about detail work..
    
    first I set the joiner tubes with a mixture of expoxy & micro-ballons..
    This mixture turn to the consistency of chewing gum.. Makes for
    intersting results..
    
    Then fit the outer panel dihedral set (right wing) and glued the
    pieces together. This time (unlike my experience with the CUB, I
    made sure everything was pined and straight..

    Wath with the ply joiners, the capstrips and the sheeting, I spent
    the better part of 4.5 hrs doing the one wing..
    
    the second wing is in position and ready to get the same treatment
    tonite.
    
    Tere is a glider fun fly this week-end.. I'm going to try to make
    it.. at this time it looks real tight.. The fuse requires a major
    sanding job..

    finished the other wing last night..
    
    Now the fun begins: sanding & gouging. we start with the wing tips..The
    AQUILLA as tips known as Hoerner tips (They flare up and cheat the
    wung in thinking its actually longer than reality..). So you get
    a block of wood, a scoop knife, left over core from MONOKOTE,
    sandpaper and patience and go at it..
    
    Oh yeah, there is also this mention to make the LE progressilvely
    blunter along the outer wing panel in order to avoid/reduce tip stalling.

    Now lemme see, tonite & tomorow on the wings. Thursday & Friday
    on fuse... Saturday we cover...Its a long shot for the fun fly..

The AMA rules (which I have but have not read) have been quoted to me
several times.  10 minute precision is what we call thermal duration.
Usually 1 point is earned per second up to 10 minutes in this case. 
After that 1 point is lost per second until the landing.  The AMA rule
on the landing stop time is the moment of first contact of the craft
with anything other than air or another craft.  In other words ground or
trees.  The AMA rule on start time is the instance it drops off the
winch.  There is usually a bonus score awarded for landings.  Usually at
CMRCM they have a graduated tape that starts at 100 points for perfect
landings and a mark every 2 or 3 inches with a decreased score.  The AMA
rule is that the landing is worth 0 if the craft flips over of sheds any
parts.  They are trying to prevent Anker from dropping an anchor at the 
landing target and also they want the landing to be realistic so wings
and canopies should not fall off.

>I'm apprehensive about entering since they probably will be using a winch, which
>I've never used before, and considering Kays' wing-folding experience, I'm not

Go for it.  I never harmed a glider on a winch unless I was greedy. 
Ask an expert to launch it for you the first few times.  Al you have to
do is steer and he will run the winch for you.  They have always allowed
this in contests - don't know what the AMA says about it though.  In N.Y.
there was a guy competing from a wheel chair so naturally somebody else
ran the winch for him.  I personally never had anyone else do the winch
cause I wanted max exposure since I only get to use one at contests.

Disclaimer - above rules are based on my experience and listening to
other glider guiders at contests.  The rules for launch and landings are
also specified by the LSF in another note.  I have read and understand
them and they are as listed above.  At pilots meetings just before the
first launch we always ask questions like what is the rule on

POP offs?
Tree landings?
Declaring landing zone targets?
etc.

For instance at some contests POP offs count unless in the opinion
of the winch operator or CD it was caused by faulty equipment.  At some
contests you are allowed a fixed number (3) pop offs.  At my last
contest you could have all the pop offs you wanted?  So what is a pop
off you ask?  That is when the winch (or high start) pops off the tow
hook way before you want - typically 30-50 feet out.  Usually it is
caused by greed - too much up elevator.  You can also cause it by
too long a pause between pulsing the winch foot switch thereby causing
slack in the line.  Equipment can cause it by line breaks or if there
is a parachute on the line it could open and you over fly it if it is
very windy and you have a lot of down elevator,  retrieval lines can
pull it off if they are snagging on the ground, etc.

The tree landing issue came us because we had so many tree landings at
the CRRC meet.  The rule there was you got a zero for the flight time
if you landed in a tree.  Sort of infinite penalty points because you
went over time and haven't landed yet.  The rule on the last contest
was if you could see the plane the time stopped when you hit the tree
(landed).

In the New York contest they had two close landing zones and you had
to declare which one was your target.  One guy over shot and made a 
great landing at the wrong target.  Half of us thought he should get
the landing - the CD said NO.  At the last contest they also had
two landing zones and allowed you to declare seconds before touchdown.
The wind sort of helped us decide where to land.

Go for the contest Dave - you'll love it.  

In case anybody saw it but didn't make the connection - Dave's glider
was at the last fun fly.  It was the Sophisticated Lady with the authentic
American Indian design Ultracote job in tan and brown - beautifully done.

Remember - this is for CMRCM members only as per note .40
I'm sure they welcome spectators.

It would be at the same location as the DECRCM fun fly.

Most events start around 9:00-10:00 AM so 9:00 is a safe time to
arrive for nearly anything you are not sure about.

    re .-2 or so about spoilers..There will be spoilers, per plan. Which
    means its a preformed TE piece set so that it flush with top of wing.
    They are pull up type with a weight to pull them back in place.

    tips done last night..It's amazing how damage 50 grit sandpaper
    will do to basla.... Also it was a lot easier to carve the tips...

    Turns out that setting spoilers in their bay took a lot longer than

    OKOKOKOK.. So I've Been out for a while. Work has been crazy. Home has
    been crazy and money has been tight.
    
    Anyway, I have progress to report. I left off this tale where the fuse
    was just about complete and ready to get sanded.
    
    Threee week ago, I pick things up again. Got the fuse sanded. FUN!!
    Dust all over the place. Sucker came out looking pretty good. Was a
    lot easier than anticipated. Nice curves ! 
    
    Built & fitted canopy. Snug as a glove. 
    
    Then came the moment of truth. Covering. To paint or to MONOKOTE. The
    book suggested the fuse be spray painted 'cause of the curves.
    Well I don't have equipment. I don't have the space. And I'm a complete 
    klutz with a spayer. MY consultant sez use a brush.. HUmmmm. Maybe. 
    He also sez: I can over this cover this sucker with two pieces of monokote.
    I have 4 rolls of the stuff (came with the kit). SOLD.
    
    WELLLLLLL. This was fun and a lot easier. MONOKOTE will stretch ever
    which way. Two evenings & I'm done. 
    
    Wings & tail feather a breeze.
    
    Fit everything together. Tail is square. Wings in line with tail.
    A little heavy on the right. No big deal.
    
    Spent weekend fitting electronics. Had to gut the CUB. Talk about tight 
    fit. The servos are a little deep and a little wide. Trim mounting rails. 
    YUK.. Everything OK.. Front servo is just even with canopy edge. Had
    to trim canopy floor for fit. Fortunately, I have 1/8" to play with.
    
    Onto spoiler adjustement and balancing this week. 
    
    I have to repackage battery pack. Its a flat style. Has to be square
    style. I plan to clip a tab, solder a wire in its place and fold the
    batteries together. 
    
    Maiden flight sometime this week, weather permitting.
    
    All in all, this is a fun plane to build. Learned a lot and the results
    look pretty good so far. I hope the plane flies as good as it looks.
    
    Now for an encore, I think I will try an ORCA (Model Aviation, October
    89 - or is it November). Same base technology with a few (sic) twists.

    Went out Saturday. A bit breezy. found servos reversed. fix using
    switch in Tx. 
    
    A few tosses to check attitude. best way to describe flight is
    "majestic". All ok so hook up on hi-start.
    
    Tow up is just fine. release. Aquila then gave a real runn for the
    money, porpoising like crazy. Also found difficult to turn.
    
    FInnaly got it under control and back on the ground in one piece.
    
    Discovered pushrods were flexing and not providing control needed. Take
    home & adjust.
    
    Switched to Gentle Lady. Got a couple of more fligths in and called a
    day (geting cold). will try again this week.

    Went out yesterday aft. Perfect day to fly & trim out the glider.
    little or no wind. Bright sunshine. About 70 deg.  
    
    Did a couple of hand tosses to check for gross imbalances. Couln't find
    anything.. SO we hitched the sucker on the hi-start and let let rip.
    
    Up staight as a arrow. very stable. Off the hook and check for trim.
    Weellll. It turns out we needed nothing. a case of "it flies right of
    the box". Very nice.
    
    So  Ispent the next few hours going up & coming down Longest flight was
    about 5 mins. Not bad, considering this was really the first time i've
    flown solo. 
    
    Weekend looks promissing..
