958.0. "Charlie Chaplin flies gliders; clowns 11, Cullen 0" by ESASE::CULLEN () Wed Apr 12 1989 14:36

    Hi,
    
    Well I thought that I  would start a  note specifically for all those
    Glider ONLY aerial manoeuvres  that people do. The  other note on
    aerial manoeuvres doesn't cover the silent  flight birds. I will let
    someone else  kick it off since I am not flying gliders for all that long.

    Regards,

    I haven't flown gliders since 85 but making a 5 miunte max in 
    3 minute air is quite a maneuaver.

958.2Short duration "technique"NEXUS::PAGEWed Apr 12 1989 15:0218
    
    	Here's one. Launch into lift on a strong club winch. then just
    when you do the zoom, explode one wing and autorotate down using
    full rudder to one side. I did it in our last contest and got a
    real roar from the crowd. It landed from about 5-600 feet and did
    little damage to the rest of the plane but was it ever a sight coming
    down like an Elm tree seed?? OH! and I got 26 seconds for the flight,
    so one those tight multi round duration add-um-ups this can be a
    real "technique" 
    
    	Cant get much on landing points though??!!
                                    
    	Ill see if we cant come up with some real stuff for you!!

958.4Speed is funUSRCV1::BLUMJThu Apr 13 1989 14:5819
    This is a simple, but fun maneuver that can be done any number of
    times when slope soaring, but only once on level ground before a
    relaunch.  When I get bored of "sensible" slope soaring, I get
    my Sagitta 600 up to about 300 ft. and put it in a steep dive,
    leveling out at about 20 ft.  The whistle of laminar airflow over
    the wing as the ship comes by in excess of 50 mph is something to
    behold.  You simply turn out into the lift on the slope and are
    free to do it again!  Larger ships can execute this move in excess
    of 100mph.  At these speeds the full flying stab is super sensitive,
    and care must be taken not to stress the structure to the breaking
    point.  The world slope soaring speed record is 247 mph, established
    in Switzerland by placing a low drag slope soarer in a vertical
    dive.  I have seen films of German factory flyers(ie Multiplex,
    Graupner)  bring their gliders over the field doing slow rolls
    and high speed, low level inverted flight.
    
    Regards,

958.5No problem!!!!!RVAX::SMITHThu Apr 13 1989 16:5011
    RE: .3
    
    	As soon as I popped off the winch, I'd let whatever airspeed
    I had just about run out, then kick in hard left rudder and do a
    hammer head. Dive for 15 of the 20 feet and apply enough up elevator to
    recover but keep the wings just below the snap point. As the glider
    came by me, I'd snatch it out of the air, and do it right the next
    time. Who says I don't have an imagination!!!!!!!!!!

958.6Try for this kind of precision landing !LEDS::COHENThu Apr 13 1989 17:3820
    You could do what I did at our last summer's fun fly in Westboro.

    Take one Wristocrat HLG with a poorly functioning Stabilator, stand in
    the middle of the field, make sure everyone's watching (except Dave
    Hughes, who's got to be flying at the time).  Launch the glider at about
    a 80^ angle, as hard as you can (this is good for about 50-60 feet of
    air).  Try and feed in some down elevator (which will have no effect).
    Try and feed in some up elevator (which will have no effect).  Wait till
    the plane stops moving, stalls, and flips over so that it's pointing
    straight at the ground (step aside a little, it's also pointing straight
    at you).  Feed in *ALL* the up elevator you can (which will have no
    effect), bending the elevator control stick in the process, if you can.
    Watch the plane burn straight in.  If the nose is tapered properly, and
    the ground is soft enough, the plane will bury nose first to a depth of
    about 1.5 inches, stick straight out of the ground, and quiver like a
    spear thrown into a tree.  On a timed duration event, you'de not get
    many points for flight time, but you should get extra bonus points for
    precision landing.

    P.S.  The plane was COMPLETELY undamaged.  It still flies like SH*T.
958.7Here's a coupleCURIE::ANKERAnker Berg-SonneThu Apr 13 1989 18:0523
                Here is a simple, but spectacular manouver.
        
                Put the  glider  on  a good, strong hi-start or ideally a
        winch at a  competition,  and  then launch it without turning the
        receiver on.  What  you  get  is a gradual slide to one side that
        either ends with a pop-off  or a powered descent into the ground.
        It works best with lots of spectators.
        
                There is another one.  Land  it  in  a field covered with
        people  moving  around  -  crowds  are  best    -    and  various
        paraphernalia scattered around.  When you are really good you can
        prevent it from hitting anybody by using a chair as a brake.

958.8Haa Haa!!!!CSC32::M_ANTRYFri Apr 14 1989 12:2533
    Boy...Who started this note??????
    
    I have to say one of the funnier blunder I seen involved a fellow
    noter, Bob Page.  Now this was last year when Bob was young and
    budding.
    
    Bob had a 100" Riser and a 2m ship.  Well he must have been working
    on the 2m the night before putting in the radio.  Anyway to get
    his thumbs wet before the maiden voyage on the 2m he launches the
    Riser.  Hey......Hey......Woah....He yells......something is wrong....
    He pops off early and manages to put it on the ground in one piece.
    He walks over and looks and says.....Whoops I reversed one of the
    servos while I was installing the radio in my 2m last night. (The
    rudder) No problem I will throw the switch on the TX and all will
    be right, Yes its working just fine now.  Ok that plane flies Ok
    I will now fly the 2m.  Up the launch it goes.
    Hey......Hey......Woah...(You can guess what happened!!!!!!) The
    plane wasnt damaged, But we did chuckle over that one.
    
    For a real good power trick applied to Gliders, try flying a poly
    headral plane inverted.  Now that is a trick!!!!!!!
    
    A ailieron, straight winged plane lick the one I am flying at the
    slope this weekend (Bob Martin TALON) is a lot of fun on the slope.
    It is just as acrobatic as the avg power ship and its so fun because
    the speed has to be managed alot more with no prop on the front!
    
    I know a perfect way to keep us sailplane flyers from launching
    with the radio turned off,  Put a throttle on'em!!!! Yuk Yuk
    
    
    Sorry Bob, I just had to mention that little blunder of yours.
    
958.9are we getting anywhere ?ESASE::CULLENFri Apr 14 1989 13:046
    >Boy...Who started this note??????
    
    Yea.... I am beginning to think that it should have a slightly different
    title based on the replies so far...'Charlie Chaplin Flys Gliders'.

958.11Yes, but Ron Forgot the other close call!!!CSC32::M_ANTRYSat Apr 22 1989 22:3921
    Ron forgot to mention that on the way back we had another close
    call.  Me and my 5 year old daughter rode out with ron and on the
    way back as we were discussing his pantera manuever we are coming
    up on small airport that is out east of town.  We were all looking
    at some planes that were getting ready to take off as we were passing
    the end of the runway.  You know one of those fields where the rode
    at the end of the runway is withing spitting distance from the end
    of the runway.  Anyway as we go by Ron and I are looking at the
    airplanes when my daughter lets out this squeel and says that plane
    is awfully close.  I looked up and seen just a pair of wheels go
    by the windshield.  How close were they you ask??????? The tires
    were 5.25"x10.5" goodyears with 6 plys and a max inflation of 75
    pounds.  Does that tell you how close.  Another club member driving
    behind us stopped and said Oh yeh, the plane cleared you by at least
    a foot or more.
    
    So as you can see.  Ron had 2 close calls today, both were only
    off about a foot!!!!!
    
    I'll drive next time Ron OK!!!!!
