I have just finished building the SIG KAVELIER and it flies
great except for one thing.That is on take off's it has what I
call "TAIL DRAG" meaning that the tail drags that's the only
explanation I can thing of.Anyway after it levels off it will
fly great I can loop,emblems,snap roll,etc...
I've got an O.S. 40 in it,and I had a couple of suggestions
as too use a 10-6 prop instead of a 10-5.The other one was to put
some other kind of muffler I can't think of the name of it right
now,but I haven't flown in a couple of week's and I think I'm
going to try a new prop.I'm wondering if thier are any other
suggestions out there.
KEEP'EM FLYING

Jerry, What do you mean by "Tail Drag". Are you saying that the
tail drags on takeoff, or are you saying that the tail appears
low while the plane is in flight?
I think you mean the low tail during flight. This is not good.
Check your incidence angles and ballance points. Check the balance
with the fuel tank empty.
If you mean the tail drags on takeoff then increase your speed down
the runway and duration of the plane traveling down the runway prior
to rotating for takeoff. Also if possible use a shallow angle of
attack during takeoff.
In a pattern contest a "10" takeoff is one that starts from an ROG
then has a smooth throttle increase. The wheels break ground in
front of the pilot and the angle of rise in the plane is such that
the plane is only six feet off of the desk at a distance equal to
the takeoff roll.

I think your ground speed may be too low when you're taking off.
I have a Kavalier that I just put into service this spring. I think
it's a great plane. I have an OS 45 FSR (more powerful than yours)
and the thing I like best about the Kavalier is the smooth takeoffs.
I'm using a 10-6.5 prop. I definitely think you should go to the
10-6.
If you're flying off a grass field, you might try larger wheels.
I'm using 3" on the main and 2-3/4" on the nose. It rolls very
nicely, with very little tendency to wander on high-speed rolls.
The Kavalier has adequate wash-out in the wings and that's
why you haven't had more trouble in taking off at low speed - its
low speed performance is superb. A friend with a Trainer 40 had
lots of trouble with snap-rolls immediately after takeoffs due to
too low a takeoff speed, and larger wheels helped him.
My Kavalier rolls nicely to high ground speed, then rotates smoothly
on the main gear, rolls a short distance further, and then lifts
gracefully. Of course, I have enough engine that I can just gun
it and leap it off the ground, but that's not as pretty. Once in
flight, I cut the throttle back to half to three-quarters for most
of my flying.
Good luck!

I'M BACK
I went to a bigger prop 10-6 and check balance and the other
problem I had was on take off I was giving it too much elevator.
I was trying to get it as far away from the ground as quick and
as far as possible before something happened.I've been out flying
several times since I started this note and I'm flying closer to
the ground and have gotten over the fear of high speed dive bomb
runs.The SIG KAVELIER is a great airplane in my opinion.
KEEP'EM FLYING
