| Subject: | Re: : Kolb-List:Stabilizer Angle |
Just finished a 30 minute test flight. Aircraft improved by both the tape seal
on the aileron gap and the trim tabs on elevator. Hands off at 40 mph at 4750-4800
rpm. 48-50 mph at 5300-5400 rpm with very light forward pressure on stick.
Rudder trim for some reason was better than last flight even with no change.
Still need a small additional bend in rudder trim tab. This flight was still
WITH the raised stabilizer angle, but with the addition of the elevator trim
tab.

Sounds like youre making some positive progress,Bill. Those aileron gap seals make
a big difference. Both in speed and handling.

If it was me, I'd experiment with the horz stab in the normal position and go to
larger elevator trim tabs and play with the angle of the tab.

I believe that I mentioned before that without an adjustable trim tab, your
only option is to trim for what you consider "cruise" RPM's. Mine is 5400.
That gives me the most speed for the least amount of gas expended. When I
increase the RPM's it begins to climb, which is the proper function of
power anyway.
I went over to the ranch to check for stuck cows in the pothole field, and
I was in a hurry, so I was turning around 5800 (max continued power) and of
course the plane was climbing at about 300 fpm and I had to use a lot of
forward pressure on the stick to try to keep at the altitude that I wanted
to fly. It came to mind that this could possibly be what you are talking
about as a problem? I had never paid attention before because it is just
the way that Kolbs fly. Is it possible that you are expecting your kolb to
fly like a 172, cause it "ain't gonna happen". In essence it could be
possible that some of the things that are worrying you, could just be the
normal reaction of the aircraft that you are flying. Now I know that you
might be a bit delicate, but none of this is intended to insult you.

When get your weights it might not be a bad idea to pick two different datum's
and run the numbers as a check. The CG should be the same.

Just thinking about elevator trim tabs - I have a small one on my MKIII because
when I first flew it there was was one speed and throttle setting where it wanted
to do something wonky - too long ago, can't remember what it was. Also that
was before I could slightly reflex or droop the flaps while in flight, so the
elevator trim tab is probably unnecessary now. Or maybe not - I'm not changing
anything.
Anyway, on the MKIII, the elevator trim tab is optimized for solo flight, it has
a spring loaded trim lever that is used when carrying a passenger because there
are radical trim changes when you add a passenger. The MKIII spring system
works good, no problem.
Then there is the Firefly; we built it with this little spring loaded device on
the front of the stick because pitch trim changes depending on how much fuel
you have left. This is more than sufficient, you only have to move it a notch
or two from full fuel to minimum fuel.

[quote="gdhelton(at)gmail.com"]Hi Richard. Did you get the little beast back in

[quote]
Nope. The primary source of our problems was using a free air engine when we should
have been using fan cooled. Purchased an old fan cooled Rotax 277, now working
on swapping around the best of several cranks, pistons, sleeves, etc. Then
got to figure out new motor mounts.
Only flown the MKIII once this summer, too many projects.
