Go figure that out! (Trim business...) H...

I'm still on my RTF Accentor's case.

It was loosing tension on inside loops. A careful look revealed what I though was the culprit: the hinges on the outboard wing were out af alignment, and the wing had more lift than the inboard one. I had to cut the hinges off (the builder was good at making them hinges bullet proof...) and put new ones, in the right alignment.

Today I went flying, and the plane still had the problem, though a little attenuated. I got angry and just tweaked the flaps.

It's almost there. The funny thing is that now the outboard flap is aligned with the elevators, and the onboard flap is a little low. I mean, stab - level, outboard flap - level, inboard flap- a little low.

What could be wrong? Warped wing?

I'm also considering more wingtip lead and giving the inboard flap an extra inch.

Another thing, the inside loops are really hard to make round, I have to comand all the time, while the outside loops almost fly by themselves.

The good part is that The plane was making beautiful landings. It glided in slow motion, like I only saw Bené doing. Unbelievably slow! You'd have to see it!

The wingovers are getting better and better...

Yes, there could be a warped wing (or tail, or...) Does it fly level upright and inverted? If the outboard tip is high both ways, or, when you get it balanced (high one way, low the other--tweak the flaps) then add tip weight. Otherwise, work on tweaking. Adding more inboard flap is a bad idea. You will end up with wing wagging in the interesections. Most people are now going to larger outboard flaps.

One thing to check is the levelness of the flaps to the elevators. What I mean is, are the flaps deflected when the elevators are level with the stabilizer? When inverted are the flaps up? This will make a plane glide slow and forever as you mentioned, but it messes up the inside and outside turn. You end up not having enough elevator in the inside turns which could be why you are having to make constant corrections. Lock the elevator at neutral and then see how the flaps are doing. If they are not level, tweak them up (or down) to make them level with the elevator. (Or you could lock the flaps and do the same to the elevators). You will sometimes get the horns slightly off kilter doing it this way, but it is better than having the flaps deflect more one way than the other in relation to the elevators.
