RE: Tip Stall Question
Flying never was the problem..only landing.
Already seen some "Improved" landings with sealed hinge gaps and less aileron throw. (I really never knew exactly where to set the ailerons for say..a low rate setting)
Looking forward to trying some of the other suggestions on this thread.
I doubt that she will ever land as easy as a twist or tribute or stick or any number of other planes I could mention but she is already giving me less cause for alarm than before thanks to to friendly advice from those who know more than me. Thats the beauty of forums.

Most of the ones you mention have straight taper wings. There is a reason they have them. Opposite reason the fullscale (and model thereof) of your airplane's wing is tapered.
Don't throw in the towel yet.
Take the sucker up and do some aileron rolls. Fast enough? Too fast? If you don't need how fast it rolls, then move the pushrod out on the aileron horns or in on the aileron servo arms. If you discover you don't need the deflection you're getting now, then get rid of it. And your landings won't be so risky.
And learn to steer on departure and final with the rudder and the airplane won't be so hard to land.

RE: Tip Stall Question
da rock, yeah, thickness is a % of chord, I probably over simplified my question.
Terry, if the issue is mainly landing, maybe you can reflex both ailerons just for landing? I.E., put in a airbrake mix on a switch and raise both ailerons a few degrees for landing. This will increase your sink rate, but will reduce abrupt stall tendency as it puts negative camber into the wing. You could also add a bit of up elevator offset with the mix to negate the sink.

I understand what your saying except for in your suggestions..
3) To install turbulators close to the wing tip s.
4) To short the ailerons from the tip s as much as possible
Could you elaborate a little on these points?
What are tubulators?
By "short the ailerons" Do you mean to take away some of the aileron material at the tips?
and then..
5) Not to use ailerons during landings.
I only wish I were that good of a pilot..I know I would mess that one up.
I cant even do that on a h9 Alpha trainer (or a nextar, or a tower trainer or a (insert your easy to fly plane here)

Yes, that is what I mean by short ailerons.
Yes, you can do it; just practice much, the rudder is very useful.

thank you for the continued words of wisdom. i have managed to implement a few of the suggestions with some good results. ( documented in my last post )
I WAS convinced that I would have to put a parachute on it to land safely ( CIRRUS ) but it is has already improved.
I can see the light at the end of the tunnel now and am confedent that I will reach it.
