Durhas,
In reference to longer wings with standard aileron's: this was a very common Mod in Alaska back in late 70's and early 80's. Of course the theory was by extending the wing
And increasing lift outboard was going to get you off quicker. Lots of the Cubs got converted over, were many times, the Cubs that didn't really "cut the mustard" when compared to ones that were " real performers". And many believed after the mod, that there was a noticeable increase in performance.... However as the years went by ALOT of folks began to REMOVE the extension because story's of these longer winged Cubs
"Getting away" from highly experienced Cub pilots became
Common, when these aircraft were exposed to crosswinds that were manageable in a standard wing Cub.
There had been lots of talk about ALOT of loss in aileron control and harmony, I remember a fellow guide asking me one time if I had flown a long wing with standard aileron's, I told him I had and didn't like them at all in crosswinds. He says, you know a Cub has 18 degrees of
Aileron deflection, but when you extend the wings without
Extending the aileron's it feels just like it has 9 degrees!
Bunch of fellas have tryed simply removing the "wind stops" off the middle hanger to get "overtravel" deflection's
Up/down into the 22/24 degree range trying to compensate for the lack of control, but it made no difference, the ONLY cure was to extend the Aileron's
Out to the tip, that will allow you to regain control of the
Wing again. There has been many dozens of Cubs, rolled up into a ball, by some very experienced Cub pilots with short aileron's on long wings. That's a fact. Be very careful with that combination. This is of course just my own
personal experience with them, your mileage my vary, And to all the guys that own Cubs, with this combination, Sorry if I have offended you in advance!
Best of luck

Ps. So direct answer: Extended wings WITH extended aileron's work fine!
