Having been flying a 4*60 since the late 90's, I understand the problem, they are real floaters, particularly with a .90 four stroke with a 13x8 prop. Reflexing the ailerons up about 15 degrees will take out some of the lift on approach, and if you can do this using a landing mode that does it at 25% throttle and less, makes it a *****cat to land. They are great flying planes in all respects, but this will make it a one touch landing with no bounce if flaired correctly.

Works like a charm every time and I cannot understand why folks ignore this very simple little adjustment. Flaps are not repeat not needed. The idea is to reduce lift not increase it. By reflexing the ailerons up a bit, yes just a bit you are reducing lift. This has the effect of allowing you to carry a slightly higher power setting and this allows you to better control your descent profile with small changes in the power setting. This opposed to just setting the idle as low as possible and hopeing.
This very simple old trick cost nothing and almost no time or effort. Its your call.

I will give this a try, simple enough just unscrew the clevis a few turns.
Do you have dual aileron servos, and are you flying a radio with flight modes? If so, then program a flight mode with the ailerons reflexed. This will allow you to fly with them in the normal position, then reflex them for your pattern/approach/landing phase. You might also be able to program the reflex in using a flap setting. If you have one aileron servo, you may want to think about converting to dual aileron servos. The drawback with reflexing the ailerons by adjusting the clevis is you have to fly the whole flight the ailerons in that position.
