Hello Scotty;

Any airplane will aileron roll, however there may well be something required more than ailerons to get it to do so, or at least to maintain the attitude that you want while performing the roll.

I have no clue what you airplane looks like or the size or power. But I assume that it is the standard aileron equipped trainer. Here is the easy way to get something started.

1. Set up your ailerons with at least 18 mm (3/4 of an inch for a standard. 40-46 size model) on high rate.

EDITED to ADD: Seal the aileron hinge lines with tape, or whatever, just as long as they move freely. That hinge line, no matter how closely hinged, is a "mucho detriment" to the roll rate of any RC model. Once had a friend complaining about his slow servos. I told him to seal the aileron line. He did. After next flight he reduced the aileron throws. HA!

2. Set up some differential. The aileron should move more UP than Down. Either by the radio electronically or placement of the servo horns for 2 servos. One servo, use a wheel on the servo, maybe drill some additional holes on the wheel or whatever it takes to have the UP direction move father than the DOWN direction. More UP than down.

3. Another good thing is to washout the wing. If it's standard ARF covering or money-cote style, use your hot air gun and twist the outer wing ends at the trailing edge UP. Play with it until there is some noticeable up at the trailing edge from the center of the wing. Less than desired but I do it all the time is to cut the ailerons back 3-4 inches at the tip, rehinge the aileron and glue the short tip peices back to the wing with a 15-20 degree deflection UP. Makes landings much easier through a more stable approach, especially during the roundout phase.

4. When you want to roll, gain some speed slightly nose down, relax the forward pressure and slightly nose up, relax all elevator, apply aileron and slight rudder, then as the model approaches upside down, bump in some down, (down on the sticks, not the model) and relax it quickly, while continuing the roll then bringing nose to level flight attitude as you complete. Rudder can help especially to start the roll. After a few tries, you will get the hang of when and how much of everything to use for your airplane. Remember the airplane knows NOT where the ground is. It just follows your commands. Use the controls to command your desires.

5. One of the main problems most people have is to use too fast control movement like computer games. Airplanes need smooth control pressures more so than jerking the sticks. No, I don't do 3D. [:'(] I like to fly my models like I flew the real thing. Smooth, quick when needed, but always positive.
