I have a question regarding the Aileron of the Thunder Tiger Slow Fly Cub. The instruction indicates that on low rates the ailerons should move 5/8” up and 3/8” down. Also, the high rates should move 1” up and 3/8 down. Why do I need to do this? And what are the consequences if I go to even throw up and down.

By the way this little bird is FUN to fly…

The differential is to help overcome a couple of "bad habits" due to the high lift wing. Any plane with a huge flat bottom wing will roll in a more axial fashion and have less adverse yaw with a bit of differential. That is the extra up in the directions. Mine was set up with equal throw, and was fine. I wasn't trying to win a pattern masters. I fley mine like a fun fly.

I had a 46 LA in the nose, and a MA 11x5 prop. It was a blast, and not a slow fly anymore. It hated outside loops, but everything else was fun. I felt like I could fly it in a high school gym.

Good luck.

Hay TailTwister thanks for the info. I will give this a try next tiem I am at the field and see what happens.

I have a Magnum 25 bushing engine on it right now, but if I do go to a .35 or bigger engine will I have to use bolts to mount the wing on or will the rubber bands handle it?

Mine went on with bands. I put four on each side, front to back, then one diagonal each way. I flew it pretty hard like that.
