I have a World Engines Expert FM radio with a snap roll button. I tried using it a couple of times but it never really impressed me and I don't think it would be the solution to a perfect aileron roll. Like someone else pointed out it just flips certain servos to a preset. I think mine fed in full aileron and you could dial in the amount of elevator to help with the nose. But if I recall correctly it never did a very good job with my P-51. It just never looked smooth.
Since we are talking about aileron rolls and smooth, I used to fly at a local airport. We had an ultralight hangered there and had full permission to fly our rc planes. Our only rule was that when a real plane came in you landed and got out of the way. Anyway I was out flying one day and this older gentleman came up. Started asking me about my P-51. So I landed the other plane I was flying and told him I would take it up for a spin. I have a four stroke engine on it so while it doesn't sound just like a P-51 it does have a nice growl to it. I got it up, pulled in the retracts and made a couple of circles. Then I went out wide and came screaming down the runway about 10 feet off the ground and after I passed us pulled it into a nice slow victory roll and then peeled it off the to right for another circle. I look over and the old guy is standing there crying. I didn't say anything but kept flying for a few more minutes and then landed. He told me thanks for flying it and went on his way. I am not sure what his connection with the P-51 was but that slow roll really hit home.
