RE: SNap rolls?
I'm new at this too. Here's how it was describe to me. You ge the aiplane close to stalling and then you get one wing only to stall first. I think you do that by kicking the rudder over. Then the aiplane stalls on one wing and flips over to that side. That is all I know about them.
I've done aileron rolls with my trainer. It goes over a bit slowly. It also helps to add a bit of down elevator as you go upside down to keep the plane level. It is pretty easy as long as you don't freak out in the middle and have some room under you.
To bad my trainer is 75 feet up in a tree now and that is where it is going to be for a long time. I'm just putting another one together tonight. I wish I had crashed it insted - at least that way I could salvage the engine etc. Oh well.......
