If you do would try and get some time on a flight simulator 1st, mainly the response to the stick is Soooooooo much more severe and if you have FMS and download the EFlight Mini Edge and Funtana and the Extreme Flight Extra 300 from http://www.rc-sim.de/ at least you'll get an idea of exactly how different they feel which is the man thing you'll find hard to adjust to and if you've gone to much one way you'll panic and over correct the other which is like the very 1st time you try to fly !!!!!!!!!!!!!!!
Don't forget put the plane on thelowest setting / thows you can as well and if yo're transmitter has the function put in quite a high exponential as well !!!
Good luck !!!!!!
