Gordon You and I are in the same boat. I fly the Trex 450V2 aswell as you know from my previous post, and if you can handle that bird in figure 8s you wont have any trouble flying the mustang. I only had 2 previous flights on fixed wing and that was with the high wing trainers or should I say Blimps with a fusalage! lol BORRRRING!! Dont worry my freind, the Mustang was a wise decision and the larger motor will only help. Just because you own a Corvette(Mustang) doesnt mean you have to do 180mph all the time. It comes with a trottle stick.

Definantly take the gear doors off though! they really srew up the flight caractoristics.
