Guys I just dont know what to do. I whant the plane to have plenty off power and everything, but a .91 just sounds kinda big. I have a .46AX and love it, I dont see anything wrong with the AX series except that there a lil mor exspensive. Now on the other hand, having a .91 on it is going to give some serious unlimited vertical. I definately like lots off power, just not so much were I have to start adding tons of tail weight either. Just gonna have to think some more I guess.
