The rocket is a great looking plane but when in the air there is to many white arears both top and bottom and you quickly loose orientation. I bought it because it looked fast, but it is tail heavy with 3 servos in the tail , I would put them in the fuselarge if poss. I fitted an Irvine 53 2 stroke in mine, on its side with the exhaust neatly cut in the bottom. I did have to shorten it and remove the baffles or it would not exit the cowl, this made it sound a bit more raw, had an 11x7 pulled it great until the elevator hinges pulled out and nose dived into the beach, make sure you use a realy thin CA or those hinges WILL PULL OUT. Good luck
