yeah i definately had to add a few sticks of lead to the back even after moving the reciever and battery back as far as they could go in the fuse. Probably about the same problem the guys running the 82's are having.

The only things ive ran into that i wasnt real happy about with this model were....the back of the fuselage where the servos are mounted is extremely flimsy and was flexing like crazy when i was working around there........A little bit stiffer grade balsa or some cross bracing would work well. the other thing was i had to do alot of cutting out of the servo opening they were a good 1/16" too short. are other brands of servos shorter/ narrower possibly?

are you having any problems with the exhaust hitting your servos in the back? mine seems to line up exactly on the exaust. I cant wait to fly this plane it has a very different profile not only with the very tall fuselage proile but also the long fuselage and seemingly narrow wingspan........
