Hi All,

I am new to the R/C'ing and I have a trainer 40, however a friend of mine is building an old Thunderbug 40 from Balsa USA. His instructions do not tell him how to mount the servos on the plane and since it is a low wing plane I am guessing he would have to mount the servo's upside down. Am I correct on this? Also on that specific plane what is the distance that the engine should be from the firewall as the instruction or manual doesn't say anything about either one.


Thanks very much in advance,
