I don't know what seems to be going on but the plane now balances at 115mm (4 1/2") with the engine, tank, ignition, throttle servo and ignition battery in the nose and nothing in the tail. Which is in the range in the instructions. So all I have to is account for whatever weight I put in the tail. The location for the elevator servo's are about 33" behind the wing tube and the end of the motor box is about 11 inches in front. So whatever I put in the tail I will have to put 3 times in the nose.
Two servos with extensions are about 4 ounces plus pushrods if I can rig a push/pull for the rudder. I went to the local hobby shop and all he had was a 2-56 push-pull kit. Does anybody think that will be strong enough? I was thinking about other ways to rig it just using the cable. Any ideas on that?
That is starting to sound reasonable. Probably between 12 and 18 ounces maybe less depending on where I balance it. I don't know what I have been doing wrong but if I keep waiting to get started on it I will end up needing weight in the tail.
