Jet pushers always a tail heavy problem.
 

I took some time to beat the weight in the tail problem. NO extra weight needed completely balances at the COG everytime. :eek: Heard that one before.

Also put the leads of the motor facing foward for neater package. The 1/8" motor shaft is about 3/4 oz. SS shafting. It reaches the cockpit before cutting. With the battery in the foward battery compartments.. then the ESC..then the motor.. a piece of thick walled 1/8" Aluminum tubing drilled to fit the 3 mm motor shaft & the 1/8" driveshaft. 2.. 1/8" sealed car bearings are spaced to prevent the shaft from whipping around.
