Hey Kobago,

Did you put the battery in the tail because the engine was heavier than the YS-160DZ, and what was the complete weight of the engine including the ignition system, and exhaust system? Also, did you have a seperate battery for the ignition system, or did you plug the ignition system into the receiver?

How does the vibration compare to the YS 160DZ? I'm thinking that your solution has the potential to save considerable money on fuel cost over the life of the airplane. Have you done any calculations to compare the cost per flight of the ZDZ40F3A as compared to the YS 160DZ?
