Thanks, Mugenkidd

I have changed to larger wheels. I'll try and move the mains forward, but it will not be by much.
The fields is surrounded by trees and bush, so if its not up and climbing in 300 ft there may be trouble.
Shifting the CG is going to be tough due to the placement of the fuel tank and the limited space in the engine/fan compartment.
Any thoughts on increasing the static thrust by reducing the outlet diameter?
