Well guys, I put everything back into the plane. I prime it up and when I am ready to start it the fuel runs back into the tank. Would I be correct in the assumption that the tank is too low in the plane. The plane is an Explorer 40 ARF and if I am correct then it either requires some surgery on the plane, or I would have to invert the engine and change the throttle linkage.
I did get it running in the plane with a mate holding it slightly nose down, once running it was fine due to the pressure from the exhaust in the tank (I guess).
Anyone else have this trainer and if so any ideas?

Regards,
Jason.
