Everytime I start the engines of ny learjet for cargopilot, the plane tips backwards. I have made sure the fuel is balanced, etc, but to no avail. If I start to taxi, the plane rights itself at about 20knts, then if I brake it goes back. The differential brakes are way to reactive and it is impossible to turn.
All help is greatly appreciated.
Cargo Pilot only puts the cargo into one station, you have to readjust the loading of the cargo.
