Default Fuel tank placement for CG.

OK the plane I just bought has never been finished and the tank is in the bottom of the fuselage behind the wing tube should the tank be over the wing tube or in front of it for the CG of the plane when full tank.

P40... You should contact the manufacturers of the aircraft to find out where they have the CG designated.

From there, you will have a spot to place the tank. Ideally, you want the tank situated right over the CG, so that during flight, you won't have a shift in CG when the tank empties. This will happen if the tank is placed either in front of or behind the CG and could create a trim change towards the end of the flight.

I'm guessing, NOT behind the wing tube.
