Am keen to resurect this lovely old girl but would like to make sure the CG location is correct before its next flight.Does anyone have this info? A measurement back from the leading edge at the centre section would be very helpful.

I suggest starting conservatively, then moving back if indicated. But that's just me. ;-)

Good luck!

On other forums most owners say the CG should be 4.5 inches from the leading edge measured at where the wing dowel is.

Status: online 		Just a warning that Spitfire will snap very hard if you try to fly it tail heavy. I had one, flew it at 4 in. and it was nose heavy. Lost it coming in to land, got a bet too slow without flaps and it snapped at the end of the runway. The landings are a bit tricky you need the flaps for sure.
