Just got The World Models Spitfire
Thanks for the info!
Regarding the CG......They say 4.05" or 103mm. I balanced mine exactly at 103mm. As I said in an earlier post, on the first flight I had to dial in all my down elevator trim and still hold forward stick to get straight and level. I flew it 2 more times with some down elevator dialed in at the clevis and the trims at neutral. It landed like a trainer so I'm not sure if I should play with the CG or not.
Airborne Models is the US importer for World. They already responded to an email I sent them about the elevator coupling rod and the retract servo mount. Maybe we should get in touch with them and see where they CG'd their test plane.
