ArtTech HobbyKing Spitfire
I'm flying this plain also.
She really flies very well and I modified so that I can use also 2200maH 3 cell lipo.
I put markers on wing for CG and this works great for me.
I removed Lipo holder and placed it bit forward and cut out a bit of frame and foam, glued it back in and now I can fly with standard 1300 or bigger 2200 lipo's.
Rest is stock and I removed pilot and landing gear and she is a beauty in the Sky.
