Hot Spot CG Location
Hi All,
Can someone give me the correct CG range for a Hot Spot- gear down and dry. Also where is the measurement taken-from the LE along the side of the fuselage? or from the LE along the outside of the fin?
Thanks,
Al Watson

HI all, I made the mistake of taking the CG ,130mm from the start of the wing ,at the fuse, it was nose heavy and I new it was wrong when I flew it.
I flew my Hotspot this past weekend with the CG about 3/4'' back from where I had it. 130mm back from the start of the wing leading edge and what a difference, Great, hardly drops the nose in a bank, landing is so much better, way more elevator authority.
All 3 of my batteries are now behind the CG.

Hi Enrique/Rcpete,
Thanks for the quick responses. As best I can see on the Graupner drawing the 135mm is measured from the wing LE along the outside surface of the fin. Someone e-mailed me a page from Bob Wilcox instructions which said 5.25-5.50 inches back from the wing LE measured at the fuselage. Rcpete I think what you are saying is that the Graupner drawing is the place to be. 135mm is 5.31 inches by my calculation. The difference between measuring on the fuselage vs the outside surface of the fin is approximately 1.00ins.
Thanks,
Al Watson
