Any body had issues getting the CG correct on the Fun 51? I have it set to the manual spec, but was very surprised when I mounted my old, made in Italy, ST 40 on it and had to add 1.5 oz of lead to the tail. I mounted the battery at the back of the wing and the receiver just in front of it to help. Anyway the concern is I would like to put an OS50 on it, but then I'll need even more lead to balance. I have though considered mounting the battery on the side of the fuse aft of the wing to eliminate the need for the lead.

How did everyone else's CG work out? Much lead needed to balance it.

Thanks all.
