Frenchie, my servos are pretty much locked in place because my tank extends into the area above the wing's LE. I normally don't put too much stock into balancing a plane before it's covered, but you are right, it's good to check just in case the balance is grossly off. I definitely believe in options though... Right now I am able to use a small 700mA AAA pack or a larger 1200mA AA pack. the AAA pack will fit in 4 various accessible places in the fuse (2 fore and 2 aft of the CG) and the AA pack should fit in 3 places. I threw it up on my balancer, and unfortunately, it looks like the plane may be a little tail heavy once it's covered, which wasn't what I was expecting (it balanced 1/2" in front of the recommended CG point, but no prop, no spinner and no covering). I have more options for a nose heavy plane, but I only have the battery pack and adding weight to the nose to combat a tail heavy plane. I'm going to use ToughLon covering which is kind of heavy to boot (I'm boycotting MonoKote), so I think I'll just have to wait and see where it balances and hope for the best.

Thanks for your input and good flying, Jerry
