Thanks for the replies...I ordered some packs using the better quality 1050 mAh's and I'm looking forward to trying them out. I do like the experimenting and research process and have already learned lots from this forum. Well into strengthening the wings now...my current method is to epoxy a balsa reenforcement (1/16 inch weighs almost nothing and REALLY adds some strength once the epoxy sets) approx 12 in long to the top of the wing...works like a charm even on wings that have folded or been weakened by creases in the foam.
