Why do we have long nose moments? We have all been duped by the current trend to composite fuses making things lighter. Lightness is great for our sport but the underlying little secret is lack of lightness distribution. Fuses do not have to be so heavy in their tails. But for simplicity, composite makers use one size fits all in their lay-ups. Couple that with composite rudders, hor stabs and elevators, and you are talking 12 ounces at least concentrated at about 36"-40" in back of the cg. Here's where the E guys have a huge advantage with the battery brick, but don't use it to as good an effect as they could because the tails are so darned fat
Jim, I've done exactly what I say in my gasoline powered Delta which uses a Xigris fuse. BTW, 1" sounds really small but it represents about 2 1/2 % of the tail moment. Other than improved groove with the longer tail, I didn't see adverse effects. Maybe I didn't fly it long enough.....
