Yes I do make up my own and have better success than the comercial ones,
What I do with the rejects is pull them down and save the good ones and make up packs and give them to some of the kids that are trying to get into our great hobby
I proved out tonight that it was the packs, I had made up new NMH packs, the Tx had dropped .5 volts after 3 long flights and the Rx was still right up there Mike
