I've thought about building some 2P 3 and 4 cell packs for some of my bigger foam planes. (1600-->2000mm) The 2/3 cell packs I bought a while ago are only 1P 10A which is great for endurance on my strix nano goblins, but not so great for power. Should start with a set of 1P 20A 2/3S packs for those. A slightly flatter/wider 3s pack would be nice in the NG. I might even give em a go on the FT Trainer.....I'm planning on getting some 6s built up for that crocodile quad
Cheers!
