I use AAA nimh 720's for my glow .40 & 1/2A stuff.
I also have the AA rx pack that came with the radioset.... no, I dont put that anchor in my DNU
The AAA last for a few flights on the .40
A couple of years ago I tried AAA packs on a 40-sized 3D plane in an attempt to keep the weight as low as possible.
All went well for a while then, on the third flight (about 20 minutes total flight-time) I was taxiing back after landing and lost all control. The plane continued taxiing until it hit a big piece of concrete. No damage, just a broken prop but the receiver battery was *flat*.
I also noticed that the AAA cells would sag really badly when I wiggled both sticks at once (free linkages, no binding). They just have too much internal resistance to keep me happy and I wouldn't dare fly 2.4GHz with them.
But, if they're working for you then I'm pleased to hear it.
