40ma is nothing compared to the current draw of 7 servos in my Ultra Sport 40.
Since I don't yet have a battery pack for my T9CPAS w/TP-FSM synthesizer module and the R-319DPS I've decided to go with a 1650 NiMH pack. That way I shouldn't have to worry as much when running 7 servos in my Ultra Stick 40.
We're also negotiating for acquisition of a Toyota Camry Hybrid which comes with a BIG NiMH pack.
NiMH aren't as hazardous to the environment as are NiCD packs. Dave Thacker of Radical RC says 80% of his sales and 100% of what he personally flies are NiMH packs.
