mine seems to charge up just fine with the TX charger. my flight times are still around 5 minutes, so it might not be working as well as i think, but it does charge, never the less.
got some good video in today, some high flying, rolls, close calls, swoops. pretty fun, far more amusing than the AA IMHO
