Ok, so the new Spektrum Receiver comes with a 7.4V 2000mAh battery and charger. I am set here.

The plane has a glow driver and receiver battery both 6.0V 2000mAh. I have an old Futaba receiver/transmitter wall plug charger I could use bot searching for a more practical way.

Two Questions:

1. Is a 2000mAh receiver battery big enough for a (7) servo plane? Throttle, two aileron, two elevator, rudder and retracts.
2. What charger is recommended that I can charge and condition the plane batteries?
