I tried out the CBP 1050's today and got about 10 minutes of flight times. They are getting better and I assume they will continue to last longer with each cycle. I am using the charger that came with the Aerobird. It is a peak charger that has an adjustable charge rate. For the initial charge, I charged them slowly at about 400 ma. I thought that would be better...... maybe not??? Anyway, I charged them at 1200 ma the second time. As I stated earlier, the flight times were a little longer, but that may just because they have been cycled twice. I'll see how they are after 5 to 10 cycles. As far the the motor running faster, it doesn't but I wouldn't expect it to since the voltage is the same as stock, just more capacity. I'll let you know after a few more flights.
