RE: Is lipo balancer really important?
Texas:
Something very wrong. I'm running the same motor on 10-6 prop, which is the upper limit for the amps that the motor can handle. Runs for 10 to 12 mins. on a TP 1320 batt. Try a little smaller prop and make sure the batt is getting a full charge. Should read about 12.5 volts off the charger. Should be getting about 20 mins on that batt.
