The Xpwr T3910 is a small lightweight powerhouse capable of turning a 15x7 Xoar PJN prop to in excess of 1000 Watts on a high quality 4S Lipo (80 Amp ESC recommended). Designed for several new upcoming Extreme Flight models, the T3910 can be retrofitted to current 48" models with some modification to the motor mount (the radial mount footprint is considerably larger than the Torque 2814/820 so modifications to the front of the motor box are necessary).
When pairing the Xpwr T3910 with an Airboss Elite 80 Amp ESC, timing must be set to high on the Airboss 80.
When pairing the Xpwr T3910 with Castle Creations Talon 90 ESC, the Talon 90 must be updated to Firmware 4.22 with PWM set to "Out-runner mode" and timing set to "High".
