The T-Motor AM670 has AMAZING power for your 67" 3D aerobatic airplane, it's the KING of aerobatic power in that size class.
Use with the T-Motor AM116 ESC (it's pre-programmed for the 670 - just calibrate the throttle). For best performance use the T-Motor Carbon 18x8 prop and 6S 4000-5000mah lipo.
Get ALL the power, get the T-Motor AM670!
