The Pacer motors have become one of the most popular motors in the market, so T-Motor has updated and upgraded their motor to V2! The P2306 V2 is smoother than the P2207 and features a lower throttle to give your freestyle quadcopter a smooth and stable feel. Excellent motor when flying close to objects!
