The motor is great and a good upgrade but it is a must to get the Motor Seat and also another Motor Gear that fits with this motor. The motor has the diameter of the rotor ax at 3mm while the stock motor 390 has the rotor ax diameter at 2mm. If you get the neccesary extra parts the upgrade is great for the A979 model car
