Dear Sir i havent mucked around with them at all, personally i feel i have solved an issue that stock ones have(ask anyone who runs this same motor), (had to run between rcbazaar to rcdhamaka and back for that), the entire motor bell will get smashed into the ball bearing and following parts if u just tighten a nut on the shaft and use it stock, its a similar problem like of the dt750/700s.
incomplete motor specs were given like mounting holes so i had no idea but these mounts are great for custom made frames of any material.
i have touched only one motor not all and ovalised 'two holes' only of the mount. i dont think 96% is what im trying to recover
. i have spent 350+2800=3150. plus i have included shipping . thank u for the all the best.
if it doesnt sell its becoming a wooden quad because the motors perfectly sound.
