The shaft length IS NOT 31mm, if i remember correctly it measured around 25mm? Also, keep in mind the bolt pattern is 25mm x 30mm M4 screw. Build quality is good and the finish is nice looking. Won't fit in a Goblin 630 comp. Returned product due to miss information.

Please note that the MAIN SHAFT LENGTH is 22mm and NOT 31mm as stated on the website and on the box. This motor will not fit a Logo 600 SE or any helicopter that has a support bearing for the motor. I have wasted almost 40 on this product just to find this out at the end. This is blatant false advertising on HobbyKing's part. Not a happy camper.
