Feigao magnet let go

[Shark413]

Serum, it was actually a two-man job. After I put the Loctite #638 on the shaft and inside the magnet (hole) I slipped my alignment tool (basically a big spacer I made from some scrap) over the shaft and clamped the rotor in a vise, snug but not so snug that I could not turn the two magnets. Then using the black line on the two magnets (placed there by the factory) I turned the magnets until the black lines matched up. Then as I held them in place my brother tightened the vise so that everything was pretty much locked into place. I left it that way for 24 hours, then I removed it from the vise, cleaned it up, glued the end piece on with JB Weld and let it cure for another 24 hours. I put everything back together and put the motor back into my truggy. I ran it a bit around the backyard and it felt the same as before (power wise). I still need to give it a good work out at the track to see if it holds up.

That's odd, my 540C 7XL came as a 3 section rotor/magnet. How old is your motor?

I bought the motor from RC-Monster about 2 or 3 months ago. May be the 7XL needs 3 magnets (smaller) because of the higher rpm?

It is odd that your 8xl has only 2 magnets. My 9xl has 3 and other feigao xl rotors I've seen have 3 magnets...
