Feigao magnet let go
 

I posted that my Feigao 8XL magnet separated after a few laps around my local track. I have some updates so I am reposting here. I finally got my hands on some Loctite #638 so I applied the Loctite and made a jig to hold the magnet steady while the Loctite set. I used JB Weld on the end cap and between the two magnets. I have it back in my truggy and will try it out this weekend. I hope it holds up because I have 4 Feigao motors and I hear this happens a lot.

Separated magnets, shaft, bushing and magnet end cap.

Rotor clamped to keep the magnets aligned while the Loctite sets.

How did you aligned the rotor? with the magnets being pushed away from eachother?

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...

Yeah, my Wanderer 9XL and 10XL both have three segments. My 9XL is about the same age, maybe a tad older, but I can't remember now. Maybe it's something specific to the Feigao's, or maybe just the finned versions?

My finned 8xl had two segments and I bought it about a month ago. I guess it would be better to get the smooth canned xl motors because 3 segments of equal length seem like they would more consistant than 1 short segment and 1 long segment.

My 9xl was the finned version and it had the 3 magnets, so I don't think that it is only for the moth can motors. It seems like only 8xl motors have 2 magnets...
