Trouble with Neu 1521

They don't seem to have the 'new' ones yet however...

Here's some Neu news: http://www.neumotors.com/20061222/News.html

I spoke to someone at Neu. She recommended that I use loctite on it and see if that solves the problem. I am going to give it a try, though I honestly would prefer for this not to be an issue for a motor of this price.... She said if it continues to be a problem I can send it in to be fixed.

I'll keep you posted, thanks everyone for the input

@zeropointbug
Flydma cleared their stock (as Neu will sell them directly) and at this price i couldn't resist taking a Neu 1515 (last one on their site) which has now replaced my Neu 1512 in my truggy.

@BashOn
I felt like you did when i first saw my endbell sticking out too far from the can. I instantly had pictures in mind of popped of Feigao endbells. Just glue it before it will pop off and you will have to deal with a grinded rotor. At least Neu Motors seem to have solved this issue with their new version.

I used a thick CA in one of my Feigaos and it worked good. I thought it would be too strong, but I just added a small amout in 4 places. In case you need to replace bearings, all you do is heat it to soften up the CA.

I couldn't resist getting a 1107/1.5D from flydma.com. I got it to compare with a Mega ACn16/15/1. Now I need to find an adapter to fit the normal 540 mounting holes.

Well whoever said the Neu 1521 (old design) has a screw on front bell was correct. I was about to apply some loctite and started twisting. To my pleasant surprise threads started showing. I backed the can out a little, applied some thread lock and tightened it up good. I used blue thread lock. If that doesn't work I'll move to red.

I feel much better knowing that the can screws down.

I would not use red lock tight on that, for 'whatever' reason you might have to take it apart in the future, red will be 'near' impossible to get off.

Yea... and we all know how easy it is to heat up a feigao. Just run it for 5 minutes.

That was a good one. I meant I used my little torch on the places I used the glue. Heat generated by the motor didn't make it come loose.
