Nah. She's still not pretty enough. I'm going to rewind a few motor for some friends in hopes to get rid of my RS wire, too. I'm just going order the high temp wire and be done with it. Rewinding is a lot of work to only get one flight out of a motor!

I hear ya- I finally got closer with the last one-
Got 4 flights out of it (still over propped)
So with this last little bit of wire I went with 11 winds, didn't smoke on the bench anyways.
After the sWARm I'll try this one out and see how long it goes.
I bought some bearing oil too.
I think the next weakest link on the FC2812 is the bearings ;)

I haven't had to replace any of the bearings- yet.
Most get damaged because guys like to over torque the mounting screws.
I throw away the little grub screws and use a 3mm machine screw that can be found at the local Home Depot.
I use a bunch of blue locktite too. Sometimes I have to use heat to get the motor out of the mount but I haven't had one loosen since I started using it.

I did buy some bearing oil.
Comes in a little bottle that has a needle on the tip.

I keep thinking about getting sealed bearings, they cost more than the motor does ;)
But at that point I'd have a 30 dollar motor, instead of a six dollar motor.
But just maybe if it's a 30 dollar motor that ROCKS it would be worth it?

Is this thread dead?
Ninja Update:
The Microdan high temp wire makes all the difference on this job.
I have one of these that I have attempted to burn out and it just keeps on going.
I ran every 1300mah battery though it on a hot day- got it so hot the glue on the motor mount started melting.
This would have definitely smoked the stock setup ;)

Trying-
Been a rough summer, health issues and stuff.
Got a bunch of planes that need work and some motors that need rewound.
Time to clean up the hobby room ;)

Yup! teens and 20's , we were bulletproof...hit your 30's and start thinking the warranty might be close to up...hit 40's and then you know for sure the warranty has expired!

Did a bunch of stupid stuff as a kid. Never imagined myself as an old man. Longevity is does not appear to be in the family gene pool, especially for the males. But here I am.

BTW the rewound CF2812's with the Microdan 24 gauge wire are still kicking too...
(see what I did there?)

Thank you, sir. Good to have you back on the forum. I've scratch built a combat wing that will fly circles around the Assassin. At least, that's what I predict. I haven't flown it yet. :D
