Beautiful job Jairus - I especially like the gym shoes, that's a great detail.

Beautiful build, Jairus!

 

I'm curious about the motor you put together with the FK can and JK endbell. Would you be willing to share how you did that, or is that a trade secret? I've accumulated quite a few of those cans and have thought it would be fun to experiment a little, but I didn't think there was really any good way to to reuse anything like that.

It's actually very simple. 
Cut the can at the crimp mark and dissemble.
The JK endbell fits perfectly since it's an FK sized motor, except the can on the JK is really weak where the FK drawn can type is quite strong.
The end bell and can received ball bearing races.
The magnets are replaced with NEO's and holes drilled for endbell screws.
Arm is a JK outlaw type wind and when assembled with gold dust brushes screams beautifully.

I actually mounted the motor in a JK Flexi chassis and raced it for quite a few races at the local track. 
It does run warm so the heat sink is necessary.

Very cool ride Jairus!

 

Thanks for sharing the pix!

Thanks, that's interesting. I'll have to experiment a little. I never actually compared side by side, but I was assuming that the dimensions were different.

 

What specific arm did you use? Was it a Hawk 6 type arm, or one from a crimped endbell Hawk 7 or similar?

[Jairus]

I don't remember exactly.  Could have been Koford.  All I know is there is a tag on it and the stacks are red.  It was sold as an "outlaw" FK arm for the JK motor back when I built the thing.
