Unit measures 4" x 2". Made it with stuff laying around left over from other projects. Idea has been bouncing around in my head for a while. Now that its done I can quick thinking about it and move on to something else. I used a 10t pinion on the slave motor and a 15t pinion on the motor to be broke in. Gear ratio of 1.5 to 1. I think I figured the ratio right. If not let me know. It seems to work fine with the stock Kyosho MA motor as the slave. Ran it for about 10 minutes w/2650mah AA. Didn't seem to slow down any. Hoping for 30 min run times. Was going to put a switch on it but didn't have one that I liked. This will end up being an ongoing project till I get it the way I want. Items used:
1. Xmods Gen 1 motor holder
2. 1.5mm CF
3. MA-010 Stock Kyosho Motor
4. AA battery holder
5. Kyosho 10t and 15t pinions

So with air break in, is it better to use a slave motor or to just power the test subject and have it run by itself for x amount of time?

the idea is to "sand" the brushes to the comm by using a slave motor before sending and electric current through the motor that can cause pitting from the electric arc.

I see. How long should this method be done for? And what power does it need?

Ill assume that white stuff is basicly Brasso, correct?

Glad you like it EMU, Roger. Had to play with it a bit to get the gear mesh right. Sounded like a blender. Its all better now.

That looks good. Especially like the routing of the red battery wire out the back of the case, and the gunmetal paint on the Xmod motor holder. Attention to detail FTW. :)

Are the motors effectively secured to the board by mounting tape? Are there any gear mesh problems under power or is the RPM low enough to avoid that?

Thanks. The xmods gen 1 motor holder was secured with double sided foam tape but I ended up gluing it the base. The slave I had to shim up. It was pointed slight down causing a mesh problem. Its ok now, but I will mostly likely glue it down as well. The slave motor actually torques away from the larger pinion a little which is ok but I'd rather it didn't move at all. Maybe I should try some servo tape.
