Default Cobalt 8x1 Round Wire gearing

Hi, im in need of a good starting point for gearing my cobalt 8x1 round wire motor w/ the standard xxx brush. My track is 112ft x 100ft. Im using a jrxs w spool up front. I started off running a 9.73 final drive (128 spur & 24 pinion), acceleration was not as impressive and lacked topend. Next test was a final drive of 9.3 (128 spur & 25 pinion), it lacked acceleration, but gained some topend, power hits just right after middle part of the 112ft main straight, then i changed pinion to 26T to get a final drive of 9.0, again, no acceleration but has top end although power kicks in rather late. timing of motor is 12degrees. if i hit a final drive of 9.5, will i be able to hit the sweetspot of the motor? im compared performane of this motor against reedy Ti Worlds 8x2, the reedy seemed to be more powerfiu overall. any tips or advice will be greatly appreciated thanks guys

HI Joe,

It sound’s like you’re still under geared. Around a 8.6FD is what I’d recommend as a starting point for gearing on a track of that size… To help with bottom end torque you can narrow the face of the XXX P-94 brush to 3.9-3.8mm, and bend the springs an additional 45 degrees for more tension (purple springs)…

12 degrees is a good starting point (very neutral)… Increasing the timing will help the motor produce more overall power… Your should first try what I have mentioned and see if helps, then try bumping up the timing in 3 degree increments up to 18 degrees for more overall power……

The 8's with the XXX style brushes seem to really come alive for me when I bump the timing up to around 16-18 degrees .

Hi Curtis,

The motor just came alive w power when i followed your instructions. i hit the track as soon as you posted your reply. i hvent touched the timing yet but im already very happy with the available power, now i got more options with tuning for more punch. What more if I was using a UL Arm, il be flying Thanks for the help Curtis.

Default About the Ultra Light arm

Hi Curtis,

This is my first post here and I'm glad that DC has such a big group of supporter. I recently tuned DC motors for a racer in Reedy Asia. My driver handed me two Cobolt based motors with 8 turns Ultra Light arms. When I looked at it, I worried about the satuation as a lot of metal was shaved away. And the round brushes also worry me as the punch and torque will be less (width of brush is wider than standard stand up brush).

I have several questions that would like to have your precious comment:

1) Will the arm over-satuated easily?
2) Will harder spring for Cobolt base motor available?
3) What config of brush is the best for touring? Stand up size? Round? Or the oringal size and cut accordingly to the diameter of the comm?
4) Will hole drilling on XXX brush help the performance?

Thanks for your advice before hand and keep on your good work!

Schumacher
