I have 3 "new" motors that I'm pretty sure are leftover Paradox handouts. Would like to set them up and break them in and give them to some new racers. Might even run them for a club race. Just curious how to set them up (springs, brushes) and what rollout to use. Did a fair amount of searching and all I found was 1 post (red/green springs) and another 24-26mm rollout (0.95 - 1.05 range). Large track with several tight corners. I have a motorchecker but not a load dyno and usually our track doesn't give us much practice time with the computer set up, so hoping to get close without taking much time on it.

Allright... you can stop laughing now. I know some of you have run these, it's only been 3 or 4 years... so please let me know (questions above).

Default Help with Core Stock

The Cleveland Indoor Champs just announced that the hand out motor for this year is Orions Core Stock. I've never run these types of stock motors, so I could use a little help with setup. Any suggestions on brush setup and gearing vs. the Co27 in 12th scale?

Fuzzy- according to Big Jim he said they should be set up like a Reedy MVP. 767 brush on the positive and 766 on the negative. With spring tensions of 6.5 + and 6 - from a fiddle stick gauge. I just found this info from another forum yesterday from a link somewhere in this thread. I think it was at rccars.com I have my son's car running a 35/100 gear combo for our local track with his rollout being around 29-30 and final ratio at 7.14 in a TC4. He is consistently quicker than the Co 27's, but his motor has not been rebuilt yet with the above info.

What current limit would you recommend for 27T? I find that when I hit something occasionally my power goes down because of the current spike. So if you limit the current this won't happen so much. How far do you go though?

thanks
Mike

High RPM w/loads of torque

Carlos, you have Team Kwik, EA Motorsports, and Trinity driver right next to you. You should ask them, that's what the sponsored drivers are there for. To help the local racers.

hey guys,
I've picked up some f-line brushes and was wondering how long you break them in for ? they seem to take an age to get any comm wear marks on them.

Also, a little off the main topic, but the same question for the checkpoint infinity brushes on a 19T money motor

usually on the f-brush it depends on the batch but andwhere from 5 min to
15 , just run for 5 min then check the brushes if not broken in then check them every min or two, you want all the serrations to be shiny..

as for the checkpoints i break them in for 12 min at 1.0v....

same thing tho, make sure that the serrations are shiny

Default Question on motors

The 4499 is a very RPMish brush, so thats a good place to start.

Later EddieO
I always get confused could you tell me if I had high AMp readings on the motor does that mean higher RPM or higher torque and with the high amp should I need to adjust to a larger pinion or a smaller pinion to accomplish fewer minutes per lap.

thanks

Stock racers I have a quick one here I got the new Orion stock 07 motor and tried it today but the motor was slower than my other stock motors I gear it like the CO27 and the motor got real hot 195 deg so I went down on the gearing and the motor got even hotter, my setup was red's on both sides with 4499 brush, can someone give me the setup on how to get this motor to run right, thank you.
