Default Can you name the motor?

I got an old Traxxas 4-tec in a trade and the motor in it is an unmarked all black motor. The only thing I can find on it is "ROAR 98" and "JAPAN" near the shaft, and then "EPIC" and "JAPAN" by the brushes. THe kid that I got it from said it had a stinger motor in it, but I've come to find that I can't trust his word so I question the unmarked motor. Also any specifics or opinions about this Orion motor? Any help would be greatly appreciated.

How about a picture of the motor can too. Seems like a Trinity to me. Only one I'm aware of in that time period with a black can was the Trinity Midnight 2 motor.

I couldn't get the other photos to upload the other night for some reason. I'll try again. Someone mentioned it reminded them of the epic mvp...

plain guess... Non-rebuildable 27 turn 'ROAR 98 Stock Epic/Trinity type motor - should have 24 degrees of timing w/ laydown brushes by the looks of it -

I thought the midnight II's were anodized like a black chrome - I don't recall the painted black type finish, but it's been a while.

Looks like a non-rebuildable Paradox. Was a great motor back in the day

Thanks for the input. A guy at the track that use to build these from epic said it looked like the non-rebuildable mvp's. It's apparently quite worn out and has a lot of black on the comm and windings. Could anyone tell me how to count the turns? I know that the turn rating has to do with the windings of the copper, but is it how many overall or how many around each magnet...? I'd appreciate some clarity if you have any.

It's a stock motor of some sort. 27 turns of 22 gauge wire was the formula if I remember correctly.

It's a trinity based 27t stock, Midnight two or Paradox or any number of other branded motors based on the trinity platform. Really doesn't matter which on as they were all about the same with some minor differences in RPM and Torque. You can rebuilt it by prying the tabs open.

So you've rebuilt non-rebuildable motors before? Do I just have to make sure and not mess up the tabs so they hold well when I put it back together?

To open it was best to SMACK the end of the shaft on a hard surface and drive the endbell off w/o prying...in the OLD days, you had to be careful to NOT hurt the chrome or paint (cause it was ILLEGAL to open them) - but a nice jig made from a small wooden wood clamp with a hole drilled for the shaft to pass through let you clamp the motor can and endbell tight while you reclosed the tabs (use something soft to knock them back in so as to not scar the paint/chrome)

Oh wait - NOBODY ever cheated!!

Iirc the midnight II was black chrome. If you're not racing stock brushed class (long gone, like low gas prices) you can do anything you want. I've even rebuilt them with bearings from mod motors in place of the bronze bushings and cut/timed brushes. I still use them in my crawler and trail rigs. Great cheap waterproof basher motors.

Default Thanks everyone. I got my answer

I appreciate all the suggestions and info. I might use it for a basher motor like slim jim suggested. Anyone know a site that gives details about modifying a motor as you rebuild it. I have almost zero experience with brushed motors.

pretty much all the tuning info you could ever want for a brushed motor...
