I put my new 540 Crawl Master in my Wraith and I can not get it to go in the right Direction, it has 6 deg of timing so it should go faster in forward but its slower. its faster in reverse. You cant flip the motor so....

Here's the things I have done so far.

Reversed the TX, still faster in rev,
Reversed the motor wires, still faster in rev,
Re-programed the ESC after every change.

So whats the problem. Am I missing something?

Put the motor back to zero and see if it changes

I have never timed one of these motors. John timed it at 6, so looking at the back side of the motor I see a 0 on the can and 4 marks on the end cap. He has it 1/2 way between the 2 left marks. do I turn it to the right to the first mark and that would be 0 timing? the motor turns counter clock wise in the wraith.

Check the motor direction your ESC is set to. Make sure it's not in the reverse mode.

I was using a RS PRO, that had it. Now I'm using a FXR and I dont see that anywhere in the pc set

Pretty sure the Wraith uses a reverse-rotation motor.

So, rotate the endbell to -6 degrees timing and reverse the motor wires and all should be well.

jpboy · 07-09-2011, 07:26 PM

You would turn it to the mark closes to the zero which sould be the last one are you talking alot faster 6 degrees is not alot of timing

Ok, Like I said in the above post I don't know which way to turn the end bell I've never done this.

The Doc · 07-09-2011, 07:29 PM

I'm going to turn the end to the right and than go the same past and that should be -6? should I do this or just keep it at 0

Try zero first and go from there

Go the same past.

turn the endbell 180*, the red post (+ side) of the endbell should be at the 0 hash mark on the can at 6* of rev. timing. ~ loose interpertation of JRH's words. aka it needs to be a reverse rotation motor.

also if people specify "wraith" timing when ordering a motor for a wraith it comes reversed.

The Doc · 07-09-2011, 08:16 PM

Thanks for every ones help, I went -6 and reversed the motor wires and seems to run good a tad faster in forward. But if a motor is made to run in one direction and you hook it up backwards will that be bad or make the motor wear out faster. I'm asking because I'm not a electrical guy.

I did tell him it was a wraith. Now I'm getting lost did you see above what I did, should I do the 180 deg instead

meatmonkey · 07-09-2011, 09:23 PM

Other than the timing the motor doesn't care which way it runs. If the timing is at zero the motor will run fine in either direction.

No, you don't need to do the 180 degree switch. It has the same effect as swapping the positve and negative wire.

+1, doing the 180* swap just means no desolder/solder steps.

Why do people buy motors without understanding them.
go to my site and check electronics 101.

Thats funny.. As a business owner I can understand where your coming from BUT, unfortunately everyone does not know everything. You have to start somewhere. (not being a smart ass) You have helped a lot of people on here and you make some nice products but I'll bet you did not know everything about the product before you have bought it. Now... I did come from your site and you have one hell of alot of info there

Nice job.

Thanks for the link, never saw it on your site before.

Your absolutely correct. Which is why there is information in the electronics section of this website in a sticky, my we site has a bunch, and even johns threads have information. If I am correct, he also sends a flyer about your motor with every purchase.

I apologize if I came off wrong or rude. Im in an emergency room waiting area for my brother in law.

The wraiths are pretty hard on motors.....I recommend running them on the tame side until you get stuff figured out on them (gearing, drivetrain binding, etc)...

I know I was, and I believe john was too given bad info on the wraith motor rotation.

I would just rotate it and set it at 0 and see how it runs....the trucks are already pretty damn fast, especially if you are running 3s or 4s...
