BTW, you can also reduce cogging and heat issues by setting the ESCs punch control to low and motor timing to low.

Anw, I'm currently running 31/104 64pitch gear. So should I increase or decrease my pinion if I would like to increase my FDR? And decrease the motor heat. (I'm still a little bit confuse on this).

Also for those who are running EZRun / XERun, 9T motor, what are your FDR?

My car are used for drifting.
I run the ezrun in my trf415msx drift car and my fdr is 7.51, 7.20, 6.91. this is with a 79 tooth spur and going in order of fdr 23, 24, 25 tooth pinion. it depends on the track as to what fdr i run. my temp for my motor is about the 40 deg C mark had it at 50 deg C but it was a hot day in the 30 deg C

Hi guys.

Thanks for all the advice. Will try to lower down my FDR at the moment and see what will be the effect.

Hi guys.

I've change my pinion from 31 to 38.
I'm currently experiencing heat issues with my current setup;

Spur: 104T (64P)
Pinion: 38T (64P)
Center Pulley: 18T
Rear Pulley: 37T
Front Pulley: 37T

FDR: 5.62

Should I increase or lower down my FDR? I'm using my car for drifting, so I need more torque.

Also, can anyone explain or provide me a link the explanation of brushless timing?

well depends on how hot it is getting if its ove 60 to 80 degs c then it will destroy the motor. but check with you manufacture

If your car is setup correctly, no binding, rolls smooth with the pinion removed, then go with a smaller pinion.

Please use the search on this sub-forum. Search for "timing".

Use the advanced search, and search titles only. You will find many discussions about it.

I'm not sure of the temp. Not sure of the way to measure it.

Care to explain a little bit more?

1) Remove the motor's pinion.
2) Put the car on a hard surface.
3) Give it a kick....it should roll down the hard surface with no noise, smooth, just like a car on a highway when the driver shifts it to neutral, it rolls for a while.


Is there a local track? I think it would be a good idea to take it there and ask the folks there. Also, if there are hobby shops they should be able to check it out for you for a fee. You would be amazed how much you learn by talking to them. Give it a try.

Hi Ozvena.

Thanks for all the help. I've tried the method you mention above. Found out that if I completely tighten out my wheel nuts it will be very hard to turn the wheel / won't roll down far when I push it.

I've make the nuts loose and it seems to be better. Wheel turns more freely. Any idea what should I check if I want to make the wheel moves more freely?

What kind of car is it? Is there a link to a PDF where I can see how it is suppose to be assembled?

I would say that the wheel bearings are missing a small thick washer kind of thingy that goes in between the bearings.

You can see it here for example:
http://www.hotbodiesonline.com/manuals/67700.pdf

Search for a part number 73507❸ on page 21.

Here is the correct link:

When you remove the wheel and A9 part, do you see that BC11 shaft is installed (page 15)?

I do not not know what else can it be...
