Motor options for the 501X?

[BORMAC]

I have been running my 501X with a 5.5 GTB brushless setup and the car has been getting along nicely but the motor gets far too hot even with the standard spur and a 16 tooth pinion.Just wondering what others are running with success.Cheers-Jason.

I can't tell you what my motor temperature is after a 5-minute qualifier or main, but my 501X is powered by a Orion Revolution (11x2) with 87/15 gearing and no serious heat issues.

Make sure you have the vent holes cut/trimmed out of your body and maybe try lowering your pinion gear by one tooth.

i have also loosened the belts a notch or 2 to help this out as the drive train is quite tight at kit setting.

I ran mine on kit gearing...

Novak 4.5 sintered.. speedo was warmish and the motor was easily touchable after a 5 min run outside in the sun.

Iv cut both the flaps out to aid cooling as well.

Is your 5.5 sintered as it does make a real difference.

Also if you can live with it, turn the drag brake down to 20 % setting. I also find that the car is a lot smoother as it still retains its speed through corners rather than braking as soon as you let the power off.

Hope this helps.

I run the tamiya 9T transpeed. 87/17 (6 minutes races)

I had a 9x1 (brushed) in my 501x today and the top end was shit!

Admitedly I am running the stock spur (96t), but you reckon looseing the drive train a notch or two may be the answer? I'll definitely try this.

Got a 78t and 81t B4 spurs on the way....so hoping this will make a vast difference.

Any other advice on why my 501x was slow (bearing in mind it's stock and just built)?

Cheers.
