New Site Format
     As you know
  StampedeProject has
  become way more than
  just Stampede, Traxxas,
  to now include other
  RC brands, accessories,
  and cars. I still don't sell
  anything, I just
  enthusiastically promote
  those RC products I think
  are great.
     Take a look through
  the above links.
  I simply had too much
  information for my
  old site format.
  More fun projects
  coming...

How to Gear your RC Rig
Properly Gearing your Traxxas Stampede, Rustler or Bandit

Stock Spur (the big gear) is:
Stampede 87
Rustler     84
Bandit      78

Stock Pinion (the little gear) with the stock Stinger 20 Turn motor is:
Stampede 18
Rustler     18
Bandit      18

Gearing "5 second" Rule for after market motors

The "5 second rule", if you CAN hold you finger on the motor and ESC for over 5 seconds without getting scorched after a little bashing then you have geared properly otherwise drop a tooth or so on the pinion. This applies to any motor type.

550 Motors
It would seem that gearing rule for the larger sized 550 motors would be 7 teeth more than the turns which was confirmed with my Ultra-Rusty running absolutely fabulously with a 550 Monster Max Wild 17T geared 24/84 and the new Titan 12T being geared with a 19 tooth stock pinion in the new Pede (if I remember correctly).

540 Motors - Normal Size
The normal 540 motors should stick to a pinion gear (the small one) with the 2 teeth less than the number of turns on the motor.  As an example, I ran a 15T Trinity Titanite for quite a while and normally geared it a 13/87 with road driving geared at 15/87 for speed but heat must be monitored. 

Brushless Motors
Start with a 12 Tooth pinion and a 87 tooth Spur and see how that goes.  Chances are that with the crazy torque and speed of a brushless motor you probably won't want to go beyond a 17 tooth pinion with a 87 tooth spur.
