brushless revo how to ?'s

[BrianG]

FWIW, I had no problems using the motor brake on my Revo with the CD installed. I just had issues diffing out with it in, and if I put in thicker fluid, I started losing the steering advantage of the CD while not fixing the diffing out issue much. IMO, remove the CD, but that's up to you.

As far as the transmission options:

• Option 1: Two-speed transmission with stock brake and stock reverse:
  You'll need servos for the reverse shifter and the brake. The downside to this is that the reverse stock mechanism is generally pretty weak, especially since you're now using brushless. And you cannot use a center differential because the diff replaces the shift fork, dog gear, and second output gear. You can however still use the Optidrive to help protect against accidental reverse when moving.
  
  
• Option 2: Two speed transmission with mechanical brake and no reverse (the cheap way):
  You'll still need a servo for the brake. Lock the shift fork somehow.
  
  
• Option 3: Two speed transmission with mechanical brake and no reverse (the right way):
  You'll still need a servo for the brake. Install the FOC (forward-only conversion) to eliminate reverse and get rid of the extra weight from the servo, Optidrive, assorted linkages, etc. This option lets you use a center differential if you want.
  
  
• Option 4: Modify the transmission for single speed (2nd gear):
  Lock the centrifugal clutch into second gear. See locking mechanism picture below. You don't have to, but you can also remove first gear altogether for a simpler and lighter tranny. Either way, 1st gear won't be used at all. Locking into second gear is the ONLY option where you can use the brake and/or reverse using the brushless motor.

And here is a method you can use to lock the tranny in second gear should you choose to do so:



To do this:

1. Remove first gear
   
   
2. Do the FOC
   
   
3. Install whatever gear set you want (std, wide, or narrow). Since each of these gear sets just adjusts 2nd gear, you can set a higher or lower ratio right off the bat to possibly allow better spur/pinion selections.
   
   
4. Remove screw, spring, ball bearing, and little grey plastic plug on the centrifugal clutch.
   
   
5. File three half-moon slots in the edge of the clutch lined up with three of the holes in second gear.
   
   
6. Screw 3 4mmX10mm pan head screws into second gear so they lock into the half moon cutouts you made on the clutch.
