How To:
Convert a Universal Starter Box
for Revo 3.3/Platinum

These are instructions for converting a common universal electric starter box for starting the Revo 3.3 or Platinum without an on-board starting system. The starter box used for these instructions is an inexpensive universal starter box that can be found at most hobby shops.

   

 

 

 

Starter box prep

1. Remove lid - Disconnect the starter box lid by removing the two hinge screws and locknuts.

Remove the hinge screws and locknuts. Remove lid from starter box.

 

 

 

2. Remove charge jacks - The charge jacks will need to be removed to make room for the electric starter motors. They can be relocated by drilling new holes approximately 1/2-inch below the original ones. If the charge jacks are not necessary, then they can be removed permanently.

Elevate starter wheel

The starter wheel assembly must be elevated approximately 40mm to reach the Revos flywheel.

3. Disconnect the starter motor wires - The starter motors must be disconnected from the wiring harness to remove the starter motor assembly.

4. Remove the starter motor assembly - Remove the four screws from the bottom of the starter box and lift the starter motor assembly from the box.

Remove the four starter motor screws. Lift the starter motor assembly
from the starter box.

 

 

 

5. Raise starter motor assembly 40mm - Attach a 40mm spacer to the bottom of the starter motor assembly and remount the assembly back into the box. Longer hardware will be needed. Make sure that the hardware you use is the correct size for your particular box. One large spacer or four individual spacers will work. Just make sure that the mounted motor assembly is secure. TIP: A wooden 2x4 cut to fit inside the box will also work.

Install a 40mm spacer under
the motor assembly.
Be sure to leave enough room for the battery wires to pass through.

Trim the lid to clear raised motor assembly

6. Trim the lid - The wheel opening in the starter box lid must now be trimmed to provide clearance to the elevated motor assembly. The opening must be widened to approximately 40mm in width. This may vary with different starter boxes.

  Make sure there is proper clearance
for the starter wheel.

 

 

 

7. Remount the box lid - Use the two hinge screws and lock nuts to secure the lid to the starter box. Do not tighten these screws. The lid needs to pivot smoothly to operate.

Install posts to line up the flywheel with the starter wheel

The Revo must be set onto the starter box in a specific location and orientation so that the flywheel lines up with the starter wheel for easy starting. There are multiple ways to key the truck onto the starter lid.

 

 

OPTION A: Install plastic body posts - Universal plastic body posts can be used to mount onto the lid to key the truck in. Trim the posts to 1/2-inch in length.

 

 

Body post Locations

8. Correct post location - Refer to the picture for correct post locations for the Revo 3.3. The Post positions are marked in red and are measured from the center of the starter wheel to the center of the post location(s). Note: The positions indicated in the picture may need small adjustments for best performance from your personal Revo 3.3 and starter box.


(A) Drill a hole here to mount a post to keep the front skid plate from sliding back.

(B) Use this slot closest to the wheel. The slot may
need to be lengthened a bit to fit the rear skid plate.

 

 

 

OPTION B: Use front and rear E-Maxx chassis sections for drop-on starting - The front and rear center sections of the molded E-Maxx chassis work great for keying in the Revo 3.3. Follow the steps below to convert an E-Maxx chassis into Revo 3.3 starter box adapters.

9. E-Maxx chassis section for front adapter - The front center section of the E-Maxx chassis works great for a front adapter. Cut out the section along the lines shown in the picture with a rotary cutoff tool. Caution: Use proper protective eyewear when operating a rotary tool.

Cut along the red lines. Remove any unnecessary
material from the adapter.
   
Use these two holes for mounting the adapter. Use these locations for mounting the front adapter. The slot on the right will need
to be notched for the outside screw.

 

 

 

10. Mount front adapter - Use the existing screws from the starter box to mount the front adapter onto the lid.

   

(A) The left side hole in the adapter should
line up at the end of the slot.

(B) The right side hole in the adapter should
be positioned in the outside slot,
directly across from the left. The slot
may need to be notched to fit the screw.

Secure the adapter with the screws
supplied with the starter box.

Cut along the red lines. Remove any unnecessary
material from the adapter.
   
Use these two holes for mounting the adapter.

Use this slot for the rear adapter. The end
of the slot at the side of the lid may need
to be lengthened a little for proper fit.

 

 

 

12. Mount rear adapter - Use the existing hardware from the starter box to mount the rear adapter onto the lid.

   
Secure the adapter to the lid with
the existing starter box hardware.

Correct starter wheel rotation for Revo

The engine flywheel rotates counterclockwise (as youre looking at the front of the engine). The starter wheel needs to rotate clockwise in relation to the flywheel. If your wheel rotates the wrong way, just switch electric motor leads to get the proper rotation.


Proper starter wheel rotation

 

 

 

Starting your Revo 3.3 with the converted starter box

 

  • Fill the fuel tank with fuel and turn on the radio system.
  • Set the truck onto the box while keying in the front and rear of the truck between the posts. The flywheel should line up with the starter wheel just above the wheel.

 


The rear skid plate should fit between the two adapter posts
and just in front of the lower rear suspension arms.
