What you will need for this mod:

• Crest Spinbrush
•  RS Stage 2 Motor
•  Pinion Puller
• Small Phillips Screwdriver
• Small Flathead Screwdriver
• Pliers
• Hammer
• Marker

STEP #1

Take your Crest Spinbrush (motors are the same for the classic and the pro packs – so get the cheaper classis Spinbrush) and rip it open.  The outer casing is glued together, so you will have to break the Spinbrush.  We used a basic pair of pliers to help pry it apart.

STEP #2

Next you will need to remove 4 screws to disconnect the motor.  (Keep the screws as they are a little larger than your Xmod screws and are a quick fix when you strip the threads on your car.)

STEP #3

The next task is to get the stronger magnets out of the Spinbrush motor.  Start by separating the motor can and removing the pinion.  (We used a small flathead screwdriver to pry the pinion off and the small metal tabs holding the can together.)

STEP #4

Next remove the armature from the can.

STEP #5

This next step is important if you want your motor to run properly and in the right direction.  Use a colored marker to mark the top of the magnets, you will need to put them in the Stage 2 motor can in exactly the same position.

STEP #6

Once you’ve marked your new magnets, you can remove the small clip holding them in the can and then remove the magnets.  (Use your Flathead Screwdriver.)

STEP #7

Next you need to prepare your Stage 2 motor.  Start by removing the pinion.  Be careful not to break the teeth, you will need this pinion for your final motor.  (We used a pinion puller, this is a tool sold on atomicmods.com to remove small pinions.)

STEP #8

Next step is to separate the can.  This is a little more difficult as the can and bell are connected by some caps.  (Make sure you do not lose the small washer found in the Stage 2 motor.)

STEP #9

Now you can remove the armature and magnets as you did in the Spinbrush motor.  (Make sure to keep the two motors’ parts separate.)

STEP #10

Place your new Spinbrush magnets into the Stage 2 can and then put the armature back in its place.  (Make sure you use the original Stage 2 armature as is has a much better winding then the Spinbrush.  Also remember to put the small washer back in place at the end of the armature.)

STEP #11

Slip your can back together carefully and push the small metal tab s back down to lock it in place.

STEP #12

Replace your Stage 2 pinion or other pinion of choice.  (We used a small hammer to gently tap the motor into the pinion.  You can use a pair of pliers that is opened slightly to allow the armature to push past the edge of the pinion.)
