"Now that more people are using 17.5's in prep for the ECT this winter, I've had a few people asked me how to mount a smaller size spur gear onto the b4(or XXX) and retain the slipper clutch...

Obviously there is a "slipper eliminator" out there. But our cars have the slipper clutch on the car for many reasons; diff life, transmission wear, handling, and weight bias...

Below I have created a list of parts, mostly AE parts and 1 Losi part to make this conversion.




With this you should be able to run a smaller spur.
These parts you will need to acquire:

This part you will already have-

B4 Slipper Plate (Inner)

On the Losi part A-3124. You will need to cut one end of this spacer flush, make sure you keep the side that is "keyed" the same way as the top shaft. Once this is cut you are ready to assemble the slipper clutch.

I have created a transmission blow apart drawing. This drawing shows the basic assembly of the slipper clutch.

Also shown in this drawing are the new parts used in the assembly, these have been highlighted yellow.


Here is the link for the blow apart drawing-

I originally assembled and it is geared at 31/69. It seems to be pretty close for the power band. But I would recommend carrying a 30,31,32 pinion selection..."

Will the Intellect 5000 30C Lipo fit the B4?

If not what others are people using?

Thanks
