1/2 of the conversion done. Only 1 trip to the hardware so far. The manufacturer recommends d-shafting.....so hand files it is...

I also decided to get some bolts and cut the heads off, pour on the loctite, and get some washers/lock nuts fir the outside. Left myself as much thread as the original plus some extra. A little surprised to find m4 metric hardware.

finally 1 side installed on the car. 10mm nylon spacer to make sure the alignment with the spur gear stays true. Now we can all watch loctite dry together....

It does look like in order to make this work on the spur gear side I need 2 more parts. The aluminum gear hub, and a new spur gear that fits the bolt pattern on the new gear hub. Already ordered....I do wish they had a note on the first part that said these would be required and save me paying shipping twice....
 
Did a little supporting my local hobby shop today. Rear 12mm hex Proline showtime drag wheels. No rubber just yet, but 1 step closer.

I used to have a hobby store [no tracks] about 20 minutes away. After they closed I found 1 about 45 minutes away [also no tracjs], and they have recently closed. The 1 I go to now is about 40 minutes, with tracks, and is the best of the bunch. Hopefully they keep going for years to come.
 
No room for a traditional heatsink and fan combo. But the name of the game is still keeping electronics cool. So....I guess I am gonna try raspberry pi micro processor heatsinks, and thremocunductive 2 sided tape like it was a cpu. Copper is a superior heat conductor to the aluminum hobby stuff anyway.

And we're back....so I think my wheel conversion has looks and performance merit at this point. I need a larger contact patch fir this to be effective. I tried a slow launch up to about 15 before I hit it full throttle....limited to 50%. The best I can do atm is 26mph as the back end breaks loose and the car spins in a circle. The last time did so in a way that knocked off 1 of my oring tires up front and made me glad I had a servo saver.

In other news I now also know the front of body has to come up unless the surface is smooth as glass.
 
What gears are you running? I'm really close with the rail at this point. Battery mounting is about it. I've got 21 pinion and 81 spur. Options are 18 pinion or 22 and 24. The steering on the rail is way different. The entire plate pivots and the steering blocks are locked in. Not sure why they do it that way, but I'm gonna try it as is. Can always be modified later. Not sure how much steering is actually needed.
