I caved and got an #M05 chassis kit 😅.
I'll probably still print that #M03 to be the dedicated #CRX chassis, then use the M05 and the #MX5 body it came with for M-chassis racing.
for now, I'm waiting on an aftermarket steering rack and front axles but after that it'll be ready to go!
got a #Tamiya Honda CRX body today and I just remembered there's a 3D print-able #M03 chassis that should work great with it: https://www.thingiverse.com/thing:2909394
Re-scaled the model to make printable might be a few mm bigger or smaller then a original m03. Uses 3d printed spur an counter gear and a traxxas 2388X differential with printed drive cups for the diff. Smallest pinion that can be used with the spur is 21t 48p Uses all the same bearing sizes for a m03 and screw sizes A alternative version of the C4 parts an addons to hold the battery better than with the top little clip that may break clean off. Pin door variation will allow the usage of body clips to retain the ends of the C4 door for hopefully easier battery access. Uses stock screws as well. There is some play in the original model in the steering suspension. I took that play using some delrin bushings i had laying around but washers or printed spacers would work to. Gear box has held up so far with a 1900kv motor and 3cell lipo I would recommend getting the dogbones (ma15) in metal as I've twisted an snapped them even with 3d printed tires Rear of chassis has been modified for rwd modification which is as simple as putting the front arms on the back an the back arms on the front. Fallow original manual here for assembly https://www.tamiyausa.com/pdf/manuals/58211ml.pdf 6-12-2018 Added the spacer that will extend the chassis to the 225mm Tamiya m03-m wheel base Added the spacer that will extend the chassis to the 239mm Tamiya m03-L wheel base
