MRC24 - 3d printed 1/24 RC MOA Rockcrawler

MRC24 is a micro RC Rock Crawler in approx. 1/24 scale using small hub motors to directly drive all 1" wheels. It's a fun toy to climb slowly rocks and terrain. All main parts are 3d printed: chassis, front and rear axle. However, you will need additional electronics and hardware to complete the crawler. Basic 3d printing and RC knowledge is recommended before starting this build. Feel free to mod parts and share them by using the hashtag #mrc24.

This is just awesome! I used to compete in RC crawling years ago. We never had 3D printers or the ability to make something like this. I am absolutely going to build this. Thank you for sharing it all! Subscribed!

Very Nice! Can't wait to print and build

It would be good to get some long term durability tests on that in some real world conditions. Nice idea though I worry about the steering scrub.

[@Unboxingexperience7]

at least spare parts are cheap 😂 I hope to get more feedback on the design and materials. I did some outdoor testing. motor hubs will fail if not printed the right orientation. pla is prone to heat deformation and UV. I had a break at the rear axle, so I added supporting arcs from the axle to the motor hubs. motors hold up well, but maybe they need grease after some time. I will share all my experiences, hope the community does too!

To fix wheel scrub, maybe something like a behind the axle mount c-hub pivot closer to the wheel? Like the rear of the motor would swing. Cool rig, though. Great job.

Can this be done using a different radio? Sonething a little more budget?

[@Unboxingexperience7]

sure, you can use any radio. the cheapest option would be to use a 2 channel radio. you just need to connect all motor wires to the esc. however, you cant control the axles individually.

@@Unboxingexperience7 Cheers mate. What i meant to ask was can i use all these functions on a cheaper radio like a flysky gt5 or g7p. What radio feature do i need to accomplish this? Thanks mate🙂

[@Unboxingexperience7]

programmable 3Ch radios should be capable of individual axle control. search the internet for moa (motor on axle) programming on your desired radio.

[@vhrte49]

@@Unboxingexperience7 Cheers 🙂

Nicely done. Nice printer setup too! Why 99% infill not 100%?

[@Unboxingexperience7]

Thanks! I use gyroid infill pattern which is limited to 99%. There are other patterns allowing for 100% infill

nice... sell done

LooKing firward to outdoor test

Can I use a 3ch transmitter with this design?

[@Unboxingexperience7]

3CH will work if you are able to mix the 2 channels for the 2 ESCs on the trigger of your radio. If not, just use 1 ESC for all 4 motors and 2 channels of your radio.

[@ZorAxe]

@@Unboxingexperience7 Ok great. Yes I think I can mix channels. Thank you for sharing this. Very impressive
