MOC-40021-1

This is a fast RC cross kart, powered by a RC motor and a BuWizz 2.0.



It has full independent suspensions. Double wishbone suspensions at the front with a caster angle, and a rear suspended axle.



The chassis is perfectly balanced: it has a 50/50 weight balance, giving a pretty good adherence at both front and rear axles.



Here you can see the chassis in details:




I made pro instructions using LPUB3D. It may be one of the best instructions you can find, mainly thanks to the help of "buffers". It's a functionnality that allows to modify a part of the model between two steps, as you can see below. However it takes a lot of time! But these instructions are even better than the ones of my Ford Mustang Hoonicorn.










To drive it, you need a BuWizz that you can buy here.

Frequently Asked Questions

General Questions
MOCBoxing is an online store that sells high-quality custom LEGO sets known as MOCs (My Own Creations). We partner with talented designers around the world to offer full kits that include all the necessary bricks and detailed instructions.
MOC stands for 'My Own Creation.' It’s a term used in the LEGO community to describe original builds made by independent designers rather than official LEGO sets.
We collaborate with a wide range of LEGO MOC designers from all over the world—each with their own unique style. You can explore their bios on our site and see the MOCs they've created.
No, MOCs sold on MOCBoxing are not official LEGO products. They are custom-designed builds created by independent LEGO fans using genuine LEGO parts.
Unlike Rebrickable or BrickLink, which require you to find and buy parts separately, MOCBoxing delivers the complete experience in one package, including all parts and instructions.
Products & Inventory

You’ll receive all the genuine LEGO parts needed to build the model, along with a digital instruction manual. Some sets also include custom packaging or thank-you notes.

Yes, you will get a piece of paper with your order that has a QR code link, that sends you to a digital instruction manual created by the MOC designer. We can print instructions at an extra cost, send us an email at MOCBoxing@Gmail.com for further inquiries.

We offer both used or new depending on your budget. When you buy new, we guarantee the highest fresh quality of bricks. When you buy used we try our hardest to get you used bricks above a certain quality threshold.

Currently, we focus on full kits including both bricks and instructions. We may offer instructions-only in the future. If you want us to help you out with finding the best places, or maybe even printing out the instructions , drop us an email and we'll gladly help you out.
