Warning- These insanely small RC builds are for the experienced hobbyist only. This project requires in-depths knowledge on soldering and programming RC car transmitters. I try to include everything you need in order to improvise a micro RC build. This is not an exact guide.
I recommend you DO NOT USE your favorite car if this is your first micro build.
Overview and Notes
- This is a 1/64 3d printable kit car I've been working on for a couple of years now I call the RAPID64.
- It's designed to fit inside the car body of most hot wheels due to its adjustable chassis and low-profile
- You are free to upload individual mods to this, but not allowed to modify the existing files and repost them
- This is the beta release, pls leave messages if you have any ideas
- Magnetic body mounts are in progress
- Cost is around $75 in total, but the $30-40
RC4GS
Remote can host 30 different RC models for other projects
- most thing you buy will come with extras so rationally you can build multiple ones for less once you start accumulating
These files are
optimized to work on a 0.2 nozzle
ONLY with quality PETG. Originally this was fully designed for resin printers HOWEVER SLA prints tend to brittle and fall apart especially with CA glue. High quality PETG is the best because of its flexibility, corrosion and heat resistance, low-friction and printability.

(Wireless earbuds are necessary for the
charge board and MICRO Lithium Ion Battery.
You can also reuse the speaker and module to add a Bluetooth radio to your 1/64 RC car)
1/64 Wheels-

Find/buy your own assortment of wheels (3d printing them is a bad idea, AliExpress has some cool sets with rubber tires)
Yes, you CAN print/buy Drift wheels and use the integrated Gyro for a drift car!!!
PARTS FOR REAR CHASSIS
REAR CHASSIS OPTION 1
Dual Shaft Motor

REAR CHASSIS OPTION 2
Any
9 Gram Servo
-

(Disassemble for spur gear, pinion and motor)
(9 Gram Servo is disassembled for Motor, and Gears- optional there are guides on how to turn a 9-gram servo into an ESC as well)
OPTIONAL- You can make a Micro ESC From the disassembled 9-gram servo.

Steel Metal Rods 1.4mm thickness
for rear wheel axle (this is only if you're using a single shaft motor with bearings)
1.5x4x2mm Flanged Bearings
for rear-

(not necessary with Dual Shaft Motor)
I use actual steel bearings and 1.4mm axles because this is where most micro RC cars tend to warp and become un-drivable due to gears skipping.
For the front axles- I recommend using the 2 of the 4 long screws that keep the 9-gram servo together. They're strong and the phillips head is useful for unscrewing the axle if it's accidentally glued into the knuckle.
Instructions Coming Soon-
This is highly in-depth. please to not attempt to build without previous experience in micro RC car builds.
If you are experienced and understand the DasMikro diagram, then no one is stopping you
