RC Drift chassis

Printing Recommendations:

- Designed for FDM printing with 0.4mm nozzle

- PLA-CF delivers best results

- Use textured/matte or carbon-filled filaments (matte PLA, PLA-CF) for pulleys

- Print motor mount in heat-resistant PETG or CNC-manufacture due to motor temperatures

Features (Base Version):
- Fixed caster angle of 3° (for adjustable caster, use the Pro Version)
- Adjustable wheelbase (98–118mm)
- Adjustable width with two arm options (narrow/wide)
- Compatible with 5g servos (e.g., AFRC D1802MG) or programmable servos (e.g., AGFRC A11CLS and similar)
- Front or rear motor placement
- Adjustable motor mounting angle
- Adjustable battery holder (designed for Gaoneng 350mAh)
- STEP files included for CNC-machined parts (carbon fiber, aluminum, etc.)
- Spool or ball differential options
- Optimized for FDM printing (PLA-based plastics recommended)

Upgrades from V1:
- Stronger differential cups
- Redesigned chassis for easy CNC replacement (carbon/aluminum, etc.) – order via AliExpress using provided STEP files
- Two front-end versions: Base and Pro
- Added ball differential support
- Partially threaded screws for arm axles (replaced nails) – easier assembly and maintenance

Pro Version Front End Features:
- Adjustable upper arm positions for caster angle (0-11° range)
- Servo mounting position adjustment for Ackermann tuning
- Carbon fiber chassis recommended (plastic version has reduced stiffness compared to base model)

Some notes and tips

Suspension pins: M2 partially threaded screws are used as suspension pins. For optimal performance and durability, these are recommended. If unavailable, standard M2 screws of the required length can be substituted.

Shock absorbers: Orlandoo shock absorbers are used, as they offer the best value for money. The only drawback is that the stock springs are too soft and should be replaced with stiffer ones.

Ball ends & link rods: Orlandoo ball ends and plastic link rods are used, as they are the most affordable option. The chassis is designed to use 14 ball ends (as included in the set). However, ball ends and link rods from other chassis can be used, provided the link rod thread is M1.6. I usually use Drift Art ball ends due to their higher quality, and they are compatible with Orlandoo link rods, though the link rods may occasionally require slight adjustment for smooth movement.

Steering tie rods: M1.4 threaded studs, made from M1.4 screws cut to the required length, are used as steering tie rods. When using Orlandoo link rods, they must be pre-tapped with an M1.4 tap, as they are designed for M1.2 threads and may crack during assembly. If using Drift Art link rods, it is better to pair them with Drift Art turnbuckles for more precise adjustment.
