JOK3R setup and tips
The old JOK3R setup page belongs with this class, because a lot of speed comes from careful building, setup and preparation.
Basic setup
- Use the RCIB setup sheet as a starting point.
- Check at least 3 mm ride height before entering the track.
- Start with about 0.8 to 1.0 mm rear droop.
- After every run, check that no screws, body parts or body posts scrape the carpet.
Body mounting
- Use the Phat Bodies M.A.D. Mini body.
- Cut the body only along the manufacturer’s intended lines.
- Place body holes accurately so the body can move freely and does not drag.
- Do not make extra holes or cut away parts for extra performance.
- Use only the included spoiler; the BattCave bumper and diffuser fit the RCIB setup well.
ESC and electronics
- Surpass Rocket 100A remains allowed.
- The Hobbywing 10BL60 G2 is allowed; choose the G2 because it is sensored.
- Use the correct program card to set up the ESC.
- Make sure there is enough room for the sensor cable and keep wiring clear of moving parts.
- The front servo mount creates more room for electronics in the car.
Tyres and preparation
- Contact 50Sh front tyres and Contact 35Sh rear tyres are the base.
- The original tips mention truing tyres towards 45 mm as a practical starting point.
- Spider Blue is used as the tyre additive in the old JOK3R setup notes.
- Let tyres go onto the track dry and follow the approved additive list.
Help at the track
- If in doubt, bring your car to the crew before driving.
- The Mini Masters WhatsApp group is useful for setup questions and parts advice.
- The BattCave Mini support group contains additional build and setup information.
