Chassis Details

Platform: Off-Road Buggy

Notes: The Kyosho Ultima (2019/2020 Re-release) is a 1/10 scale 2WD electric buggy that revives the legendary 1987 IFMAR World Champion model, enhanced with modern upgrades for durability and brushless power capability.

Understanding fitment results

We compare tray dimensions against verified battery dimensions, applying a 2mm tolerance for cable management and straps.

Spacer Required: The battery is notably shorter than the tray, so a foam block helps prevent movement.

Voltage mismatch: The battery’s max charged voltage exceeds the car’s rated limit.

Hard case required: Some tracks require hard-case packs for safety and compliance.

Low voltage alarm recommended: The chassis may not be LiPo-ready, so extra protection is recommended.

Adapter needed: The connector type differs, so a rated adapter or re-solder is required.

We group compatible connectors, surface “fits with mod” only when an expansion-height path exists, and still recommend verifying wire exit clearance in photos.
