Chassis Details

Platform: Capra

Notes: The Axial Capra 1. 9 4WS RTR is a 1/10 scale rock crawler designed for exceptional maneuverability with out-of-the-box front and rear steering (4WS).

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.

Fitment Notes

Space is tight on this chassis. We recommend shorty packs when possible.

Wire routing is tight on this model. Verify top-exit or flexible leads before buying.
