RES BOA (Battery On Axle) Mount – Capra Axle Center Pumpkin
RES BOA (Battery On Axle) Mount – Capra Axle Compatible
The RES BOA mount is designed for Capra axles with a center pumpkin configuration, including stock housings, Treal, and Super Shafty. It mounts to the stock locations and includes an option to drill through the truss for added strength.
The design positions the battery and servo directly on the axle, improving weight distribution and performance on technical terrain. The rear section includes space to mount an ESC and/or receiver, and the battery tray is slotted for use with a velcro strap.
Originally developed for our Sporky and Proto chassis—built for Free Crawl, Hard Line, and Xtreme Climbing—the RES BOA also fits many sporty-style comp rigs that use Capra axles and have clearance for a BOA setup.
