This JR-THS15-BK steel propeller joint from JAZRIDER is an RC-scale replacement part intended for Tamiya Hotshot style buggies. It serves as the mechanical linkage between rotating props and their mating components on Hotshot, Hotshot II, and Super Hotshot layouts, providing a direct swap for worn or damaged original joints.
Package content is 2 pcs per set, sized to match the original Tamiya connection points. The part is made of steel, so its role in a model is primarily durability and consistent mechanical mating rather than weight savings. Use it where the factory joint shows wear, cracking, or excessive play.
Installation notes: verify fit before final assembly, check alignment of mating faces, and confirm fastener lengths and thread fits from the existing assembly. The part is used in the driveline area of a 1/10 scale Hotshot family chassis, so basic teardown of the rear assembly may be required to access the joint. Minimal trimming of adjacent components should be expected only if prior repairs altered surrounding geometry.
Tuning and maintenance role: replacing a worn propeller joint can restore precise steering geometry and reduce intermittent binding under load. After installation, perform a low-speed functional check and then a short run to confirm there are no unusual noises or play. Periodic inspection and light lubrication of adjacent bearings and pins will help the joint perform as intended.
