Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Precision CNC-style hardened wheel joints
This pair of wheel joints is engineered for TRAXXAS X-MAXX 8S platforms where improved mechanical strength is required. The components connect the axle case to the front or rear CVD, designed to reduce axial and radial slack and manage higher torque from advanced brushless systems.
Manufacturing details: the joint body wall measures 1.5mm and the shaft pin diameter is increased by 0.5mm compared to the OEM item, while the outer diameter is enlarged from 17mm to 18mm to optimise torque transfer. These dimensional updates focus on precision fit, fatigue resistance and consistent interface geometry with the original axle assembly.
Installation considerations: replacement requires axle housing and CVD disassembly. Use standard RC workshop tools, ensure correct engagement and apply thread locking where appropriate. The product is supplied as a 2pcs set, suitable for one axle location.
Packing includes
- WHEEL JOINTS – 2pcs
Compatible Models
- TRAXXAS 1/5 4WD X-MAXX 8S MONSTER TRUCK-77086-4
- TRAXXAS 1/6 4WD XRT 8S-78086-4
Specified for users seeking a direct, higher-load replacement for X-MAXX CVD joints while maintaining factory axle geometry and consistent fitment.
