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
Rear hub upgrade for YK7081 platform
This RC rear hub is made for the YIKONG YK7081 TB8 and is identified as TB8/022. Machined from 7075-T6 aluminium, it replaces the factory 80006 hub and is supplied with larger inner and outer bearings to address wear commonly seen on 1/8 4WD vehicles.
The kit includes an oversized inner bearing 20x30x7mm (original: 20x27x4mm) and an oversized outer bearing 15x24x5mm (original: 15x21x4mm). These larger bearings increase the contact area and can reduce wheel-end play under load.
Hardware and accessories are delivered pre-assembled. A medium-strength screw threadlocker is recommended on fasteners to keep assemblies tight during running. Installation follows usual RC maintenance steps: remove the old hub, fit the new hub, confirm bearing seating, and secure with the supplied fasteners.
As an aftermarket hop-up, the hub aims to increase durability and improve repeatable rear geometry. Expect a firmer and more consistent hub interface compared with softer stock alloy parts, which helps with traction and suspension tuning on various surfaces.
