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 7075 Gearbox Cover and Arm Stabilizer
This precision upgrade is engineered for TAMIYA 1/10 TT-02 platforms and locates at the front and rear gearbox cover positions and the upper arm stabilizer points. Machined from 7075 aluminium to tight tolerances, the components are intended to protect differential internals and reduce bearing clearance for improved differential consistency under load.
The two-piece assembly combines a gearbox cover with an upper arm stabilizer to increase local stiffness around the differential and to control upper-arm deflection that can affect steering and suspension response. Components are supplied finished for a balance of durability and minimal weight and are aimed at hobbyists seeking a precision upgrade without modifying drivetrain geometry.
Packing includes
- Gearbox Cover – 1pcs
- Upper Arm Stabilizer – 1pcs
- Grade 12.9 black Cap Head Screws 3×8 – 2pcs
- Grade 12.9 black Round Head Screws 3×10 – 6pcs

Compatible Models
- TAMIYA 1/10 TT-02TT-02T
For precision-minded builders who want to minimise diff lash and add structural support to the upper-arm area, this 7075 aluminium cover and stabilizer provide a direct-fit upgrade focused on durability and repeatable performance.
What tolerances are expected from the machined parts?
Parts are CNC-machined from 7075 aluminium with tight production tolerances to reduce bearing play and ensure consistent fitment. Always verify fitment on a test assembly before final torqueing.
Are these components intended for performance tuning?
Yes, they are designed as aftermarket reinforcement parts to improve rigidity and differential stability as part of setup and tuning efforts rather than changing gear ratios or motor specifications.
What fastener specification is supplied?
The kit includes Grade 12.9 cap head and round head screws in the sizes shown in the packing list to ensure correct clamping force for aluminium-to-chassis joints. Write Product Review Please sign in your account before you can write any review.
