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
MAKX029TS Hardened Spur Gear Details
This aftermarket spur gear set is offered as a direct-fit replacement for ARRMA Kraton 8S platforms, model MAKX029TS. The 29T and 30T gears are manufactured from 20CrMnTi steel and cut to a 1.5Mod pitch to match factory items ARA310920 and ARA311051.
Designed role: built for high-output 8S Kraton variants where a hardened steel spur helps resist wear under heavy load. The gears are intended as the main driven gear in RC drivetrains.
Installation guidance: confirm 1.5Mod pinion compatibility, set correct axial alignment and backlash before use, and re-tighten mounting hardware after the first run to maintain proper mesh without gearbox modification.

The MAKX029TS 29T/30T spur set provides a hardened 1.5Mod steel option for Kraton 8S drivetrains where increased durability and correct sizing are needed for reliable performance.
How do I confirm the correct 1.5Mod pinion match?
Measure your existing pinion module or consult its specification; the MAKX029TS spurs require a 1.5Mod pinion for accurate engagement.
What inspections should be done after the first installation run?
After the initial run, re-check backlash, confirm even tooth contact across the spur, and ensure mounting screws remain tight to preserve gear life.
Can these spurs be used with stock gearbox components?
Yes. They are designed as direct replacements and should work with the stock gearbox when the pinion module and alignment are correct.
Which factory parts do these replace?
The MAKX029TS spurs are sized to replace factory part numbers ARA310920 and ARA311051 when installed on compatible Kraton 8S models. Write Product Review Please sign in your account before you can write any review.
