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 40Cr 63T M1.0 spur for EMO gearboxes
Engineered as a robust replacement, this 63-tooth spur is made from hardened 40Cr steel to provide improved wear resistance for EMO 1/5 and 1/6 platforms. The hardened finish and material selection prioritise load endurance and consistent tooth engagement in scale drivetrain applications.
Installation requires confirming an M1.0 pinion, establishing correct mesh and ensuring bearing and shaft alignment. Accurate mesh and straight shafts minimise stress on teeth and bearings. Observe standard precautions with hardened steel parts to prevent chipping during handling and assembly.
Packing includes
- Main Gear 63T M1.0 – 1pcs
Compatible Models
- CROSSRC 1/6 EMO XXL 6X6
- CROSSRC 1/6 EMO XX 4X4
- CROSSRC 1/5 EMO XX2 4X4
- CROSSRC 1/5 EMO XXL2 6X6
A precision-oriented 63T M1.0 main gear option for EMO series gearboxes, intended to raise durability and maintain consistent engagement under heavy scale loads.
What specifications define this gear?
63 teeth, metric 1.0 pitch, hardened 40Cr steel construction, supplied as a single main gear for compatible EMO models.
How should I set up mesh for best life?
Use small shims or adjustable mounts to achieve a slight backlash with smooth rotation; recheck after break-in and under load to confirm stability.
Are there any known fitment caveats?
Ensure the gearbox accepts a metric 1.0 spur and that the pinion matches M1.0; confirm bearing seating and shaft runout before operation.
What maintenance will extend service life?
Regular inspection of tooth faces, keeping the gearbox clean of grit and replacing parts at first sign of chipping will maximise service life. Write Product Review Please sign in your account before you can write any review.
