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 hub hex for PROMOTO-MX wheel mounting
This CNC-oriented hub hex is produced as a direct replacement for LOSI PROMOTO-MX 1/4 scale motorcycle wheel positions. Constructed from Aluminium 7075-T6, the component provides a rigid axle-to-wheel interface and is sized to accept the larger inner bearings specified by the part number.
For assembly, confirm axle tolerances and bearing orientation before pressing components. The hex is intended to maintain bearing alignment under torsional and lateral loads; ensure mating surfaces are clean and use recommended interference methods for bearing installation. This item is for scale RC motorcycle applications only.
Packing includes
- Front Wheel Hub Hex – 1pcs
- Bearing positioning column – 1pcs
- Bearing 5x14x5 – 2pcs
- Rear Wheel Hub Hex – 1pcs
- Bearing positioning column – 1pcs
- Bearing 5x14x5 – 1pcs
- Bearing 8x16x5 – 1pcs
Original Name / Part No:
LOS262012+LOS262013+LOS262014
Compatible Models
- LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
- LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06002
Use these precision hubs when a durable aluminium replacement is required to accept larger inner bearings and retain accurate wheel alignment on LOSI PROMOTO-MX chassis; verify final fitment on the RTR before service loading.
What are the critical installation checks?
Measure axle diameter, verify hub bore runout, and confirm bearing seat depths. Use a controlled press to avoid introducing radial runout when installing the supplied bearings.
Which bearings does this design accept?
The hub is prepared for the supplied 5x14x5 and 8x16x5 bearing set with positioning columns as shown in the packing block; ensure correct orientation for load direction.
Any recommended service practises?
Inspect bearing faces periodically, keep threads and mating surfaces free of debris, and check retention fasteners after initial running to prevent loosening under vibration. Write Product Review Please sign in your account before you can write any review.
