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 medium carbon steel spur for center differential
This precision-engineered medium carbon steel spur gear is manufactured as an aftermarket replacement for the #6780 center differential used in compatible 1/10 TRAXXAS 4WD models. The component is intended for drivetrain service, repair and upgrade scenarios where a robust steel gear is required to withstand increased loading compared with softer stock items.
Install the gear into the center differential carrier using standard differential assembly practices, ensure bearings are correctly seated, confirm proper gear mesh and backlash settings, and inspect mating surfaces for correct contact. This part is suitable when a direct, material-matched replacement is needed at the #6780 center differential location.

For technicians and hobbyists needing a durable, material-matched replacement for the #6780 center differential on compatible TRAXXAS 1/10 4WD platforms, this medium carbon steel spur provides a robust option; verify mesh and bearing seating during reassembly to ensure optimal life and performance.
Is this gear suitable for high-load applications?
The gear’s medium carbon steel construction increases wear resistance compared with softer stock gears, making it appropriate for higher load or frequent running, provided mating components are in good condition.
What assembly checks should a technician perform?
Ensure bearing faces are clean and seated, confirm axial and radial play is within spec, set backlash and mesh to the vehicle baseline, and inspect the mating pinion for wear to prevent uneven loading.
Does this item require different lubes than stock?
Use standard differential lubricants recommended for steel-on-steel engagement and follow scheduled maintenance; proper lubrication reduces wear and limits noise from increased material hardness.
How should I inspect for wear after fitting?
After initial running, re-check mesh and backlash, inspect contact patterns across gear teeth, and examine bearings and spider gears for signs of abnormal wear or scoring. Write Product Review Please sign in your account before you can write any review.
