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.

Technical highlights
- Material choice: Aluminium 6061 T6 provides a good balance of tensile strength and weight for long service life.
- Fit accuracy: Delrin collars reduce clearance at pivot points for consistent suspension response.
- Setup flexibility: Multiple mounting positions on the lower arm allow precise damper angle adjustments for competitive tuning.
What maintenance is required for aluminium rear arms?
Inspect mounting hardware and Delrin collars after heavy runs, lubricate pivot points as needed, and check fastener torque regularly to maintain alignment and component life.
Any special mounting precautions?
Use the supplied stainless hardware and apply medium strength thread locker on steel screws where appropriate. Ensure collars seat fully to minimise play without overloading threads.
Can I tune damping with the arm positions alone?
Yes, changing lower arm mounting holes adjusts the damper angle which alters compression and rebound characteristics; combine this with shock spring and oil changes for full tuning range. Write Product Review Please sign in your account before you can write any review.
