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 23T aluminium horn for TRX-4 steering assemblies
RC-scale 23T aluminium servo horn intended for TRX4 steering use, listed as part TRX4023TA/3H. The component replaces the standard horn to provide a rigid servo-to-linkage interface while an internal spring reduces transmitted shock loads to the servo gearset.
CNC-friendly 6061 T6 aluminium construction with a straight-arm geometry provides a balance of low mass and improved bending resistance at the output. The integrated spring absorbs impact energy and the multiple mounting holes support precise tie rod geometry and throw tuning for competition or trail setups.
Note on fitment: the internal spring increases overall thickness versus slim alloy horns. When installed in the stock TRX-4 servo location reverse the support tie rod angle to maintain clearance; this modification does not alter the front reverse steering gear position.
Packing includes
- Servo Horn – 1pcs
- Stainless Steel Round Head Screw 3×12 – 2pcs
- Aluminium Collar – 1pcs
- 3mm Metal Washer – 1pcs
Compatible Models
- TRAXXAS TRX-4 DEFENDER
- FORD BRONCO 82046-4
- TACTICAL UNIT-82066-4
What material and finish are used?
Machined aluminium 6061 T6 is used for a strong, lightweight arm with consistent dimensional stability under load and common surface finishes to resist corrosion.
How does the internal spring protect the servo?
The spring cushions peak impacts, reducing instantaneous torque spikes at the servo spline and lowering the risk of stripped gears during hard impacts.
Any fitment adjustments required?
Due to the increased profile from the spring, reverse the support tie rod angle when using the original servo location on TRX-4 platforms to ensure clearance without changing the steering gearbox position. Write Product Review Please sign in your account before you can write any review.
