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
Spring-treated #45 rear axle shafts for trail use
This 4 pcs axle shaft set replaces the rear shafts on TRX4 Trail Crawler axles and is intended to transmit drive torque into the geartrain and wheels. Material selection is hardened #45 steel with a spring steel tempering stage to improve surface hardness and resistance to abrasive wear while maintaining OEM form and fit.
Dimensional fidelity is maintained with long shafts at 68.5mm and short shafts at 59.5mm; the set includes two of each length to cover both sides of the rear axle. Interface geometry and mounting features follow the original shaft layout so the parts locate in the existing axle housing and mate with the stock assembly.
From a service perspective these shafts are specified to extend life under sliding loads and low-speed torque events typical of crawling. They are intended as a direct replacement to restore proper spline engagement and reduce shaft surface degradation.

What is the hardening process used?
A spring steel tempering stage is applied to hardened #45 steel to raise surface hardness and improve resistance to wear and surface fatigue.
Do these shafts alter spline engagement?
No. The shafts are produced to match original spline dimensions and mounting geometry so engagement with the stock components remains unchanged.
What inspection points should I follow?
Check splines for wear, confirm straightness, and inspect surface for scoring after heavy use. Replace if deformation or excessive wear is detected. Write Product Review Please sign in your account before you can write any review.
