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
Rear Centre Drive Shaft for TRAXXAS 1/7 Platforms
This aftermarket rear centre driveshaft is designed for TRAXXAS 1/7 Unlimited Desert Racer platforms and serves as a direct alternative to factory part number 8555 on RC-scale vehicles. Built from 4140 medium carbon steel, the shaft aims to offer increased toughness for the centre rear driveline without changing the vehicle layout.
Specification details include a 6 mm dogbone thickness for greater resistance to twisting under load compared to thinner stock dogbones. The part installs in the rear driveshaft area and uses the standard mounting hardware included in the kit to secure it to the driveline assembly.
Install this driveshaft to replace a worn or broken centre shaft or to upgrade to a stronger steel option for improved durability under frequent high-load operation. Maintain stock setup and alignment unless other drivetrain components are replaced.
Packing includes
- Rear Center Driveshaft – 1pcs
- M4x2.5×13 Screw Shaft – 2pcs
Original Name / Part No:
8555
