Rooster Tail Ultra Clutch System - for use with Losi Pinions (not included). This product is NOT for the larger RCMAX engines that use the larger Black Bone Racing gears

As many of you may already know, we at Rooster Tail Engines design, modify, and enhance standard and performance RC components for extreme output and reliability.

Our engines are modified to deliver nearly 3x the output in the full mod range and our performance modified carburettors enhance engine output, run cooler and remove the need for annoying shaft replacements and carburettor throttle shaft bore failures.

Our high performance versions of the standard Zenoah clutch, Elcon and Lauterbacher 4 shoe clutches, took sand dune racing to a new level, with no heating issues and no fading.

We have now taken clutch systems to the next level with our new RT Ultra Clutch System.

Designed to withstand the rigorous outputs of the big bore motors (up to 46cc), this clutch has been tested for 10 months in the searing heat of the Western Australian sand dunes with outstanding results.

Simple and easy to install, with components we are all familiar with.

When fitting this system to your stock or performance engine, you will notice huge and consistent gains in acceleration.

The system is capable of high slip and high bite to unleash your engines torque potential time after time.

The engagement point is set to 8,500rpm.  Shoe sets with different engagement points will be available soon.

System Highlights:

  • Removes all traces of engine bogging on take-off
  • High quality bell with low wear characteristics
  • Fully balanced shoes for smooth and accurate engagement
  • Super duty spring that we have not been able to fault or need to replace after 18 months of extreme testing
  • Due to efficiency, it allows engines to run much cooler and last longer

Kit Includes:

  • RT Ultra Clutch Bell
  • RT Ultra Clutch Shoes/Spring
  • RT Drive Plate & Bolt
  • Bolt Kit

Kit Requires:

  • Losi Pinions and Spacers to Suit


This system will function in an enclosed carrier, although we recommend the use of an open carrier for best results.
