New product  from British brand Blackbone RC, this clutch provides 10,000rpm+ engagement rpm! 
 
Ideal for 26-34cc ported motors which need a higher engagement to bring the launch straight into the powerband for hard launch!
 
NOT suited to big bore engines (too high engagement rpm - will cause excess slip on taller gears and not required for bigger torquey engines anyway)
 
The spring is made from 3mm thick High Carbon British Spring steel and coiled as tight as possible on some custom spring tooling to get maximum rpm! Coated with heat resistant paint to prevent fade over time.
