Racer tether kill strap

After a couple of hard get offs and a a couple of screaming engines the HPI race team is now buying the insurance of a tether kill switch for all of our trials riders. What drove it home was a hard get off one of our riders tood down in Owensville that had the engine screaming so bad it snapped off the crank key holding the flywheel. I’m not a rocket scientist but this seems cheaper than a blown engine.
