What is a Slipperential?

[RC-Monster Mike]

We tried several versions, including at least 3 designs with a plastic spur - they couldn't take the heat long term. They held up fine for a 5 or 6 minute run, but with a lot of slip dialed in, the heat softened the plastic and it became fairly easy to strip. A plastic spur would likely work for most, but we tested in extreme slip conditions to ensure durability and reliability. We wanted it to be as user friendly and problem free as possible when released.
