Now that the spray-on wax lubricant was applied, the chain (for gear reduction to the prop) was installed and tested to check for heat tolerance and suitability. We ran the engine up to 7,000 rpm...

We had an oiling system for the chain gear reduction to the prop for our prototype, but found that there is a well-proven spray-on wax lubrication that removes the necessity of an oiling system. We...

Engines are designed for different purposes, and ours was designed for flat-out full-throttle use. We recently did a short video of the engine revving to our maximum rpm of 7,200. The engine was...

We have been testing the engine the same way we tested in the wind tunnel. We start with everything on, and then test while removing pieces to see what they contribute to the vibration analysis....
