No, it didn't. I didn't notice any noise, but I was using a small prop and a tuned pipe so the frequency would be up there.

I had an elevon come loose or something. It started rolling and ended up meeting the concrete. Concrete-1, Mach Racer-0, engine-0, radio-0. The wire hook that I held it to the launcher with was OK.

I gotta get me another one of those planes and a couple of pylon props. I have an OS .50 and another of the Rossi mini-pipes waiting.
