Here is the Red head Pulse jet engine that I ordered from Hobbyking, I was one of the first to order but one of the last to receive for some reason :( anyway here I show it and explain a little how it works and I also show the spark plug in action. The future plan is to test it on the bench then fit it to a large scale RC car for a beach speed run, lets see what happens :)
