I checked out HIGHPLAINS link, and here's some highlights;

Q: Why is there metal on the sides of the fuselage?

A: Pulsejets get hot - very hot. If you let a Dynajet run static for 15 seconds or more it will begin to glow red, then orange. The thin aluminum is there to protect the wood fuselage from the heat. The best way to keep the engines cool is to get them moving; that's why it's important to start them quickly and get into the air.

Q: How do you land that thing?

A: Dynajets have no throttle, so every flight is made at full power and every landing is made dead-stick. ...

Q: Where do you fly?

A: You can't fly pulsejet-powered models just anywhere. They make so much noise that you could lose a club field in one flight. We like to take our models out to dry lakes in Nevada where you can't bother anybody, hit anything, or start any fires. You also have a limitless runway, which is nice for emergency landings.

Just the sort of thing that we all need in our neighbourhood to promote the hobby and become friends with the locals... [:'(]
