Yes, it's a pulse jet. It is a O.S jet which is about 1/2-2/3 the size of the Dyna Jet. It makes the same noise, but is slightly quieter and the pitch is a little different also. Even when I turn up the volume the noise doesn't sound like it does in person.
The airplane is an all aluminum Mig 15 from the 1940's. Dan rebuilt the very poor kit including new wings from scratch, tail feathers and controls. He thanks everyone who has helped him with the project including Bob Wilki and Jet Bill. Without them the project would have never gotten off the ground!
The airplane is a flying treasure like many of Dans' all aluminum aircraft. It is a sight to see........... Thanks for sharing the video!!
