This is a Bob Maddox 50lbs pulse jet with V1 type valves.You can bye them off him or even bigger off RU-vid I think.This vidio is in Germany but came from USA .Alot of thought and time has gone into setting up this one i think.
Diese "Ja leck mich doch"-Umdrehundzurückgeh-Reaktion? Die zu sehen ist noch fast besser als das Teil selbst :D Der Kleine tut mir dann doch aber irgendwie schon ein bisschen leid...
haha you're just waiting for the curious guy with the umbrella to go OHCRAPNOISE! very nice build but you should probably use some thicker steel on at least the choke cone. it's vibrating like mad in this vid; it won't last long like this.
