Awsome write up Plug. Pitty I coulnd go cause the route there and back looks interesting enough let along the events.

Curious how many bottles of LPG did the pulse jet go though? Have done a bit of reading and understand that they can use a full 9kg bottle in a few of minutes. Did he get going very fast?

Cheers

About a kg per minute until the reg freezes, then it went into flame out. Started with the assistance of a leaf blower. Speed, well, just past the wobble stage. Not very fast at all. There is no corrolation between noise & speed for this beast.

I'd read about the leaf blower starting and the noise. Seems that not many people seem to be able to get them to produce much speed when attached to wheels of some sort. The Germans must have put some serious R&D into the V1 flying bombs given that they are powered by pulse jets and flew faster than many fighters of the day.

Sorry :Offtopic: I know but I've been keen to build one one day when my welding improves.
