I can't find my fish scale to get an idea of how much thrust I'm making. I figure once I either find it or buy a new one I'll rig up a test stand with the pulsejet attached to a red wagon. Then I may try out a thrust augmenter, before I fabricate up an rc boat to begin with.

Good stuff! Next time try giving it more fuel, you've barely got it idling. You can get a digital crane scale from ebay for like 10 dollars

Yeah I bought a digital luggage scale from Wal-Mart for about $5 but the thing is nearly worthless. It constantly is either presenting a final weight or recalibrating itself. My old analog fish scale was 1000x better and never begged to be thrown across the yard like this new one.

I had planned to do a few clips my static fire tests but gave up on that. I very roughly got between 2.28-4lbs in the configuration here, and 4.5lbs to 6-ish with a thrust augmentor. Got a longer video of several test runs I'm gunna upload soon.
