Fuel Line Pinch for throttle control effectiveness vs Butterfly valve

Post by Car6on14 » Mon Aug 06, 2018 6:11 pm

Greetings all,
I am planning my first pulsejet powered craft and have been doing much research on throttling. I had thought my simple servo controlled fuel line pinch would be effective, but recently read rocket mans thread on reducing air flow. This thread seems to make good sense and I just would like to know some opinion on both. The pinch seems the easier of the 2 and I have the parts for it now, but I can keep my eye out for a simple throttle body if this would be better and allow my pulse just to throttle better and last longer... I am planning to run white gas, as it seems mine is jetted for this, and it sounds like its tolerant of running lean? but in the future Id like to try running E85 gas, which would require a 1.6mm jet...?
