Hello all,

I just finished my first pulsejet, a thermojet design I found in the thread "jims little 3LB thermojet". It starts and runs great, however its only producing half a pound of thrust at the most. Opening the injectors more doesn't seem to help. Do any of you have an idea as to what the problem may be? Thanks, Jake

it doesn't look like you flared the intakes. This will limit throttle range and thus thrust. Flare them and try again. It'll run a lot harder
