Hello everyone after a long time, now iam happy to show you my mighty monster valveless pulsejet. The CC is just 3.2inches but iam sure it give good thrust(18pounds). Everbody came out of their house after i shut off my engine but really this engine is ground shaking and ear blasting. I just ran the engine at low throttle.
