not this time airtac. the pulse jet is a U shaped one (on a wooden frame would you belive), used a leaf blower and some burning paper to light it the first time round, this time he used a car coil and spark plug for the ignition and propane for fuel. made it back fire a few times and still waiting for the big nuclear/mushroom cloud to appear in the skies south of me. I think he said it would produce 45 pounds of thrust or was it more
still would produce the V1 sound but does not have the valves at the front of the intake.
