Heres a video of the thermalpulse 180-18 going through the throttle range. The advanced injector really does a good job. Its extremely extremely loud, and actually causes the ground to vibrate in quite a large area.

The ThermalPulse 180 is a valveless pulsejet designed by Beck Technologies.

A valveless pulsejet is a unique type of engine with no moving parts. Unlike ramjets, which must have air blown into them at high speed, either by a blower or by traveling very fast, pulsejets can run while completely still.

They can be throttled typically between 10% and 100% thrust in the blink of an eye, and dont require any spool up time like turbines or turbojets.

Because they have no moving parts, valveless pulse jets are much easier to own and operate than RC turbines. For the cost of a ducted fan setup, you could have your own real, high speed RC jet plane.

The truth is that by the time you add up turbojet planes engine weight, fuel and oil pump weight, the computerized control system, and any onboard starting systems, you not only have a small fortune invested in the plane, but its also quite heavy. Pulsejets can be made extremely light weight, and even valveless engines are capable of pumping their own liquid fuels by the venturi effect. All you then need is your standard reciever and servos and a small battery to power it, rather than a large battery to power a fuel pump.
