PJ8C jet engines just $299

[XJet]

Introducing the revolutionary PJ8C pulsejet for RC model aircraft.

These engines have a unique internal ceramic coating to reduce the external operating temperature and improve performance/efficiency.

They have been specially designed for the low-cost Chinese ARF Long-EZ-46 and Bobcat-50 airframes and allow would-be jet fliers to get in the air for little more than the cost of a regular nitro-powered plane.

These engines are $299 *including* airmail shipping and come with five spare reed-valves (additional valves also available).

Supplies are limited at this time.

Do you have more spec, such as weight and thrust (I imagine it's 8lb...)
My bro is making his own pulse jet too. So far, his weight 2lb and produce easily 15lb with fuel consuption of 500ml/min (gaz/diesel mix). It use a pump and therefore fully throttleable, also valve life in incredible (over 5hr). I believe his work is starting to sound like an awsome achievement.

Maximum thrust is nominally 8lbs (actually a bit more) but the engine comes with two valve-retainers which give the choice between maximum power and maximum valve-life. With the low-lift retainer you more than double the valve-life for a 20% reduction in power.

Here are the other specs:

Length: 780mm (30 inches)
Max Diameter: 79mm (3 inches)
Weight: 875g (1.9lbs)

These engines do not require a fuel pump/batteries so the specified weight is the "ready to fly but dry" weight.

Would be kind of neat in some planes that were originally designed for pulse jet.

Would be kind of neat in some planes that were originally designed for pulse jet.

I built these engines mainly for use in the NitroPlanes Bobcat 50 and LongEZ ARFs, where they fit very easily and provide just the right amount of power.

The big problem with most pulsejets is that they're either too small (Dynajet/Bailey) for modern ARFs or too big (and therefore too fuel-hungry).

The ceramic coating also helps reduce the problems of radiated heat that can make fitting a pulsejet to a traditional airframe somewhat problematic.
