Just to be clear, these questions are serious and from a point of ignorance (I have no experience with jetcat):

Are Jetcat thermocouples different from everyone else's K-type, industry standard thermocouples? The reason I ask is that the industrial ones are basically a commodity now and I haven't personally seen replacement ones from the turbine manufacturers costing any more than you could get elsewhere.

What about the fuel pump design? I figured there really wasn't anything special there - the motor's throttled based upon rpm and temperature, so IN THEORY you should be able to use an aftermarket one like a Flightworks pump.

Selenoids, I think may be particular for voltage and normally off condition; thought I read that here.

How about the sensors under the hood? I'm guessing a hall effect sensor using a magnet built into the nose cone?

ECU's, I know are particularly "Universal" with the mechanics of the turbine, afterall that's what home-builders have been doing for years.

Given the above, I think that it would be economically feasible to convert the Jetcat can or any other turbine can, if you replaced all the electronics, except the starter motor and pump.

This has wide application to recycling some old, but still useful turbine mechanics hanging out there.
