this jet controller has everything you need to hopefully make your experience with jet engines easier c:
i will attach an example build so you can see how it all works ^^
to break it down here:
build the jet engine like normal
then attach via pipes 2 electric motors with clutch attached to the combustion chamber ( we use those for faster startup )
connect starter motors node to the electric motors and their clutch
connect the rest together and dont forget a fuel tank
important: your gas tanks need a gas relief valve with a port ^^
