A large jet engine tested up to 20rps (can take more but the pid might need to be tuned again), to use it you need to send your throttle output into the pid's "setpoint" input, you will also need to send on off/off signal in the pid and the jet engine microcontroller to turn the engine on and off and you can connect to your fuel source with the pipe at the top of the engine.
The battery included is meant to be used only to start the engine and will recharge with the turbine electric output, i added 2 small generators, use these instead.
Hope you guys like it and if you have any feedback feel free to post a comment :)
