To start first tease out the glow plug element, open the gas valve two turns, one-and-a-half on the needle valve then raise the throttle stick to full, then back to idle, and it initiates the start sequence.
To stop the engine hit the throttle cut function, or the trim to get to the throttle cut position. The engine shuts down, and goes into cool-down mode (blips of the starter motor until the temperature gets to around 110°C) | WREN 54 MK3 GAS TURBINE Run Time: 1380 mins running with 196 starts
