RE: tubine connection diagram
hpghost,
Hey mate, I have used a servo controlled fuel cut off before in the early Wren / Reaper set up. It was fine but with todays ECU's and fail safes it's not common, although in my opinion still worth it. Once the trim hits 0 it will shut off the fuel selenoid. If you are using a digital trim for the throttle, typical with the 9X i would recommend you set the tranny to have the throttle cut on, in this way it is an instant cut off rather than waiting for the slow response of the throttle trim.
You should always have a seperate, manual shutoff valve between tank and pump!!
If you want any more info, especially on the Merlin set up or the Wren's come over to my place i live 5 mins from you site office!!
Regards
Lee
