RE: fuel shut off valve?????
Hi Synthetic,
I make a small ply plate, attach the Festo Tap with a bracket (I think I got it from Dreamworks), and attach the servo with good servo tape. Drill a hole in the wheel to fit a 4.40 bolt. Make it just far enough out to touch the tap near the end.
It does not need to be aligned perfectly but try to get it close.
The pics should explain it all.
You can turn the tap on only by hand, but you can turn it off with the servo or by hand.
I use a Hitec servo so I can set the end points. I guess you could do it just as well with the radio.
I attach the plate to the side with velcro. This is in my Turboprop Extra
Regards
