So it shuts it down the same way as the nitro. The shut off button just close's the little bit of the idel that is open to keep the engine running. Then when you push on the button it does just like the nitro motors the throttle servo closes it all the way and no air no run. Right? Thanks I tried to post some photo's of my giles but I am having problems. I will get them up. Bling I like the thing you made to run the choke rod threw it is just bent wire right. Great job don't be mad if you see t on my plane too.
