I have been thinking about a third channel needle for the gassers, I think one could be fabricated using a linkage to the high speed needle, maybe actuated with a cable, cut off the low needle to give enough clearance and use a throttle arm to turn the needle.

Your probably right Ed, I need to work on something else as I had a heck of a time adjustiong the needle on the nitro boats with it, usually takes 2 guys to get it right..
