Sorry, I've been all over the country lately and I guess I forgot about that!

Here is the installation I'm using: I lengthened the throttle arm with a DuBro servo horn. I don't know if it's really necessary, but I wanted a little more clearence for the choak pushrod.

I cut about half of the threads from a pushrod, screwed a nylon ball cup onto it and bent the wire as shown to clear the tank.

Then I mounted the servo to the receiver mount (You'll need to cut the servo opening and add doublers to the bottom for the screws). This worked out great as it's now a straight line and you don't have to snake the pushrod all over the place.
