Ok I'm building a TopFlight Gaint P40 with DX8 and AR8000 reciver

As we can't use reverser Y my elevators are going to take 2 Chanel's

Now I Run a Kill switch on almost all my gassers.
But on this one I was holding to use a servo on the choke so I don't have to go throw the head ack of tring to figure a neat way useing 4-40 rod to pull the choke

so I have been thinking of 2 options.

No kill switch and use that Chanel's for a servo to close the choke for starting and emergency ststoping

Or is there a way wire in a servo with a 3 way switch that I can flip while power is on so I flip the choke on and off?

thanks<br type="_moz" />
