Keefer is right, Fly RC Magazine is where I got it. The instant throttle response and consistancy of RPM at different stick positions has me wanting to change all my planes to this setup. If you would like, I will try to describe the hookup. Unfortunatley, the Great Planes tanks, with the two built in nipples and one nipple in the rubber stopper, are not candidates for this hookup. I am bummed, because that is my favorite tank.
