When you install the glow driver you might consider plugging it into the gear channel rather than running it with the throttle servo on a Y connector. This way you can turn it on and off at will, and if one cylinder flames out in flight at a critical time, you don't have to reduce the throttle to get the glow driver to light the plugs....if you have lost one cylinder, the last thing you need is to have to reduce the power on the operating cylinder....
