| Subject: | Re: Bracket for the mounted solid state ignition |
When I was building my plane I didn't like the way the ignition was
mounted. My concern is that the cantilevered mounting can let the module
vibrate. What I did was to put a plastic threaded pipe plug in a
threaded hole under the module. This keeps the module and bracket in
tension so it cannot vibrate. So far 150 hours and no cracks.
