We encourage you to consider intalling an engine monitor in your favorite aircraft! A REABATE is on now till July 31 too. One hour after a recent install, a local pilot had an aircraft worry in flight and by looking at his engine moni\tor he knew exactly what the problem was! With this info he could make a firm plan easily.  He could keep flying, no need to turn around.  You will be happy with the decision making tool, and happy about the dollars saved.
