 We all sometimes are over sensitized to fear of destroying our engines from
 various demons … certainly I am. But I would like everyone to examine an
 article written by Kas Thomas regarding “shock cooling” so we all are
 working from knowledge rather than wives tales on operationing our expensive
 lawn darts.

 I find them very useful for a couple of reasons.
 
 1) Expedited descents without pulling off excessive power that will shock
 cool the engine. If you fly around controlled airspace, this will happen
 quite frequently. Or what about unexpected turbulence when your in the
 yellow arc?
