Sorry I was away for so long, I was getting ready for the SE Regional Championships. I didn't clarify my first response in a timely manner and noticed that I apparently ruffled RYAN's feathers, but since you didn't post the original question Ryan, you can assume I wasn't responding to anything you had to say. LeeL asked if there was an IMAC rule, not IMAA, and I answered his question. As a matter of fact "LEEL", there isn't even an AMA rule posted in the "2004 AMA Safety Codes" that discuss such a requirement. NOW, in response to Ryan's post, I do happen to agree with what he said about it being a good idea to have your trim set to shut the engine down, as almost all competitors do, however under certain weather conditions this isn't a guaranteed method of "killing" the engine. The ignition switch, is the guarantee. The extra servo for the choke is another method, but adds a few extra ounces of weight. The best method for safety is to have your "required" caller/safety observer with you. Their primary function is the launch and recovery of your aircraft, oh, and calling the sequences can be important also. Anyway LEEL, I looked forward to meeting you in the future and good luck next year.
