I watched his video. At some point in it he said that he'd never had a hot start in the real plane. I was astonished by that. I *always* shut it down properly but I've had quite a number of hot starts in the sim and dry motoring has, maybe, worked once and I generally only get them cleared out if I wear out the starter and replace it which takes about 4 or 5 attempts if I recall. Maybe I'm doing something wrong but I'm following the checklist. I figured I'd research it further at some point but, I haven't yet. To be honest, and I hate to say it, it's been hangared for quite a while now. If I'm lucky I get, maybe, a couple of hours at a time to sim a couple times a week and I don't want to spend forty-five minutes of it dealing with those kinds of maintenance problems.
