I've seen a lot of excu - er - reasons. The valid ones in my mind are the field conditions. And at contests, fine. This may sound harsh, but if your engine won't idle slow enough to land, fix it or get a better engine. If your tailwheel won't let you steer properly, fix it. If your model noses over easily, change it. If it's too weak to simply taxi, build it stronger.

Some big negatives to shutting it off. If you hit a hard gust, you can't power out and save the model. If you shut off, you have limited your options in case something happens and you should go around. Like somebody taxiing out in front of you. Happens all the time.

Frankly, I more often have to wait to land because a pattern model was shut off and the owner has to go out and get it. This is radio control!!! Land and taxi back just like every other RC model.

Just an opinion guys. I do have good fields to fly out of.
