Yes I also look for the mark and did not find it anywhere.

 I am not so lucky, mine as a Koyal 46BB ABC, and the engine was not
even 50% reliable, so I can say to you that:

	i) if the engine dies when you are at least at mid power you
can do a 180 degrees turn without any problem;
	ii) if the engine dies after you have slow down to
land then you must be carefull because the 180 degrees turn will be a
tricky one, but can be done (I did it yesterday).
