Bonanza could be as bad as 1200ft, I guess, for a safe turnback.
This was demonstrated as 'doable'.
It is all condition dependent, and no two incidents will be the same. But as stated, a whole host of 'ifs' come into the equation.
It has never happened to me, an EFATO, other than practice, and I equate it to an S turn display I used to do in a Chipmunk where I would fly runway length, at 50', full rpm, bank up 45 degrees at runway end, into a wing over, using the aeroplanes energy. I went over at about 450', and realigned, back down, to complete the manouver at the other end. Practised it a lot, however, it was all speed and energy mgt, and I always considered that completing this was akin to a turnback.
Reactions would have to be mighty quick to achieve a result, particulary at levels under 600'
