I am thinking about having a smaller engine (say 8 hp or 15 hp) fitted as a back-up alongside my 250 E-tec, which is on order for the Scorpion (due late April 06).
I know that twin engines would normally be linked, so that one is steered and the other follows. Can this be done with engines of different sizes and with one in the centre, rather than both equidistant from the centreline?
If so, what about the power steering - is this engine driven or electro-hydraulic? If the latter, then I could still retain power steering and perhaps use the main engine as a rudder.
In such a configuration, can I keep one engine up and the other down, as I wouldn't really want the back-up permanently down?
I appreciate that there are some engineers amongst the RIB community, so I would be pleased to hear your thoughts or - better still - from anyone who has experience of this situation.
