 > The IBIS plane has been designed for use with VW (Volkswagen) engines in
the 60 to 80 HP range, i.e. engines of at least 1830 CC or any more

powerful

VW engine. Any four stroke four cylinder engine, without reducing gear,
weighing 75 kg or less, in    good working order (and roughly equivalent to
the VW or up to 20 kg lighter) presently in use or coming on line, can be
mounted on the   IBIS.
 >     It is also possible to use the French engine "JPX 4T 75A" 80 HP, the
German "LIMBACH 2000 EC" 68 HP or Australian "JABIRU  2200" 80 HP. All of
these engines are without reducing gearbox.
 >   A two-stroke engine is not recommended as its specific consumption is
much greater than that of the four-stroke engines.
 > Some  rotary engines can also be considered as alternative solutions.

The

65 HP Continental engine, on the contrary, is too heavy and too   bulky.

I looked at it again and I think these people are talking about the Moller or
NSU or Outboard Marine little rotary with air cooled rotors. These are not
available in the Moller case and hard to find in the others. Even a single
rotor Mazda based engine will be too heavy. If you know a machinist with time
on his (or her) hands, you could build one up with aluminum end housings.
That would get you closer.

Does anyone have a fairly accurate weight on a 12A, and 13B bare block assy?
Paul maybe? No accessories or flywheel.
Royce

190 pounds for the 13B. Don't know what it is for the 12A
