There is a three cylinder, direct drive two stroke diesel flying in the
UK -
WAM120. Look at http://www.wilksch.com/
Mark Wilksch is certainly not following conventional wisdom here.

The UK also has Diesel Air's Dair-100 - a two cylinder, four opposed piston
two stroke diesel that is a near drop in replacement for a Continental
O-200.
See: http://www.dair.co.uk/

They report that they have been running at 135 HP on the dyno which, in an
optimized airframe like a touring motorglider, would make a very nice tug
engine.
