Please explain how some Swedish guys have a 300C up and flying with a diesel. Pilot mag about 6 months ago. A modern diesel engine is close to 75% thermaly efficient, is pretty light and produces a serious amount of torque.
Compared to a 1930's engine - eg HIO360D1A in a 300C which is very expensive to run and maintain.
Lets face it we have put up with rubbish engines for way to long. I have recently been training the owner of one of the big GB rally teams. You should see his face when one explains the finer points of a Lycoming and Magnetos !
A question for all you piston rotorheads - if you spent £ 15000 on a car would you expect it to use 1 litre of engine oil every 4 hours / 300 miles ? i would be taking it back to the manufacturer, The Dept of Trade and Industry would be sueing over " not fit for purpose " But us aviators will spend £15000 on overhauling the lump of Cra_. !!!!!!!!!!!!!!!
