'chimba' if yr so sick of it then simply don't read it !
The technology is there to make a better aero engine that's obvious the old clunkers do the task but are way behind in many ways.
We once had piston engines in ALL planes then someone invented a better 'mouse-trap'. Just because it's been so for so long doesn't mean we can't move ahead!
It's all about cost with these clunkers. The Lyc's & Conty's are basic & cheap to fix out there on site putting anything else in place would mean far more cost due complexity.
The Porsche engine was a good Eg of what could be done with a more sophisticated engine when put in to an A/C but it really didn't 'take-off' that well as far as I can see due a few reasons, one no doubt being most don't trust 'change' as well as spares wouldn't have been in the local milk bar like they are with the old clunkers

'griffo'..........it feels weird that's for sure but it's like a big model plane to fly anyway:-)
