............... if only !

What I object to is the crap bolt on alloy supplied which hardly alters the sound at all ... and then if you want proper silencing - you have to go to a 3rd party supplier and pay ridiculous pricing that is near same as you pay for your car silencer !!

Note I am not talking about ones just redesigned to fit particular cowls .. ie Pitts etc. - I am referring to silencers that actually silence ! Few and far between I might add.

Added to the diesel engine efficiency is the lack of a carb butterfly. Gasoline engines use a butterfly in the carb. So the gasoline engine is pulling a vacuum in the intake manifold while running at light loads. That's a vacuum pump, and running a vacuum pump takes energy. The diesel engine has no carb butterfly, and is more efficient at light loads.

These gas warbirds are from Germany and you can beat the sound of some of thos gas radial motors they are running .

Wow! I really like that engine. More, I wish I could fly like that.

He flew that flight on that small gas tank so how many hours of flying time can he get on a gallon of gas.

Now I could kick myself for selling a few of my glow planes. I could have just changed the engines out. Horizon had this video on flying time.

Or, putting in a modern high power brushless motor set up.

Electric is great .... but having had the 15cc RCGF - my wet-fuel passion is re-lit.
