there's a fair amount of liquid fuel in the chambers on some of those test runs!

The fuel is nitro, it's supposed to run rich, but that's excessive. In the comments he says he couldn't get it to run any leaner :/
Fundamentally it illustrates the rotary problem: long combustion chamber where optimal conditions for combustion exist only in the middle-ish. The rear of the face isn't doing a damn thing.

Yes but the two spark plugs, leading and trailing of our Mazda rotary engines,do help to spread that combustion over more of the rotor face than with this single glow plug in this model airplane engine.

Hmm, I wonder why not 3 spark plugs? Cost?

I mean, the 787B 26B engine had 3 spark plugs for each rotor and it looks like the new shoebox range extender also has 3 ignition wires attached to one side of the engine.

love it..thanks for posting.

Now RE noobs 'may' get a better understanding on how, particularly engine flooding, emissions, fuel economy, etc.
And why Mazda has huge engineering problems even getting close to regulatory targets for today's 'green' world.
And I am not going to spell it out if you cant see it.

Hydrogen was and is the future for a RE powered only car, but we know why it will probably never happen.

I have one of those engines powering a little Q500 type RC airtplane.
These engines need a minimum of 25% oil in the fuel, most of it being castor oil. So that fluid sloshing around could very well be oil.
As a matter of fact, when I quickly advance the throttle I can see a spray of white liquid coming out of the exhaust before the "normal" exhaust smoke is restored: that's a stream of hot oil being ejected...
