Gents,

Engines,

The K & B Greenhead is very interesting for me.
Never see that engine in the Netherlands but Ed did use this engine before the Veco and later Super Tigre.
We see the engine on the right side in the crate! The power sourge for the Oldest Taurus on Earth.

The K & B was his champion engine I know now!

In the other threads we did write about the Os Max engines. I do use one on my MAN Taurus, a OS Max 61 FX but also the MVVS.

With cruise control, I need the best engine and the most linear characteristic in trottle position and power output,
For that I need also the carburator fuel pressure- and tank pressure controller, so I have the best fuel air ratio on any power level.
The airspeed/cruise controller activates continue the trottle position, so also in any position of the plane.
Adjustment of the mixture I do mainly by data logging of the engine (head) temperature.

Never had a dead stick with my cruise control, not with the OS Max but also not with the MVVS, both very reliable engines.

When we want speed? Maybe for pylon?

Look at this picture, a Metkemeijer, Dutch engine (2002) control line, did beat the Nelsons?

Look at the frontside! The barn door to let the air and fuel mixture in.
We sometimes do have barndoors mounted on the wings, Metkemijer did use one to let max fuel air amount in the engine.

The secret of the Metkemeijer? We always speak about (0.60) cubic inches or (10) cubic centimeters.
Do use than also CUBIC AIR and not ROUND AIR!!!!!!
Metkemijer did know it all, a real Frankie.
