Yes this may go outside the original topic. But when pondering 2-stroke engines, you should not concentrate on single details. You are so correct saying how simple it looks but in reality there is very complex interaction between all those simple details going on when engine is running. The magic word is harmony.
I am quite sure that the amount of air going in is not far from calculated value. Of course there are some losses but not so big as elsewhere in the system.

Hi Laurie,
           I really can't see that the amount of fluid inducted each stroke will ever equal the swept displacement of the engine.

Sure if you had a Wide Open Throttle with a ram air intake as found on a speed model (suggested above) you might approach it as a theoretical maximum but in stunt use we are far from that with maximum performance way down the list in favour of a more 'draggy' fuel draw.

Are you suggesting that no matter what size venturi (or indeed any gas induction passage) you use that they all will allow an almost 100% fluid draw?

Outstanding!  Those things will fly, in the hands of a competent pilot.

 AWESOME!!! That's the first time I've ever seen a Cox Stuka actually fly, and not too badly either! I was amazed at the landing too, I figured it would drop like a rock. Nice job and neat story Dan! y1

 Just curious, what size and length lines did you use?

I'm sure Grandma and uncle Jimmy were watching proudly.  Looked really good!

Heartwarming for sure Dan Dad and I shared an intro to control line with the exact same plane. Dad took it off straight up and down she came to smash into bits. All I remember is my Dad running backwards. We went out for BBQ and homemade ice cream after. Saw my Dad turn into a 14 year old boy that day. Changed my life.
I did want to see the bomb drop...
Nice Dan.

You flew those planes. You'll have to clean them really good before you apply the vinyl.

I'll have your stuff in the mail this week.
