I hate to tell you guys but this is a mechanical engineering problem. You think you know what your glow engine puts out based on its displacement but you can't define it in terms of power. You might know it in terms of rpm with a given prop, but you don't know how to calculate the torque it takes to drive that prop at that rpm. Mechanical engineering is much more difficult than electrical.
Bt the way, the way I was taught, all you needed to know was:
F=MA
E=IR

Jim, how are you.
I agree that this is a complex problem. However, it can be simplifed a little.
If we had a reliable way to determine the horsepower of a YS.110
and if we had a reliable method for determining wattage of an e-motor then you could do a conversion that will get you in the ball park. You will still have to swing the bat a few times to see exactly how it works.
I wish the ''science'' were better regarding this. If I were to get into a full 2 meter setup, I would just copy What Somenzini and Schulman have already found to work, with help from Hacker. Unfortunatly, guys like that do not fly .110 setups, so we're on our own.
