Then you'll either love or hate Motocalc. You'll love it because it will help remove much of the trial and error. You might hate it for the same reason :)

That was me, not Morris.
You were talking about a 12x8 and a 12x6 prop if I remember correctly. I did expand on my statement right after, but I can do so again.
All else being equal, a larger prop takes more power to spin at a given speed than a smaller prop. And similarly, all else being equal, a higher pitch prop takes more power to spin than a smaller pitch prop. This is really common sense -- it's doing more work, so it needs more power.
However, when somebody puts a lower pitch prop on a plane because they want more static thrust, the prop they put on is typically larger than the old prop, and you didn't mention that. Going from a 10x8 to a
12x6 prop may very well give you more static thrust with similar power usage. (To be sure, you'd run it through Motocalc or test it on a plane.)
| I liked the part where he said "It'll use less power, and heat up | your motor less
Well, with less thrust being produced, using less power and generating less heat seems fair, doesn't it? :)
