Seems to me there are a lot of ways to rate an engine, but what is important to me is speed and take off/ hover power.
Speed is something that can be played with forever, and is hard to measure. The power to stay in the air when you hand launch or want to hover seems to be the numbers that will do me the most good.
It will also help me make a decision on props. This stuff sure shows how just a few ounces of extra weight can crush your hovering dreams!
Seems a 23 oz plane is going to be a dog no mater what you do
Also thanks for including the rpms, I don't know if it matters, but I like to know.
Thanks again for all the readings,
