I've only been in this hobby for a little over a year and I'll admit that I don't know everything. I may pretend, but I don't.
A fairly common noob question is about KV. I know as a general rule, the lower the KV, the bigger prop the motor can handle.
But I was wondering, is there a general rule chart that shows more specifically how much KV you should have with any given prop size? At least prop diameter?
It probably depends on motor size, but as far as I can tell a 2000-2200KV motor is good for 6x3 or 5x5 prop. 1300-1500KV is good for a 8x4 prop. And 1000-1300KV is good for a 9x5 prop. But is that only for "park fly" sized motors?
I'm considering doing the research to make such a chart. But I don't want to waste my time if one already exists. I did a quick search and didn't really find anything. It does sound like motor size matters, but I think that motor size is more about how many cells the motor can handle and may not have much to do with prop size.
So I'm thinking a chart that lists specific prop sizes with the recommended KV, number of cells, and then approximately the motor size.
To research this, I plan on looking at a ton of specs for different motors and use that as the raw data.
I think it would be incredibly useful, not only to me.
