I made a table listing all the possible / popular motor size and KV for different builds. 
I think it could be helpful for looking up what sort of combinations are popular when building quads of certain size?

Most of the info are from quads that I've flown and seen, so I am sure there are missing motor sizes/kv for certain props and battery voltage.
Your input would be greatly appreciated!

huge guide, very nice idea for beginners

my inputs
i dont like the name toothpick as category, the sort of build is ultralight in my opinion. seems like the categories are toothpick, freestyle and longrange, this doesnt match for me.

for 4inch on 3s, 1306 4000kv / 110g / 650+850mah.
i hadnt the following configuration on 4inch and 3s but 1404/1504/1406/1505/1408 should work too. 3500-4500kv seems a good range.
probably these would be 4inch "toothpicks"?

5inch toothpicks missed 2204 (and lightweight 2205) in my eyes. the kv for these tiny motors need to be lowered, 2300kv-2700kv for 4s, 1600kv-2000kv for 6s. my opinion is the batteries are to big for good performance combination; i would suggest 750-1000mah 4s and 450mah-700mah 6s.

this is awesome good stuff.

Good point, i will just call it "ultralight" then.
I will add those motors to 4inch and 5inch, thank you!

thank you very much oscar! for providing frequently so much content for the community :-)

Thank you, thank you. I have been wanting this type of guide for quite a while.

Excellent.. cuts down the amount of research required.. at least for me
