Motors 450 heli KV?

[D.O.G.]

Hey everyone! I'm in the market for a new motor to run on my Tarot 450PRO V2 FBL but i don't really understand what KV should i run? Some motor has 3850KV, 1700KV, 2700KV, ect. I just want to have an idea before i buy a motor. Right now I'm running HK 450 / KV 3500 with 45 amp yep and it works so far i think? Some say 1700KV is enought? Need some input "411" before output "$" Any thoughts well appreciated.

If you are running 3s, then you want to run somewhere between 3400-3600. I would opt for the lower such as the Align 450 motor. But, if you are runnihg 6s, then you will need something lower like the 1600-1700 kv. Check out my video below on how to understand motor kv and matching everything up.

3400/3800 for 3S
1300/1800 for 6S
The pinion will make a big difference too.
