I usually get requested what motor measurement and KV must be used for FPV drones of sure prop measurement and LiPo voltage. There isn’t any single reply however a variety of choices you’ll be able to discover. So I made this checklist based mostly on the builds I’ve flown and seen over time, making an attempt to provide you an thought what kind of mixtures are doable and fashionable.
I believe this desk can be helpful for somebody who’s constructing a brand new FPV drone and don’t know what motors they need to/can use.
This is by no imply a whole checklist of each doable motor measurement and KV for every prop measurement / LiPo cell depend. I’ve tried my finest to provide you with as many examples as I can. If you discover one thing is lacking please do let me know within the remark. Your enter can be significantly appreciated!

Dry weight is with out battery.
Here are the definition of the phrases used within the lookup desk.
Whoops or Tiny Whoops are small quadcopters with prop guards or ducts. Tiny whoops usually have 31mm or 40mm propellers. There are additionally bigger whoops that makes use of 2″ and even 2.5″ propellers.
A Cinewhoop is a quadcopter with prop guards, usually operating 3″ propellers and able to carrying a GoPro for capturing cinematic footage.
Ultralight FPV drones are as referred to as “Toothpicks” within the pastime, that are ultra-light quadcopters constructed with skinny frames and smaller motors. The focus is to cut back weight and enhance efficiency over sturdiness.
Main focus of a lengthy vary FPV drone is effectivity and flight time. They often use much less aggressive motors and powered by Li-ion battery pack, attaining 15mins, 30mins and even longer flight time.
A freestyle FPV drone is for normal functions that doesn’t apply to any of the above. It affords a superb stability between efficiency, sturdiness, and the flexibility of carrying a GoPro for HD recording. Basically it’s only a highly effective quad that you would be able to bash round with.
