Will this drone fly?

Put in the motor, prop, ESC and pack you are thinking about. It works out the thrust, the current every part has to survive, and whether the combination makes sense before you spend anything.

Start from a known build

The default modern build. What most people mean by an FPV drone.

Airframe and payload

Everything that has mass but does not spin.

Four unless you are building a hexacopter or a cinelifter.

g

Bare frame only. Carbon plates, standoffs, hardware.

g

FC, VTX, camera, receiver, GPS, antennas, straps, action cam.

m

Thinner air means less thrust. Bengaluru sits near 920 m.

Motors

Stator numbers are the motor's name: 2207 means a 22 mm wide, 7 mm tall stator.

mm
mm

Taller stator, more torque and more mass to spin up.

rpm/V

Unloaded rpm per volt. KV times pack voltage is the ceiling before a prop loads it down.

g each
A each

Continuous rating from the manufacturer, not the burst figure.

Propellers

The only part that actually makes thrust. Everything else just feeds it.

in
in

How far it would screw forward in one turn. More pitch, more speed, more current.

More blades add thrust and subtract efficiency.

ESC

Usually a 4-in-1 stack these days. Ratings are per motor.

A
A

Usually quoted for a few seconds only.

g

Battery

Cell count sets voltage and therefore rpm. Capacity and C set how long and how hard.

Chemistry

The default. High current, modest energy density, short cycle life.

S
mAh
C

Derated internally. Bench testing puts real delivery near half the printed number.
