nano build motor help

hi all,

im building a nano drone (or buying one) it needs to be able to like 56grams and perform decently, no tricks or racing or anything like that.

im looking for suggestions for motors. inrunner or small outrunner. ideally wouldn't need to use ESC.

thanks for any help
 
You need esc's. No getting around that one. The smallest motors I've seen are
0706, the smallest I've used is 1106 racerstar. Or emax have some with plastic Bell housing. But I can't remember the size but you can get tricky with the others
Even on 2S but they can take 4S.
 
even for nano drones? isn't is build into the board? I have this drone from amazon. almost has enough power to lift 56g. although it s frickin squirelly and barely flies stable.

Micro quads aren't designed to lift anything, and sure not 56g. You'll just burn out motors. And yes, you are referring to brushed motors which connect directly to the flight controller.
 
ya I get that. im just dealing with scale, anything too big will look off, for what im going for. so id either need really small outrunners/esc's and so on or really powerful brushed inrunners. the drone I have "almost" does the job. so if I can find say 20% stronger motors it should work

I got a 3" it weighs 78g. + 4S battery = 129g.
Full fpv acro quad.
You said no esc, I just thought you was a noob thinking you could get away not having one. If its built into the board why say that.
 
Well there are a few options really... you can have a all in one with the accelerometer and processor for the FC and the transistors for controlling current flow to DC motors (brushed motors). Alternatively you could have a 4 in 1 ESC PDB that is just 4 ESCs baked into one board (like my KingKong 90GT) or can have 4 ESCs separate and typically attached to each arm on the way to the motor (brushless).

Brushless DC -> ESC
Brushed DC -> current controlled by transistors

In runner, the inside spins.
Out runner, the outside spins.

^^ these shouldn't be mixed up you can have in or out runner motor of either type just more typical to see brushless outrunner and brushed inrunner but not always the case.
