Hi, I would make a small drone and I decided to use these motors:
What mosfet should I use for control them?
Can I use this module?
Find some motors with actual data, might be more successful! You need to know the rpm and
torque to match motor to props.
That kind of motor is a coreless brushed motor, there are many available. You need to find
a motor/prop calculator online somewhere that works for microcopters.
That MOSFET is hopeless, it requires 10V gate drive and is high voltage device!
Since those small motors take at most a couple of amps at 3.7V, you need logic level
MOSFETs, 20 or 30V rating is plenty, and on-resistance doesn't have to be very special, 0.1 ohms
or less. Most devices at this kind of rating will be surface-mount, note, but you'll need surface
mount to keep within your mass-budget anyway.

So you have no idea what mosfet to use for those motors?

I don't follow you. MarkT gave you plenty of information to use for selecting a MOSFET.

I have absolutely no idea what MOSFETs fit that spec, but if I wanted some, I'd use my
favorite electronics suppliers website parameteric search engine to find candidates. There
will be a few thousand parts that match, not something anyone would ever memorize.
Its not like the 1980's when the number of devices available was a few dozen, there are
literally 10's of thousands of active MOSFET lines available. By the time you memorize
a part its likely to be obsolete.
If you want to drive several small motors like that you'd probably benefit from getting SOIC8
packaged dual MOSFETs. Don't forget freewheel diodes either...
