Hello guys. I want to do a quadcopter but I dont know what motors to use. Surfing the internet I found a dc motors that looks great, but Im not sure if it will work. Here the specifications:
Efficiency IE 1
Continuous Current(A) 0.1A
Output Power0.4W
Type Micro Motor
Construction Permanent Magnet
Certification CCC,CE
Speed(RPM) 55000RPM
Commutation Brushless
Voltage(V) DC3.7-4.2V
What do you think? Will it be necessary with four of them? I dont know exactly the total weight of the quadcopter. It will be composed by, an arduino uno, a bluetooth module, an acelerometer, and a chasis made of plastic

Have you thought of adding some batteries?
They might prove useful.
Sounds too small a motor - you want several watts per spindle for what you are attempting I think - you
need to carefully budget for mass and lifting power, with a good amount of headroom for control authority.
Definitely try to reduce mass a lot - Arduino mini, not Uno, for instance, you want all the spare carrying
capacity for the LiPo battery.
Its important to match propellers to motors correctly - without full specs of the motor (at the very least
motor constant, max torque, winding resistance), it would be guess work - find existing experience in
sizing multirotor craft (RC model forums are a lot better than hear for instance).
BTW why didn't you include a link to the motor you describe?
Search for "7mm or 8.5mm coreless brushed motors". That's what most small quads use for direct driving a small prop. They will use 1-2 amps when under load.
You will make about 20-25 grams of thrust with a well suited prop and a 7mm coreless motor. Try and keep your total power system/frame/motor and battery under 50 grams.
