If you have 20 micro motors and you know it clap your hands!
below are the specs on this type of motor:
http://www.us.diigiit.com/chaoli-cl-0408-coreless-motor-4mmx8mm
This motor is one of the smallest we carry and can be used for really small robotic applications like a small UAV. Despite its small size, this coreless motor is very powerful and can easily be used with a small tail propeller like the one we sell. This motor is rated for 2.6 V. By connecting the red wire on + pole and blue wire on - pole, the motor will turn clockwise.
Features
- model: CL-0408
- shaft diameter: 0.6 mm
- body diameter: 4 mm
- body length: 8 mm
- voltage: 3 V to 5V
- nominal voltage: 2.6 V
- cable length: 30 mm
- weight: 0.5 g
- torque: 0.08 g.cm
- no load speed: 42000 RPM
- no load current: 35 mA
What this means:
so all 20 motors are 10g weight. and pull 850mA for 10
So I might get 25-30 with a 450mAh Battery? This will have 2 servos for control surfaces. which draw 100-150mAh average... so 1.1Ah
If I have to, I can always use 0820s with whoop props... size goes to a 60-70" wing. si 6-8 mins with a 150mah... something seems off...
There is no data on Amperage if it has a prop though.
