The Specification of the 6g Nano Outrunner Brushless

Item No.	1209
Weight	5.82g (0.21 oz)
Pedestal Weight	0.85g(0.03 oz)
External Diameter	￠13mm (0.51 in)
Length (without the pedestal)	11mm(0.43 in)
Shaft	￠1.5mm(0.06 in)
Length of Shaft	5mm(0.19 in)
Input Voltage	7.4V
KV	2200
Minimum No Load Current	0.1A-0.3A
Max No Load Current	1.6A-1.7A
Minimum Load Current	0.2A
Max Load Current	2.3A
Temperature	30℃
Drag Force	28g-30g (0.98oz X 1.05oz)
Propeller	30X20

Notice:
1. Only 2cells (7.4V) li-poly battery would be applied
2. Please use 5A or 10A speed controller only.
3. It’s suggested to be installed on indoor planes that under the weight of 50g.
4. The propeller can be changed according to your choice.

Test:
Propellers for testing:
1. WGS 30X20 Propeller
2. 108X68 Propeller
The total weight is 6.67g. Although it is 0.63g heavier than the first kind of sample, this kind of motor’s wire size is heavier. So it is more stable and the efficiency is improved evidently.
Power Supply and Device for testing
The voltage is chosen as 7.4V for following tests.
Insert Propeller 30X20 into the rotate axis.
Voltage: 7.4V Pull: 30.89g
Temperature: 24.8℃ Current: 0.67A Rotate: 21583 revolutions/minute
Change another kind of propeller to test.
The pull can reach 49.97g.
Change 108X68 Propeller to test.
Temperature: 30.1℃ Current:0.76A
Pull: 55.4g
We adjust input voltage. Then the voltage falls to 6.4V and the current is 0.7A. The rotate speed shows as 8775 revolutions/minute.
When the voltage is 7.4V and the current is 0.8A, the rotate speed shows as 10605 revolutions/minute.
