4mm Coreless Motor Gearbox Parts, Module 0.2 Gears, Reduction Ratio 8:45ļ¼ŒOutput shaft 1mm

Note: needs to be assembled pinion and motor by yourself

This is assembled plastic 8T pinion M0.2 version gearbox 

The manufacturer has assembled the gear and shaft

Needs to be assembled pinion and motor by yourself,  this is plastic 8T pinion

This is brass 8T pinion

The mounting hole is 1.2mm, and I feel very loose with 1.2mm steel wire, which is equipped with 75mm white propeller

The right pull angle is 1 degree, the pull-down angle is 6 degrees, and the thrust line is indeed angled

The weight of brass pinion gearbox is 1.05g

The weight of brass pinion gearbox with 75mm propeller is 1.32g

Test data, this time the 350mAh battery is charged, normal 4.35V

The thrust is about 5.29g when capturing, and the test video can be higher. Look at the voltage at this time is 3.6V, 240mA. The 4.35V battery also has a large voltage drop when using a 4mm coreless motor. It cannot reach the data of 6.5g/3.7V thrust said by the manufacturer, of course, the test conditions may be limited, because this 4mm reduction group is not easy to fix. It should be known that the test data with 3.7V or even 4V or more is tested with adjustable regulated power supply or large-capacity battery, which cannot simulate the actual use at all.
