All of the elements that make up the control and motorization system are miniaturized elements purchased on internet. In the photos below, you can see the motor, which is a brushed motor « NANO GEARBOX BRUSHED » with reduction gear. It measures 26 mm long and works with lipos 1s for planes of about 20 g.
Two nano servos DYS type. They are 22 mm long and, of course, they are analog
servos operating with voltages between 3.7 and 5 Volts. The 2 identical servos weigh a little less than 4 g and will have to be connected to the receiver.
The receiver is of the Deltang brand. It is a 0.65g model with a DSM2 type frequency modulation for spektrum transmitter
The set weighs 12g before wiring and soldering the elements.
You can see on the diagram below, the various connections that will have to be done. It was not so simple, because the wires are tiny.
It’s really small. You shouldn’t tremble. Nor should you have had too much alcohol the night before, I guarantee it. These photos were taken to show you how I did it with a third hand, to solder these wires on the receiver.
Additionally, I had to prepare an additional small connector to join the battery to the receiver.
Bellow are additional pictures from the various elements and the connections to adaptors to save weight.
I weighed the whole and mass is of 12.42 g and adding the propeller the mass is just under 14 g. If we add the 9 g of the plane, we get a total of 23 g, a little higher than expected, but remaining within good limits
