[tps_title]The required hardware[/tps_title]
When building a quadcopter from scratch, the choice of the materials becomes an essential subject, to which to pay the greatest attention: each component must interact with all the others in an entirely perfect way and nothing must be left to chance. We oriented ourselves towards common components, and not excessively expensive ones, that are distributed by the our online store. The list is in Table 1. As an alternative to the FTDI converter, you may use the 5V FTDI USB-Serial, labelled with the 6168-FTDICABLE5V code, and still sold by Futura Elettronica.
Table1
The propellers used for our multicopter’s propulsion are of the simple plastic kind: they are the cheapest ones; their light flexibility enables them to absorb small shocks, at the price of a lesser efficiency. The filled plastic propellers (such as the APCs, for example) are more rigid and offer better performances; those in carbon are very light and rigid, and are however very delicate, since even a small shock may break them.
We would like to remind you that the quadcopter absolutely must not fly if a propeller is cracked or chipped, and anyway that you must never try to repair a damaged propeller, since a part may detach itself and hit someone, with the resulting consequences that might even be serious ones.
