All in all, quadcopters would be much better accepted among model-makers if they were a little more colorful. Many pilots say, however, that all the work building a depron body would be destroyed in a rollover. However, anyone who flies quadcopters today notices that the technology has advanced so far and so safely that (semi-)scale models can be built without problems in this regard. The only problem that arises is that there are not as many flying originals. This booklet provides design ideas for quadcopters, drones and multicopters in general.
