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.
