Aerobatic trainer’s configuration is that of the familiar stick model, with the wings and empennage altered to suit the purpose of this design — that of a stable platform from which to learn the basics of RC model aerobatics.
This summer, a team of researchers, engineers and a drone pilot of TU Delft traveled to an airbase in Germany for the first real test flight of the scaled flight model of the energy-efficient...
