Compared to classic RC Blimps (multi rotors), we have reduced the total equipment necessary for reliable Blimp flight to the actual minimum. In this way, we redirected the difference in weight to higher battery capacity and stronger engines. This is an extremely significant difference precisely because strength and autonomy are key in the air. UniBlimp is closer to gliders in terms of flight characteristics than classic Zeppelins.
Stronger motors and more energy (battery or solar) produce a more reliable RC Blimp and the overall feeling of safety is much greater. The total weight reduction of the necessary equipment also freed up the available weight for the next step - solar cells. This is simply a logical advance in the development of RC Blimps.
