Thursday 25th and Friday 26th of September 2015 was the International Drones Exposition for Civil Applications, ExpoDrónica at Zaragoza (Spain).
Expodrónica has been the first exhibition of its kind to be held in Spain aimed at professionals involved with Drones. The International trade show has featured more than 80 exhibitors and about 3.000 visitors.
Expodrónica brought together the whole range of professionals involved in this business such as producers and manufacturers of applications in mapping, agriculture, gas emission measurement, land and urban planning, civil engineering work and film industry.
I attended it as visitor and found really very interesting things. The first thing I found was the increase of platforms available from different manufacturers from Spain.
Because of my daily work as Multirotor Systems Manager at IXION Industry and Aerospace, I have good relationship with lots of companies in the sector, both manufacturers of rotary wings as well as fixed wing equipments, like Dronetools, Aerotools, Usol, Inda,... It was nice to see them all at this event.
Mainly they were rotary wing drones at the Expo, both professional and hobby grade. Even I saw an impressive race between some of the most recognized aerobatic drone pilots in Europe. Those drones had peaks of speed of 120km/h!!
In the professional sector I found very interesting platforms. I noticed more and more a tendency on taking special care on the design. Up to now, we were used to see drones with lots of cables going around the core. Here I found most of the professional drones with smart designs, able to support rain and using folding arms, a very important characteristic in professional drones, that use to be quite big. There is nothing more terrible than a case, so big for storing a drone, that you need a truck to transport it. Medium size cases with wheels and hanger is what I found in these event, with folding arms, huge propellers and pancake motors from TMotor and KDE mainly. Seems that AXI motors has lost the battle, at least in Spain, by now.
Drones of about 1h autonomy is the tendency for professional equipments. Better batteries, more efficient motors with very low turns rate, huge propellers and very light carbon fiber bodies, allow this increment in autonomy with payloads from 1kg up to 10kg. Multirotors are becoming to seem more aeronautic aircrafts than hobby-pro equipments, as they seemed to be just one or two years ago.
Things are changing indeed in the multirotor drones world.
