DJI Phantom 4 Pro

Our Phantom (lower picture right) is the common used drone for SFM data acquisition, since it works very well and reliable. With its sturdy carrying case, it is also easy to transport. Like the Mavic, we have four batteries totaling in two hours of flight time.

DJI Mavic

The DJI Mavic Pro is a small, foldable quadrotor (upper picture right). It it mainly used for filming or to take photos in narrow places. With his four batteries it can fly for two hours without recharging.


This quadrotor is an “old” one – it was the first copter for the project and crashed in Hungary 2010 due to a blocked motor. The new one has the same full carbon fibre frame made by Frank Thiemig, and is somehow improved with better motors and better propellers, now with 12″ carbon blades. It can fly with one 5000 mAh battery and a mounted GoPro up to 30 minutes. It can also carry the Canon EOS 550D, but is then limited to 15 minutes flying and also has no gimbal. But nonetheless the first important result were made with this setup.

The new quadrotor is now used for video documentation using a GoPro camera and also for narrow situations where the octocopter is too large. It also is the one to teach flying a multicopter since the frame is easy to fly and also very durable in case of contacts with the ground. It is also fun to fly it without the landing gear and gimbal, then it is very agile and fast.


The hexacopter is a larger frame and suited for heavier payloads. With its easy accessible hardware, it is also a platform for testing different things. It can fly for 20 minutes with a payload of 700g.
