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, www.powerframe.de 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.
