Adding a lightweight and even stiff Gimbal (with encoders) and a camera (Sony A7RII with Zeiss Ventum 2.8/21):

LTE range is theoretically unlimited as long as the ground unit and the air unit can reach a cellular network transmitter tower. Anything between goes via internet, so that the pilot can sit in Norway and the drone can fly in New Zealand (ok, with some latency...). The other question is, if you...

Lots of good questions! Double radio was choosen because in Germany LTE uses several different frequencies. In rural environments, typically it uses 862 Mhz for upstream which is quite close to 868 MHz and it uses much higher transmission power, so 868 MHz gets disturbed by close-up antennas...

On my H920 Retrofit I am using a pair of Zippy compact 6S 5000 mAh 25C (1338g) as well as a pair of Hacker "TopFuel LiPo 10C-ECO-X Light 5400mAh 6S" (1255g).

Better approach in my opinion is to replace the whole electronics and radio control with up-to-date standard components as shown here: Retrofit of a H920 / H920+ This gives you the flexibility to adapt the frame, which I still like, to almost any use case. In my case I will equip it with a...

Obviously you think in terms of camera drones. This platform will serve several purposes. In some applications it will carry a larger camera (Sony A7RII) with a better and lighter gimbal than the bulky thing from Yuneec, in other applications it will just carry some medical payload (1 kg) over...

If you think about updating/upgrading your H920 / H920+ to latest technology (including BVLOS capable radio control):
