AFAIK, the return home feature first elevates the drone to 20-30m before coming back. So if something higher is in the way this is a problem. Not sure how to avoid this, maybe the simplest solution is to increase the evelation to 100m or something like that. Or it may be possible to have...
Thanks for your reply!
Regarding the network lag, I first connected to the drone using STUN (3G devices are usually behind NAT) in order to minimize delay.
After that I tried making a simple UDP relay that runs on a server (the relay is 20 lines of python and on github), to improve reliability...

Here is a video of a 64kbps flight test this morning:
Anyone else here trying to do FPV via cellular?
We recently developed a controller to pilot drones/cars/boarts/etc via 3G cellular connection, in order to achieve "unlimited" control range.
The code and schematics are all open source and available here: https://github.com/nfco/cellpilot
We are currently testing it using hand-soldered PCBs...
