Ok, i was just looking at drones like the deepspace roc 4 and wondering if my drone could do that. Thanks for the input!

My build is currently 156g, and a 3s 18650 pack with the jp30 cells would be around 145g, AUW would be around 300g. What do you think of this for flying up mountains etc? I have a 4s 720mah and i can get about 4.5km round trip flights on it at about 7mins flight time. What sort of flight times could

you get cruising with a 850mah?

What would give better responsiveness, a 3s 18650 jp30 pack, or a 4s one? This is for a 3in drone with 4600kv motors, and i am looking to do long range (5 to 10 km) but still dive down things. Or should i just stick with 4s lihv (an 850mah maybe)?

Note: I am using 350mw analog so anything over 5km is pushing the video to its limits, is it worth having a stupidly long flight time at the cost of a sluggish quad?

@jfpoulin Do note that the rssi low warning that will show up on your betaflight osd is different, and does mean you are about to lose your radio link. Happy flying!

The radio link can go well beyond the point where you lose telemetry and it is quite nice to have radio link rssi on your osd, so that even after you lose telemetry you can keep an eye on the link. The reason the telemetry doesn't go as far is because the receiver only has about 100mw of output power(sometimes even less). If you do need more range, look into decreasing the packet rate on your radio if you haven't done so already as this will increase range quite a bit. It will increase input latency, but not too much (about 7ms at 150hz).
