the distro board in a dji hex is suppose to be good for 80 amps
try 900 or 770...... you will be able to prop right. usually 4lbs camera rigs aren't suppose to be fast, slow and smooth. your chasing tail in no mans land with anything else. these multi rotors didn't just fall off the truck
most people that upgrade to 770 on flamewheels use the arm extensions and they run 11" props for up to 3.5 lbs, over that is 12"
Hey, never saw this response sorry. I could make these 1350's work but they are probably over-the-top, going to fly them soon in the SAND PIT I test everything in that way if it hits the dirt at least it's soft They don't have 900's and the closest is 1000Kv 310W. Also keep in mind, I'm NOTTTTTT a camera rig guy. I fly fast, fun, sport, camera, slow and all of the above times 10 on a regular basis. I don't want a 10lb bulky camera rig anymore than I do a 300mm Quad
I think you hit the nail on the head though, 900 or 1000Kv is probably the trick. I'll post a video of these 1350Kv's though, should be entertaining to LISTEN as much as watch lol... Who knows though, I may just make one lap around the pit and go home if it's too crazy
"the distro board in a dji hex is suppose to be good for 80 amps", they can say that if they want to but I've run double that with NO HEAT afterwards on the Hexa. Is that for the Quad maybe? Those runs in the board should be good for 100A+ sustained at 15V or so. Remember that even big building wire (6ga which is probably equivalent here to these runs) will flow HUGE current at 120VAC. At 15VDC and 100A you should see minimal heat over say 60 seconds or so. I have a thermal sensor, attached to the board and it's taped down, to the Eagle Tree OSD and it never goes above 88.1F even at 1500W or 14.5V@103A which is what I'm running now. These things have MASSIVE airflow going over them. My motors don't get warm or hot in flight, they do that after I land.
