Not enough thrust, help me out?

FW 450

Pixhawk Controller

2800 75C battery

GPS, Mavlink

DJI 300 ESC
DJI 2212/920KV motors

Total wieght without gimbal and camera and battery 902 grams

Battery 231 g

Per what I read it could be 1600 grams lift weight for this set up. 

Flies perfect this way no issues at all. add the tarot 2d gimbal and if flies for just a few min and looses power. Better be close to the ground cause there's not much left to land. Don't see power issues but I'm new to this.

Add the tarot gimbal and go pro at 269 grams and here is the flight log. 1402 grams it tanks and 1133 it flies like a champ. Any suggestions please. I promised my BF I could get some photos for his girls wedding. 

Oh and if I do the auto analysis of the log "Testunderpowered" object has not attribute. I thought this might be because the ESC don't require calibration.

  • Your log says you are presently hovering at around 85% throttle. It will barely fly at that high level and you have precious little extra power left over for maneuvering. You have, my friend, a flying pig.

    You didn't say what size props you were running so there may be a possibility you could put something bigger on. Also, if you are running 3S, going to 4S would make a big difference.

    So, make it lighter, use larger props or use higher voltage. Those are your choices.

    • Just make sure the ESCs and motors can handle 4S packs otherwise you'll sit with a smoking flying pig or just a dead sitting pig. 

    • Thank you very very much Tom. I'm very new to all this and that's what I thought I was seeing. I needed a  more experienced person to help. I can use that tarot gimbal on a larger frame when I build a new one. :-)
