Building this quad felt a little bit like going back in time to the era of DJI F450 and TBS discovery. I am very curios to see how this turns out and if the footage coming out of a gorpo hero8 will be of good quality without a gimbal and vibration dampeners as it was the case with TBS discovery and hero1 :).

Even if the quality coming out of the hero8 will be perfect I will still be curios to try an extra light gimbal on this setup just to see how it is two have a separate camera operator on an FPV drone.

Also it is interesting to see what flight time will we pull off with two 6s1p 4000mAh 21700 LiIon packs. I am hoping to get between 25 and 30 min while flying with an average speed of at least 60km/h.

update 14.04.2020: the hqprop 3blade props are way to heavy for these motors. While waiting for master airscrew propellers I started testing with some old DJI flamewheel 10" propellers and it flies a lot better. the hero8 video test (see below) was done with these propellers.

update 10.03.2020: tuning it is definitly not as easy as a 5-7inch especially since these motors are too small for these props. with the defaults PIDs I tried switching it for a second into Horizon mode and it couldn't keep its attitude. I managed to get it to fly decently with the full payload and with the hqprop 9x5x3 but I didn't have time to test it in any autolevel(angle) mode. The autolevel mode needs to work for GPS rescue to work since this is supposed to fly really far away. I will post DVR from it but first I want to test different, lighter props on it. I am trying to get my hands on these props: https://www.ripmax.de/master-airscrew-9x4-5-mr-propeller-set-2-stk-or.html

the good news is that even though I flown it in very powerfull wind, it had no vibrations visible on the FPV that could also affect the FC. I am very confident it will fly well after I find the right props and PIDs.
