i bought my HX100 and after the first r Packs i was prestty disappointet. I got two major Problems: 1. If I dive or do longer 0 throttle manovers I got washout on 2 and 3S if I raise throttle. 2. Sometimes I go down with the throttle but it keeps the ampdraw over 3.5A and doesn’t fall.
My luck was that i got help from Riddhi FPV. The trick was to update to betaflight 3.5.7 and to go props in instead of out. I also used his PIDS which you can find here https://drive.google.com/drive/folder…
Check out his Channel: https://www.youtube.com/channel/UCk3G…
After all that i can say i realy love this class of Quadcopter. They realy fly like a 5 inch but are much more harmless and quiet. But see for yoursellf
