Stock motors on mine, Walkera G-3D axis gimbal and GoPro camera. Mid Throttle set to 577 with DJI props from Banggood.

Had 460 without gimbal and GoPro.

Ive only had positive interactions with banggood to be honest. I can understand the verified cc.

After a bit (maybe a minute) the red light will flash yellow and red, and both left and right lights will flash alternately. Lift off and hover as stable as you can in one spot. After maybe 20 seconds, the lights will stop flashing, signaling that the calibration is finished. Land the quad and lock the motors. DO THIS IN VERY CALM AIR! I once calibrated in a breeze, and it resulted in a very wild ride when I tried to fly it afterwards. Good luck!
Today there was wind hovering in-house did not fix the loiter issue! Flight/trim stabilisation did not help! Must I do something else to fix the loiter issue?

I always aim to end my flights (for planes, multirotors and helis) at 3.75V per cell. The remaining energy is reserved for emergency situations.
I used 2 x 2200mah Turnigy and 2800mah banggood battery. I had stock 2700mah battery with me but didnīt use it this time.

Well i am off to see if there is room at other field so i can try automission for 150 meter high flight. :

Thanks for watching video

Props balanced? That can affect FC.

After firmware update from 3.1.2 to 3.1.5 the loiter mode is shaky, in stabilze mode it is fine (making a turn is not shaky).

Oh. I assumed you went with a full APM (2.6/2.7). I don"t believe the shark GPS module has a compass , its on the flight controller. How could it with 3 wires. I would buy a GPS+compass module and put it in the pod. There are some posts on here about locating it there.

it is apart from the colour change but there was a $200 price difference when I looked hence why I have a Nova

It's convenient for parts though

It plays it's happy song when lipo is plugged in but no mater what I do the red light keeps blinking. Have tried the throttle to all other positions to see if it was reversed but no joy.

Anyone that's installed their own rx have any ideas?

Can you put yaw own rx in this bird,
