A successful build of my heavy lift quad copter.
Thanks especially to William Cox and Steve Keep - it is now flying a lot smoother.
Specifications:
- Pixhawk
- U8 motors
- 70A ESC
- 10S 8Ah (2 * 5S)
- 28" Carbon fibre props
- Aluminium frame
- Weight (no payload or batteries) 4.1kg
- Water resistant
- Lunch box :-)
Successful flights:
- 5 minute test flight at 12kg
- 24 minute down to 3.57 volts per cell
Issues:
- Loiter stability - everything stable except loiter
- Needs a larger box
Attached is my parameters. I read a lot about people not sharing parameters. And these need a lot of work, but here they are... shared...
In the next 4 weeks it should be flying down in Antarctica doing some radio tests to wave buoys and photos of sea ice floes.

Thank you very much for sharing!!!
I'll try this parameters and share my experiences and possible modifications.
What U8 are you using (100, 135, 170)? mine are 135.
100KV - thus the 10S :-) What batteries are you using?
6S.
Another difference is that I am using "plus" frame type instead of X.
Cool. Not familiar with X vs +, what are the advantages / disadvantages / compromises :-)
I do not know if X type offer advantages, but it was one of the changes I had planned to improve my setup, and if it's working for you...
how stable it is in Loiter with that parameteres?
