After some tuning the Kratos with the YS-X6 fly's super steady and smooth, between manual and GPS/altitude lock mode we see no difference at all in stability

GPS/altitude lock is extreme good, we don't talk about decimeters but more like centimeters accuracy!!
This was with 2a3 Bf, we are curieus how it will hold up with more wind.

ESC's and motors show a temp rising of no more than 20 after a flight of 13 min (AUW 9kg)

Looks like we got a faulty batch of Radian's they are continue drifting on all the slew mode's axels, hope we can solve this quickly.

Some photo's,

Installed 8 pieces EC-2 extension cables, now it's much easier to reach the ESC program plug's for programing

ESC comparison test.

In real live the motor has to pull 1200g so to get the same rpm for the test I mounted the extra lipo under the motor.

Xoar 14x6 propeller
Plettenberg Orbit 15-24

All three tests on a 6S lipo and exactly the same conditions, only the ESC's are swapped.

Ever wondered how much silicone wire is needed to connect everything on a Kratos?

16,8 meter 16AWG (motor / ESC)
11,2 meter 22AWG (lichting / buzzer)

Nice test, what pids did you end up using with the X6? pitch and roll sensistivity around 80-90?

I guess you have probably heard that FreeFly is releasing a direct drive gimbal. It makes me want to pull the trigger on ordering your Kratos. Do you have any onboard video since you have had a chance to do some tuning?
