Hi all,
I am looking for advice from someone with experience using KDE ESC's with Pixhawk. I know from this APM page that I am to manually set RC1_MIN/RC1_MAX ... RC6_MIN/RC6_MAX to 1100 and 1900, respectively (this is a hex):
The KDE ESCs have fixed PWM ranges so you must manually set the output range of each PWM signal so that RCx_MIN is 1100 and RCx_MAX is 1900us using the Advanced Parameter or Full Parameter Settings Page in the planner.
Once I had done this, the motors would spin as expected when armed. However, I wonder if trim needs to be adjusted as well? It seemed as if the throttle was more sensitive once I had set these manual values, vs. the curve when I had simply done an ESC "all at once" calibration.
So is there a particular order this should be done, between the ESC calibration and/or the manual 1100/1900 in advanced params?
Any other advice from folks with this setup? Seems to be working, I've got a "flips every time on launch" craft but I strongly suspect that's a CG issue (two 10Ah 6S's on top, not enough to balance on the bottom yet).
Thanks!

I know it's been some time since you posted this, but I was wondering if you ever had an issue with all motors arming except for one of them. I'm flying a Pixhawk with Spektrum receiver, and KDE ESC's and motors. I have adjusted the values that you listed but it didn't seem to help. I have been at this for around two weeks now, and have ran into nothing but problem after problem. Any information that you may have would be greatly appreciated.
Issue:
I can arm the motors and once I start to increase throttle four out of six motors will begin to spin, but 2 will not be spinning. Once I get to almost Mid throttle the 5th motor will begin to spin, but the sixth doesn't kick in. Can anyone help me with this?
