To fix ATTI alarm, this is due to missing barometer. No problem, just go to Attitude / Settings / Attitude State Algorithm and select Acro (No Sensors).


Output is more tricky, as you need to use System tab and change

Settings, Actuator Settings and set BankUpdateFreq to 4000 for banks 1 and 2
Set ChannelMax to 250 for channels 0,1,2 & 3.
ChannelNeutral to 10
and ChannelMin to 0. (all for channels 0,1,2 & 3)

Note: if you go to Output tab and change something there, this will probably mess up the settings, as this page is not really brushed-friendly yet.

With this settings you will get 4khz PWM switching speed, which can be annoying, but this is best thing for the moment. The problem is that with classic PWM, timers run at 1Mhz only, and for 4khz switching speed maximum period is 250uS with resolution of 1uS, gives 250 levels.. any higher speed would degrade resolution.

The high frequency PWM is definitely the problem separate from F3 support and will be addressed as such, hopefully soon.

Try this but im not sure if cc3d brushed is fully supported...
