Re: Multiplexing multiple switches to one RC channel

It sounds similar to the 6 way switch which is already implemented in the GUI. The difference is, that people use an analog knob instead of many switches. Or they have a TX with a 6 state turnswitch. The benefit of using separate switches is, you don´t have to go sequentially through all states, whi...

The point is to eliminate the need for a separate channel on the TX, regardless of the way your retracts work ( servo or servoless).

retractable landing gear automated

Hi Folks, more and more frames come with retractable landing gears. Instead of using a separate switch on the TX, it'd be nice to fold/unfold it automatically by baro/sonar/land-switch . The SW would need a threshold ( say 5m above ground ) and maybe two variables for top/bottom servo angle. What do...

Re: Mega Hardware PWM Servo vs Motor

My best educated guess is that some servos can't handle the signal without prescaler.
If I understood correctly, the prescaler makes the timer count slower, which might have an influence on the loop time. ( e.g. prescale = 16 => refresh servo every 8th loop. )

IIRC, you can set 250+ WPs in the mission planner. Taking into account, that each WP has to have a minimum distance to the others, you would need a very huge battery ( long flight time ) to hit the limit of megas internal EEprom.
Why would EOSBandi bother to write a code for a specific FC?
