Hi folks,
I am doing some research on Fault-tolerant Flight Control (FTFC), and I am using my Bixler as testbed for this purpose. So I have applied splitted rudder to my Bixler and I am using 2 separate servos for lower and upper rudder sections. Do you know how I can mix one aux channel with rudder and how should I modify the code?
Thanks
Iman

I like the fault tolerant control system idea.
After seeing your post, I too starting wondering where one make the changes in the code.
In the mission planner configuration tab there are all sorts of choices for the auxiliary channels 5-8, but no rudder option.
Looking at the Arduplane sketch there are library files called RC_CHANNEL .cpp & .h , I looked at those files with windows notepad but it's difficult to read because the lines all run together. Arduino won't load those [.cpp & .h] files & I don't have visual studio installed.
One of those library files could be modified to make an Aux channel "shadow" the rudder output. (I think)
I personally do not know where best to modify the code however.
One of the project developers would know how to do this.
The changes necessary to the APM code should be pretty straight forward for someone 'in-the-know', however things may get a bit involved if the servos operate reverse from each other or if the control throws are different.
Another way to accomplish this would be to use a Y-cable on the rudder channel, not very exciting though.
If you were just going to test the feasibility of the split control surfaces without an autopilot you could bind two RX's to the TX , power the RX units separately and they could each control one "set" of the split control surfaces.
Lots of possibilities....
Like it, I was thinking in a similar setup in order to have a manual control everytime, because i lost 3 airframes in APM issues.
Could you explain the purpose of a split rudder?
