Pixhawk SBUS support

Hi, I'm using Futaba T8FG Tx and Futaba R6208SB Rx connected to the Pixhawk RC IN port. In the Mission Planner radio calibration page all bars are grey with no movement when radio sticks are given inputs. Is there some sort of configure value to be changed in the APM parameters to activate the SBUS input or do I have to make some sort of trick with my Tx or Rx? Does the R6208SB have to be set in to SBUS mode or something?See More

Dual APM UAV

Posted on June 20, 2012 at 2:20pm 40 Comments

I was thinking about an idea of a redundant UAV with 2 x APMs, 2 x RXs, Dual Servos/surfaces, 2 x ESCs and 2 x motors. The plane should be designed so that it could fly with only one motor if needed.

The idea of functionality:

  • If something in APM(A) network fails or works…

Hi Veikko,

The camera used was a Canon 5D MarkII 21Mp 14 second exposure at iso 3200.
