T-Rex 800 Pro DFC Params

Posted by Jochen Anglett on April 21, 2016 at 12:59am

anybody out there how can help me with some good PID Values for 3.3.3 to start?

My first two attempts were unsuccessful and that could be very expensive. If it's a secret, I would be willing to pay for it (Paypal) :-)

Mechanic: T-Rex 800 Pro DFC with stock components.
FMU: Pixhack from CUAV
Software: Arducopter 3.3.3

The mechanic is built very well and was also in the air with a Skookum Robotics SK720 GPS and a DJI Wookon H. I have also built a few small and large Multicopters with Pixhawk, but it is my first Helicopter with Ardupilot/Pixhawk...

Many Thanks!

JOA

      Hi Jochen,

      are you from the CUAV team? I have followed a discussion and seen a video about such a configuration...

      No, I am not from CUAV, but Tridge from CUAV eliminated the bugs from the FB code.

      when the FBL works in acro mode the pixhawk can hold position or stabilize and so on? Sounds very good!

      Yes, see above

      Hi Ultrafuge,

      sorry, was a mistake with the HtML editor here, hope you can read this now:

      that's a good idea! Is it possible to fly with this combination in stabilize-mode or PositionHold? I 'm not the best pilot (have begun only 3 years ago) is Stabalize then made by the SK720 or Pixhawk? I also have a Bavarian Demon HC3SX here, so this could do the job also? What is the other possibility, do you have working Params for pixhawk only? I Think pixhawk + FBL could by a solution for my turbine trainer...

      Best regards
      Jochen

      P.S. thank you for your help!

      Hi Jochen,

      Is it possible to fly with this combination in stabilize-mode or PositionHold?

      You can use any mode with the Pixhawk+FBL setup.

      I 'm not the best pilot (have begun only 3 years ago) is Stabalize then made by the SK720 or Pixhawk?

      If you use ACRO_TRAINER=0 you can use the stabilize mode of the SK720. If you use SK720 Stabilize mode AND Pixhawk Stabilize mode it will not work as both electronis will fight each other.

      I also have a Bavarian Demon HC3SX here, so this could do the job also?

      Any FBL-unit can do the job.

      What is the other possibility, do you have working Params for pixhawk only?

      I have no ready to use parameter set for your heli, but it is easy to setup if you are a cautious pilot.
