Due to very limited space constraints, I’m leaning towards buying a Pixracer R15 for my traditional 450 heli. Questions:
I plan to use QGC software. On the firmware issue - Does it matter if I load the Pixracer FC with PX4 or Arducopter firmware if both are offered during first set up?
I plan to mount the FC 180 degrees (roll axis) from standard mounting (upside down, gel or foam mounted (with safety zip tie loosely placed) to the bottom part of the heli frame. IF I do all my initial orientation calibrations with the FC in the aircraft…do I still need to set the QCG parameters to tell QGC that the controller is mounted 180 degrees (roll axis) from standard…or will the software pick this up during my orientation set up phase of QGC set up? Any other things to be concerned with?
Does anyone know if Pixracer 15 has the voltage step down circuitry built into the board to run the 3.3v Spektrum Satellite receiver? The board DOES have the physical satellite port…just not sure if its stepped down to the correct 3.3v. Is it OK to use the satellite receiver as the ONE and ONLY receiver for this small-ish heli or am I courting disaster?
