SD 10 Mixing problem!
Here is an issue with my new SD10:
I fly a small Delta EPP model, called Twinjet made by Multiplex. As a delta plane, it works with combined aileron/elevator control surfaces.
In Sanwa terms itâ€™s called Ailvator, in the Futaba world itâ€™s called Elevon.
That said, the issue is:
In order to have the 2 servos travel in the indented necessary operating direction (elevator in unified, aileron opposing direction) I have to reverse the servo travel. But no matter how I keep alternating this, I always end up with , whether the elevator working upside down, or the aileron works reversed.
The only real solution of this issue would be the reversal of the working direction of the control element (elevator in this case) which is something different than the reversal of the servo travel.
Of course I tried a workaround with 2 c-mixers: 1. mixer Elevator to aileron left and 2. mixer elevator to aileron right .
This works in terms of achieving the right travel direction, BUT in this case there is no elevator trim available any more!
Itâ€™s hard to understand why.
No delta configuration available that enables free configuration of servo travel
No workaround with mixers available, as it somehow disables the necessary trim of the master channel.
I am I overlooking something (hopefully..)?
Has Sanwa overlooked something during the SD10 development ( hardly imaginable..)?
Is there a remedy at hand, or soon available?
Besides all this:
Futaba solves this issue with the provision of an independent travel reversal
of the control element ( in this case Elevator).
This should not be confused with the reversal of the servo travel.
I still own a 9z where all control elements can be reversed independently from the servo travel.
Thx for all the helpful answers.
