Thank you Martin, Pascal.

That's exciting stuff. Excellent news.

for now the idea is to have a (USB) joystick/gamepad connected to the
gcs computer that gives commands like setting an attitude (auto2.1) or
maybe more sophisticated like direction/altitude (auto2.2) to the
aircraft. This will be an addition to the classic transmitter PPM
control (hence auto2.x) which remains to have priority and be the main
source of control and trim.

Another interesting thing could be force feedback giving you info about
system messages or the aircrafts flight attitude.

Completely understood what Pascal was saying. I guess my point was
not quite understood.

My question was if there is going to be some new way to trim out a
new aircraft. I can wait. I just figured since he brought it up maybe
we could get some more details.

I guess Pascal means the joystick is connected with PC or some black
box and send data through modem instead. That is what Procerus did.
They have a black box with modem and joystick ppm interpretation
circuits in it (I guess) so that u can set up all your trims in your
ground station software. But I am not so sure if the joystick can
still control the airplane without a PC.

With only a Joystick at the ground station how then is a new
aircraft "tuned"?

My understanding is you must set mechanically all the flight
surfaces properly for stable flight before AUTO2 is possible. With
only a joystick is it possible to fly a model in "manual" or AUTO1?

Hi Christophe,

this is currently not possible since the RC link is the a safety
link which gets priority over the autopilot. The simplest way for you
would be ... to get rid of the RC receiver. If you want to keep it,
you will have to patch the lines in main_fbw.c from line 119 and 127,
to disable the RC handling on the desired condition.
We are working with Martin Mueller on a way to control the aircraft
with a joystick connected to the ground station. It would provide a
kind of AUTO1 mode inside AUTO2. Probably some news about it soon ...

Dear List,
We would like to disable any manual or auto1 mode when for instance
when dist_from_home is larger than 500m. We have a lot of model
aircraft clubs in the vicinity and absolutely want to avoid that a
perfect auto2 flight is hijacked by accident.
I was wondering if there is already an implementation that fits in a
flight plan (exception cond="dist_from_home>500" set="mode" val="
AUTO2") or if anyone is already using this kind of rule?
