Is it possible to add other Q flight mode options for RCn_OPTION? Right now option 4 gives us RTL and this works great for Quadplane if the Q_RTL option is set but having QLand would also be great.
Another quick question - I am currently building a QuadPlane Tilt rotor that tilt the front 2 motors. In a Tilt setup does this free up the Servo 3 for throttle to be reassigned for other purposes?
yes, we should really have all flight modes available as RCn_OPTIONs
yes
I am trying to get passthrough telemetry (10) on my radio using the Frsky X8R receiver which has a smartport which provides an inverted signal.
In the past it was necessary to hack inside receivers or use a converter cable to provide a non-inverted signal.
I would like to know if the new SERIALn_OPTIONS parameter can perform this capability. I have tried it without success so far on Matek F405-Wing.
Only F7 processors support inversion of serial ports:
http://ardupilot.org/plane/docs/parameters.html?highlight=serial1_opt#serial1-options-telem1-options
I read that as swapping the functionality of the TX & RX pins on F7 boards - - not inversion??
What does InvertRX, InvertTX do on F4 boards?
Some F4 boards have external inverters; the PixRacer has one for UART8, but the MatekF405 has none. But the F7 processor has built-in support for inversion of all uarts.
I use an inverter cable with my F405-Wing:
On most of the F4 boards nothing…
I have a converter cable in another Pixhawk based model, but seeing as I do need another receiver for the F405-Wing, I will get one which provides a non-inverted Smartport signal, such as R-XSR which has a solder pad just for that.
Tx for clarifying.
@tridge Two Bixler 2 missions using Beta 4. One in Auto that ended prematurely; I believe due to an airframe serviceability issue rather than the autopilot. Second mission is just in FBWA including some experimentation with full flap for landing. Gusty with 11-13kts wind.
I wonder if Preflight_calibration could be added as one of the RCx_option ?
I use this function after a couple of minutes from power up to calibrate baro/airspeed after the sensors had a chance to warm up.
It would be nice to be able to do this from the remote and not have to power up laptop/mission planner for a quick test flight.
You can do this using Qgroundcontrol from an Android phone.
You will need to install Bluetooth module.
I have documented my own experience here:

BUG: With plane 4.0.0 Stable and the here2 via can the CUBE keeps in a bootloop when you set everything up and “GPS_type = 0” instead of “9”. You can not connect to the Cube then till you unplugged the GPS from the CAN port.
Side note on that, I’m not sure why “Auto” doesn’t work for the CAN Gps… at least it’s not clear from the documentation unless you dig through the Cubepilot forum.
Thanks, that is indeed a good solution, I was thinking for the case when you don’t have telemetry.
Think of Bluetooth (or SiK radio) replacing the USB cable. Note, on the F405 the battery must be connected to power the serial ports.
All the functions of the Ground station e.g. Mission Planner or QGC, work as normal including changing parameters, calibration, plus all the usual flight data.
You should be able to use the same idea with a tablet or laptop. For me I prefer to use QGC on the phone for quick edits especially in the field – although I do use MP on the laptop for initial setup.
Can you send me your full parameters? I tested and couldn’t reproduce, so I suspect a specific set of parameters is needed.
are you using 2 GPS here2 and a here ?
I agree, because 6 Modes over one channel are really weak.
But it has to be defined which channel has the priority (ModeChannel 1 to 6 or one of the
selected Mode by RCxxOption.)
e.g. already now in 4.0.0 Mode QStabilize in the FLTMode_CH and RTL in RCxxOption =4
Also a great idea, to use a lap top or tablet in the sun is not easy.
