Elvis asked for help:

I would like to get flaps, and only the flaps, to deploy for half the stick range and more flaps with "crow" for the other half of the stick range. Is there a way to program the Airtronics Stylus to do this?

Stylus Boy came to the rescue:

Hi Elvis,

This one's for the money ;-)

Actually implementing flap stick positionally activated Crow (the function you describe) is not too difficult on the Stylus.

First, you need to decide at which position of the flap stick you wish Crow to kick in (50% for "half stick"). Also you will need at least two unused C-MIXes (preferrably a third for compensation).

Second, go to the Stick Switch menu (ST-SW). Select SP after the channel (CH). Move the flap stick to the desired point that you wish Crow to be activated. Let's say the last 50% of travel. Move the flap stick down until the ST% is 50. Position the cursor of the "P" in PNT. Press the YES(+) key and the PNT will reflect the ST position. Scroll ahead and select "L". When the flap stick is pulled toward the bottom of the travel crossing the ST% point the prompt should change from "OFF" to "ON". Before leaving the Stick Switch menu, remember which one of the 6 stick switches you assigned this function to.

Third, move over to the landing menu (LAND) and zero out the CROW:L-AI & R-AI. This eliminates the CROW (aileron "UP" travel) that occurred during normal landing mode. Fourth, go to the switch (SW) menu and move to the two unused C-MIXes (let's say C-MIX1 and C-MIX2). Enter the Stick Switch number (from 2nd step) as the mixer(s) activator.

Fifth, go to the first unused C-MIX. Enter Flap (FL) for the master (MAS) and left aileron (LA) for the slave (SLA). Now with the flap stick pulled all the way to the bottom, enter either a (+) or (-) value in the % position (top, right corner of display) until the left aileron raises to the desired position. Remember this value. Move to C-MIX2 and enter the same information with the exception reversing the sign of the mix percentage and change the slave (SLA) to right aileron (RA). Now you should have just the flaps drooping until the flap stick crosses the "CROW" threshold, at which point the ailerons should then move up into crow position.

Sixth, if you have already used the two-point flap-to-elevator compensation in the MIX menu, then you will need to use a third C-MIX to compensate pitching when the CROW threshold is crossed. I'll let you guess on this one. If you are using just one point of the flap-to-elevator compensation and happy with the pitch compensation, then subtact the stick switch percentage (50%) from 100% (this is because the compensation point is read opposite of the stick switch position) resulting in 50%. Set the POINT to 50%.

Seventh, go fly the plane and observe the plane's pitch when the CROW threshold is crossed. Increase the compensation percentage at point #2 as needed to minimize pitch changes when CROW is activated.

BTW, this procedure took about 20x the amount of time that the actual programming should take.
