Hello everyone. I was asked for help/advice directly by Elowrust via PM, but I thought I'd answer here so more people would be able to read it.
First thing I need to say is that I'm using different radio, with different software. I'm still using Tgy 9X (the "old" one) with stock firmware, so all the options seem to be different than yours. But you can still get as much from it as you can.
Second thing is my wiring: I have both flaps on the same channel via Y-lead, but the ailerons are on separate channels. Having ailerons on separate channels is required to use flaperons, since you will need to add the mixing in the opposite directions. It's not required to have flaps on separate channels though; those are mixed in the same direction.
Third thing: I'm actually not using custom mixes - it's a pain in the very bad place to make it work on the stock 9x. However I do use built-in, dedicated "airbrake" program that is combining four different mixes in one place. The "airbrake" mix is activated in the ID1 position of the 3-way switch only; so I'm limited to one flap position.
The exact setting I use was described in my very first article about the
FT Simple Storch. Here's the quote from this article:
The details of my airbrake settings are as follows:
- aileron 1: -35
- aileron 2: 35
- flap: 100
- elevator: -7
- elevator delay: 50
When the airbrake program is activated my flaps move down about 40 degrees, followed by aileron (in fact: flaperon) deflection of roughly 1/4 of it (10 degrees). The elevator is deflected downwards just a tiny bit, less than a thickness of the foam board; but this additional input makes the transition very smooth and allows the plane fly level both before and after flap deployment without touching the throttle or elevator at all.
You can find a picture showing the flap/flaperon deflections in the same article. Note: you can completely disregard elevator settings at this point. It would most likely not work the same way for your airplane, so you will need to figure out your own value and/or direction anyway. As you can see, the aileron mix is the same in value for both of them, but in the opposite direction. It is also way smaller than the flap deflection - this is mostly because using ailerons as flaps significantly decreases the aileron sensitivity. The settings above are obviously "full flap deflection"; it seems that you can use your software superiority to create 3 position flaps - something I can't do, but I believe I don't actually need.
And that's basically it. If you have any further questions, please feel free to ask; I'll be more than glad to help.
Good Luck, and Have Fun!
