You're right, I guess the Flaperons are a seperate deal from the elev.
I played around some more last nite and found that I cant get the Aile to work unless the Flaperons are 'on'. Otherwise the DX7 thinks there is only one servo for both Ailerons, and the manual indicates this as well. I will experiment some more tonite to see what I can figure out. At the very least I'm learning more about my Tx.
And I'm starting to understand mixing but as a new pilot I'm just not sure what to mix and how much. I guess it will reveal itself when i get more time with this plane.<br type=''_moz'' />
Ok...
Normally only one channel controls both left and right aileron servos.
The two servos are connected to the RX via a simple "Y" cable.
However some people prefer to have each aileron servo controlled via a separate channel. That's what the "Flaperon" mixing is for on your TX.
Turn on "flaperons" and you can have individual servo controlled by a different channel.
However in addition to this control, you gain the ability to set aileron differential ( in software ) and the ability to use the ailerons as "spoilers" ( reflex ) or "flaperons"...
This is more advanced stuff so to speak, and not needed for most purposes.
The plane doesn't really need aileron diffential, unless you need to correct adverse or proverse yaw during rolls.
Flaperons are normally used to lower the stall speed, but with it's big wings, this is wasted on a Katana.
"Spoilerons" or "reflex" MAY help for certain stunts like "Elevators", or to kill lift for landings, but few people do this or need it.
I'd forgo the flaperon mixing in your shoes, and just hook up a "Y" cable.
