Default Rudder Aileron Mixing on DX6i

My old Futaba just had a physical switch to mix aileron and rudder.

I learned to fly a real airplane in a 1946 ERCOUPE if anyone knows what that is . Some of them don't have rudder pedals.

Anyway, I haven't found the setting in my Spektrum radio. Any help?


Thanks

Mike

Just pick a user mix and mix them yourself.

Some radios have the rudder-aileron/aileron-rudder mix as a built in function.... some don't. DX6 is a lower end radio with less mixing features.

I almost bought a full scale Ercoupe in 1990... I should have.

Yes Mike, you'll have to go to the MIX screen and create your own AIL> RUD mix. You can also set how much you want it to mix(in each direction), if the RUD trim is affected by changes of AIL trim, and choose if it's always on or if you can turn it on/off with one of the mix switches. Let us know if you need help creating the mix. I've upgraded from my 6i, but I can dig through the manual and maybe it'll trigger some of my dormant brain cells!

Aaaahhhh. Which leads me to my next question.

Where is the dormant brain cell trigger ����

Lol! Ok, I had a look. It's on pages 36-38 of the manual.

How basic do you need these instructions? I'll assume you know how to get onto the ADJUST LIST screen, then scroll down and select MIX 1.

The 2 channels presented are master (left) and slave (right). Change them to AILE> RUDD. The next line is the rates. The manual shows U and D for those. Up/Down? Maybe they'll change to L and R when you select aileron for the master.

Below on the left is switch selection. The manual lists the choices here.

Then lower right is 'Trim Include'. You choose if trimming the master channel effects the slave.

Pretty easy once you do it once. Let me know if that works for you. Good luck!

Glad you got it. Oh yeah, make sure the rudder is moving the right way on the plane with the mix! If your rudder works fine from your rudder stick input, but reversed in the mix, just change the numbers in the U and D from + to _ and vice versa. I guess if you did this with the planes powered on, you'd have seen it already.

The Exponential feature is great for lessening the downward throw of ailerons while keeping upward where it needs to be. Thus keeping drag to a min.

Gadgeter,

I'm still learning my radio. Can you expound on the Exponential feature and where to find it in the menu (DX6i)

Thanks
Mike

I misspoke about exponential. Its travel adj you have to use in each direction to limit one way like down Ail. vs up
DR/EXPO has to do with rate of signal and sensitivity. Expo changes the sensitivity of the stick relative to "0". In other words it can be less sensitive around the 0 or neutral position than out towards max. where travel can be more on the surface per movement of stick. Higher value on radio = less sensitive.
Confused yet? I'll do it to ya

Looks like Gadgeter already gave as good an explanation for expo as I can give.

Your dual rates and expos are set on one screen, under the Adjust List menu, it's the D/R&EXPO page. But before you mess with that page, the 6i has separate switches for the DR's of the aileron, elevator, and rudder. I prefer to control them with one switch. In the Setup menu, go to the D/R COMBI page, and you can select one switch to control all of them. This is on page 46 in the manual. The D/R&EXPO info is on page 62.

I think if you set your dr and expos first, then put them on one switch, you'll have to go back and re-enter your info in the dr&expo screen again. So you want to choose your switch first.

I'm still trying to learn how to set up 3-position flaps on a switch with adjustable throws and slowed servo movement with adjustable down elevator offsets using my $%&* Aurora 9 system. I'm surprised nobody admonished the OP for wanting to use coupled aileron/rudder. I use it most of the time with my scale models, but it is habit forming.

Lol! Yes, where are the purists!? I've tried it, didn't work for me. It was to try to alleviate a bad adverse yaw issue on my old Phase 3 P-40 (rest in pieces), and while it seemed to work on that, I didn't care for it all the time, and I usually carry rudder through the turns to keep the tail up anyway. I found it better to use differential ailerons. But that was for me. I'm not gonna judge!

Echallenged, start a new thread and I might can help explain the mixing with limited directional throws
