Futaba 6XA (Field Force6) Mixing Issue

Is it possible to have both flapperon mixing and dual servo controlled elevators with this radio ? Problem appears to be that the gear channel (5) is controlled by a 2 position swith and this radio does not have the offset function of a 9CAP. Can one buy a gismo that connects into the flight pack to achieve this end? The manual seems to suggest that one can mix 2 channels to control the elevator halves, but I don't think one can have this together aileron mixing(ailerons using mixing on channels 1 and 6). A solution is to use a "pigtail" on the elevator servos and mixing the ailerons or to use a "pigtail" on the ailerons and mixing on the evevator halves, but its not a total solution. Any bright ideas would be appreciated. How about a 3 position switch to handle channel 5 ? Andy in South Africa

I'm not sure I know what you are tryong to do. I have a 6XAS, think they are the same? mk

I think the 6XAS is a later version of the set which I am referring to. Basically what I want to do is to have a seperate servo controlling the each ailerons and seperate servos controlling the elevator surfaces ( elevator has 2 halves or control surfaces). If one wants to be able to adjust the surfaces independently and electronically one has to employ mixing of some description.I don't think that this TX is capable of doing this although the manual seems to suggest it can. Howevr, the manual does'nt tell one precisely how to do this. I'm asking the group if they know of any method with this TX to achieve this end.

With respect, if I were you, this is teh point at which the Futaba would go on Ebay, and a Multplex Royal Evo go on my Christmas list.

I have a pair if FF6's because getting a second one was cheaper than getting an Evo, and it ALMOST has what I wanted...namely 6 more model memories and JUST enough mixing (I use a lot of throttle to alerion/rudder and elevator mixing which only works on full rates for some reason) ... if totally free assignment between sticks buttons and switches, and RX channels is what you want, the EVO is the machine you need.

I have never actually used one, but I understood the Evo didn't have free assignment of RX channels ?

I haven't used the 6XA either, but I just dowwnloaded the manual from and it definitely shows V-Tail and Flaperon mixing. If the plane doesn't have a rudder then of course you can just use the V-Tail mix with the rudder proportion set to 0%, this may not be any use though.

What is the exact problem you are experienceing with the PMixes approach ? I assume you've tried setting a PMix from ch2 to ch5 with control proportions of

100% in both directions ? Does the gear switch still affect the ch5 elevator when you do this ? If so then try setting the other PMix from ch5 to ch5 (ie to itself) with control proportions of 0% ?

It's hard to guess what will work without actuyally having a 6XA to hand, but if the worst comes tot he worst then Schulze make RXs with on-board programmable mixers, SMC and West London Models both stock these. Good but pricey...

I think the problem is he wants V tail AND flapperon..and they are not IIRC available.

The Futabas do the basic stuff (fairly) easily, though I find the logic a pain...the Evos simply throw away the concept of 1 stick=1 channel and split the thing into three logical layers..sticks buttons and switches (input devices) that feed mixers (many in to many out abstractions) , that feed output channels (one or more servos all doing the same thing, a slot on the receiver). This is more complex for a bog standard setup, but its a heck of a lot more flexible.

Once you step beyond what the Futaba thinks is what you want to do, its not worth fighting the system. Get the Evo.
