Help Wanted Urgently!

Can anyone help with this one, I'm tearing my hair out here!

I am in the process of converting my Wildthing to 2.4 Gig. I'm using a Spektrum DX6i mode 1 TX with a single 5 channel RX. The problem I have is that with elevon mix active the ailleron stick operates elevators and elevator stick the allerons. I've tried swapping the servos round (ie right srevo to ele left to ail and vice versa), on the RX but it makes no difference. I have also tried reversing the servos at the TX, but still no difference.

Does anyone have an idea where I'm going wrong? Everything worked fine when it was on 35Mhz with my Futaba TX.

Disregard the servo output names on the reciever & number them 1 2 3 etc just like Futaba, then try that, the channel assignments aren't the same JR to Futaba

Mel I'm not 100% certain on this but I think on that 5 channel that the two aileron channels are basically just "Y" leaded within the R/X which may be leading to your issues. I'm sure one of the Speky users will be along shortly

Wildthings only use channel 1 & 2 so no "Y" lead required

If its an AR500 the two ail ports are effectively Y leaded together
By all means use one of the aileron channels but use a non linked channel for elevator.
Then enable two mixers, always on
Ail ->Ele
Ele->Ail

Just had another try using your sujjestion Rich but still no joy. I think Brian may well be on the right track as unplugging the servo from the elevator port causes the servo still connected to the ailleron port to operate correctly with the correct sticks in both senses. Looks like I'll have to use a 6 or 7 channel RX.

Thanks for the sujjestion Paul, tried what you said but STILL no joy. I'll order a 6 chan RX for it.

Mel I think the channel numbers on JR are 1 throttle 2 aileron 3 elevators and 4 rudder so 5 on that R/X I think will be "Y"d internally to 2

It can be done, I know Tim has it cracked so wait for his post. There is an internal link in the RX but there is a way round it.

Mel, the trick is to set it up with the elevon servos plugged into the "aileron" and "Elevator" sockets on the receiver (As you had it to begin with) and if you get the behaviour you describe, try reversing one of the servos in the setup menu.

That should sort it out. You may find that if you reverse one servo (say the elevator servo), you get the opposite behaviour to what you need (eg. with up elevator, you actually get down). If that happens. Undo what you just did, and reverse the other servo (the aileron servo).

Hope that helps.

I don't know if you can do this with a Spektrum6i Tx but you can and I have with Futaba FF9 driving the AR 500 Rx. You use one of the aileron o/p and the gear o/p(chan 5). Then in the Tx 'para' menu you change aileron 2 to CH5&6 from CH6&7. Thus, your elevon o/p's are on one of the Rx aileron o/p's and the other is on the gear o/p (CH5). It all depends on whats available in the Tx.

one servo should be in the elevator port and the other in the aileron port. then reverse and program on the Tx to get everything right, I did this with my AR500 in my zagi (elevon mix) which worked puuurrrfect, just needed a bit of sub-trims to get the surfaces flat at neutral for the trimming flight

I suggest you have the aileron servo plugged into the "wrong" aileron port on the unit.
There are, as you know, two aileron sockets - one of them will give you the mix you want, and the other wont.
So.... keep one elevon in the elevator port, the other in one of the aileron prts ( experiment with which one ) and ensure you have elevon selected in wing mix menu.
It DOES work fine...I have several ar500s in various elevon models - all work a treat.[i]

I new there was an explanation there somewhere but only being au fait with superior brands I wasn't sure

Tim, even if the servo is plugged into the "Wrong" aileron port, reversing one of the channels should sort out the response....

Got it going AT LAST! Thanks to a combination of Tim and Andy's sujjestions. Many thanks to all those who posted answers big help.

Glad it is sorted Mel
