Spektrum AR 6610 with DX5E transmitter strange connections ?

[Oldtimer flyer]

I have a Spektrum DX5E transmitter with a new Spektrum AR 6610 receiver and it all works but I cannot figure what is going on. I am using a Y harness for ailerons , rudder, elevator, and flaps on the radio switch on the left on an Eflight Conscendo. To make everything work I have to plug my aileron Y harness into channel 2 on the receiver, which should be elevator. Elevator has to go in receiver channel 1 , which should be aileron. I had accidently dropped the first receiver and I thought that was what fouled it up, and in talking with Horizon tech support they agreed. Ordered another new receiver and it is exactly the same. The strangest thing was I had to reverse channel 3 on the radio to get the elevator to go the right direction. I have the ESC plugged into 3 as it should be. The channel 5 flap switch works fine. I called Horizon again and they said it is probably because the DX5E was made prior to the AR 6610 receiver and as long as the controls respond just fly it. I am from the old school and just really do not care for a computer radio. I am 100% positive all my wiring is correct. .Any thoughts on this greatly appreciated and thanks for accepting me into the group.

I'm not a Spektrum guy, but am wondering if your radios is setup in mode 1 instead of mode 2? I think that would be about the only thing that might cause a channel shift like this on a Spektrum.

But yeah, if you got it all working, you are probably fine. Give it a ground range test before flying it.

Sorry, I got to jump in. This is a legacy mess left over from Futaba.

Most of the world had used a channel assignment of TAER (T ch1, A, ch2 E ch3, R ch4). Then the Johny Come Lately Futaba (FUBAR) used irrational* output of AETR (A ch1, E ch2, T ch3, r ch4). This really makes no difference in today radios unless you are using rx gyros, canned mixes or the RX has some kind of auto default settings.

Reading Oldtimer's post it looks like he is coming from a Futaba back ground.

*Some history, It was thought that putting the throttle channel as the first control after the sync-pulse was a good idea. This was because any noise on the pulse train would hit the least important output first and give one an indication that there was some kinda of RF issue about to happen. That is is is best to have the throttle glitch before the noise got so bad as to effect the primary flight controls.

I'm still at a loss as to why Futaba used and still uses the reverse pulse for the throttle output. This is very dangerous with ESC!

I'm sorry to learn that Horizon's tech was just interested in selling product. (historically this has not been the case). I'd like to learn how the tech thought that dropping the RX would change the RX outputs.

Back to your regularly scheduled programing.

If your 'problem' is Mode 1 vs Mode 2 there is a way to switch modes on DX5e just follow this link.... https://www.rcgroups.com/forums/showpost.php?p=39912970&postcount=6

DX5e is pretty old not programmable radio. If you stick with Spektrum, but want to save money, you can get a DX6i for around $50, BUT if you get DX8G1, you should be able to display your receiver voltage telemetry that the AR6610T is sending.... DX8G1 going price is around $100 - 125

Thanks The radio was in mode 1 when I bought it used so I did switch it to 2

Good question regarding the tech I was wondering myself Had a lot of Futaba stuff back in olden times Thanks for the input

Thank you Am considering an upgrade

Thanks I did the switch Found out how on Youtube

Was wondering the same. LOL

"Oh, they must have shifted when they hit the ground. Did you try hitting it on the other side?"

Just kidding, don't do that!
