AR500 Rx on cessna 182 - aileron problem

[scuba-steve]

hi all,

i've just put a spektrum AR500 Rx into my cessna 182 trainer.
it is 5 channel and has 1 aileron servo per wing (set into each wing)

all is well except for the ailerons :

i set up my DX6i onto 'duel aileron wing type' and put right aileron into the aileron port sitting on the edge of Rx and the left aileron in the port next to throttle....it doesn't work...swapped them around....didn't work

i read on here that the 2 aileron ports are just an inbuilt Y connector so i put my Tx back to all INH in wingtailmix....that didn't work either

can anyone help please ??

You need a Y cable then you don't need the dual aileron on the RX. they're cheap, like this one.

Could you elaborate on "it doesn't work"? What exactly happens? You didn't give us many clues...

Do both ailerons move up and down together? If so then you can skip the Y-cable but you'll need a servo reverser.

The AR500 has dual aileron outputs. I'm pretty sure you need to be in single aileron servo mode -- the two aileron ports are the same channel. It's like the rx has a y-splitter in it.

after i have connected the battery (with 2 aileron servo plugs in Rx) 1 aileron moves up very very slowly and then doesn't move...the other aileron does nothing. this is reversed if i swap aileron plugs over.

i thought the 2 aileron ports on the ar500 Rx were an inbuilt Y connector anyway...the 2 channels cannot be programmed seperately ?
i have a reverse function on my DX6i....its not that though.

i bound the Rx with only the rudder, elevator and throttle plugged in...will that make a difference ??

thanks guys for your replies. this is what i did ;

stuck the ar500 into the body
connected elevator, throttle and rudder plugs in the marked slots
bound my new DX6i to the ar500,....using the bind plug provided and DX6i instructions
the binding (rudder & elevator) worked but ESC just beeped
followed some on-line instructions to programme ESC range...throttle now worked ok
so thats throttle, elevator and rudder working fine.

came to connect the 2 ailerons plugs into the Rx (2 aileron ports)...doing this at this point because you do this just before you put the wings on...didn't work

i've tried all sorts of things..its driving me mad

do i need to bind Rx with all servo plugs in ?
which way around do plugs go ?

[ChrisH]

You are correct; the two aileron ports are the same output and cannot be controlled independently. You should not be in dual aileron mode, rather single because you only truly have one aileron output (it's just branched to 2 ports).

If I understand you correctly, both the ports and both servos are working? Ensure that this is the case.

And you do not need to bind with all the servo plugs in. In fact, when I work on customers' aircraft I usually bind with only power so the servos don't lock up or motors start spinning.



As you can see, there is a small illustration of the wiring diagram below all the channel names. There is signal/positive/negative, in that order. Negative goes closest to the edge of the rx.

Dont use the Y cable if you have 2 servos for aierlons and go back to wingmix and set the TX to dual aierlons.

DUALAILE INH
V-TAIL INH
ELEVON INH

Dua l Aileron Wing Type Selection

Dual Ailerons require the use of one servo for each aileron and allow the use of ailerons as flaps or spoilers. This
function also allows the precise independent adjustment of up and down travel, and independent sub-trim and

differential of each aileron.

See pages 43-45 of the DX6i manual

pctekk, his AR500 receiver only has 5-channels: throttle, aileron, elevator, rudder, gear

Selecting dual aileron in the DX6i won't do anything unless he has a 6-channel receiver, where the AUX channel becomes the second aileron port.

[scuba-steve]

ok i had a result today....

put the 2 aileron plugs into the rudder and elevator ports on the Rx and both ailerons on the wings worked perfect

so its either my Tx programming or a dodgy Rx....any suggestions guys ?

[xspare]

Use the monitor function on your DX6i to check that the signal being output on the aileron channel makes sense when compared to the shifts that you see with the elevator channel.

If it looks funky you should reset that model memory and program it from scratch, clearing out any odd mixes or throws that you may have programmed. Rebind.

[scuba-steve]

it was a dodgy Rx. bound Tx to another spektrum Rx and all was well. thanks for everyones input.

Glad to hear you finally resolved it. It sounded like you were doing everything right, that confirms it!
