Spektrum Recievers esp. AR9000

[keith shaw]

I'm just curious if it's me, my luck or my karma, but has anybody else had the same experience with Spektrum recievers that I have? Here's the scenario....I bought a Spektrum DX-7 system with the AR7000 Rx and DS-821 servos to get in on the Great 2.4 Ghz giveaway!!! I also ordered two additional AR7000 Rxs in order to get two free Rxs in the "Giveaway"! I recieved two AR9000, 9 channel Rxs for the freebies.
Since that time I bought two other AR6200 Rxs on Ebay for my Trex 450 and a plank I fly. Now, cut to the chase....My first three bindings were with AR7000 and I could not get them to bind with the servos attached. After disconnecting the servos, the binding went as described in the manual. The next mornig, I set up two other models with servos attached and the binding process went without a hitch...no problem.HMMM.! What did I do different....nothing at all.!!! Today I put one of the AR6200 in my Trex and did the bind process...no problem. I take a plank and install a AR9000 and did the same bind process and it "bound" to the Tx, but it had no output to the servos. I tried every scenario you could imagine...but no success. I put one of the AR6200 in it's place...no problem what so ever. Bottom line....I've seen many posts where people recieved the same AR9000 as their freebie..so to speak. I just wonder if there is an issure with these Rxs ? Regardless, I'll definitely be returing mine to Horizon to be checked or replaced.
Just curious and kinda/sorta venting.

Does the ar9000 work with the dx7? The dx7 is only 7 channels. I thought you had to have the JR 9308 or something with 9 channels to use it.

[carlo_the_wonder_frog]

It should still work, with the extra 2 channels being nonfunctional.

So far, my AR6200 s are doing fine, the AR7000 are doing fine, but three for three AR9000 appear to bind but have on output to the servos.

You do have the little remote RX plugged in to the main RX yes? It also lights solid after the bind?

Yep! Everything is set up just as the smaller Rxs, even followed the specific instructions for the AR9000 in the manual. Doesn't matter, no matter what I do, no servo movement on any channel.

[Finless]

Odd..... You pulled the bind plug while it was still on? powered off and back on?

LOL, the 9000 is in "fast power recovery mode, I'll look like I'm binding, but I'm not"

Simple to prove, but it must be done in this order!

Turn on TX
Turn on RX (no bind plug)
Turn off TX <------- important, must be down while rx is on
Turn off RX, install bind plug
Turn on RX, wait a second
Turn on TX, while holding bind button.
Turn off TX
Turn off RX, remove bind plug

99.99% satisfaction guaranteed.


Get back to us. ;-)

Get back to us. ;-) Just did it exactly as you listed and result is the same, no output to servo on any channel. Once I talk to Horizon, considering all three of these came to me within a few days of each other, I can almost foresee a recall, so to speak. I believe something was overlooked in the mfg. process on these units.

I got the AR9000 as the free extra RX from the giveaway (bought a AR7000 as the second RX) and it worked fine with my DX7. It does sound like you have a bad batch but there are two ways to bind the AR9000 that is different than the AR6XXX and AR7000. One is with the bind plug left in the whole time and the other is to remove the bind plug before powering down. This creates different failsafe bindings. I don't have a link to the instructions at this time.

Check that the servos are installed correctly into the Rx, I found out the hard way that they turned the slots over.

IOW, where you used to have the orange wire "UP", now you have the Black wire "UP".

If the connections are to be reversed, then that is an issure that JR/Spektrum/Horizon need to address and correct. If this is the case, again, it should be emphatically highlighted in any of their publications/manuals. Also, why have I had the success with the AR7000 amd AR6200 only to have such issues with the AR9000? Doesn't make sense. I'm sold on the idea of a QC issue during mfg. i.e..tester fell asleep and several hundred got by or there were no tests conducted. Things like this can happen in a high speed mfg. environment from time to time.

[cbergen]

When I say I found out the hard way, that means I had them in upside down!! They will go, but they were impossible to get backout.....

Just verify that the black servo wire is "up".

And it was only the 9 channel that is upside down, all others are Normal.

[BruceW]

When I switched over from the AR7000 to the AR9000 I noticed the insertion and servo order was reversed as Chris mentioned but the servo slot was also reversed also which prevented me from putting the servo in the wrong way. Black wire up on AR9000 and black wire down on AR7000. I don't think Horizon is going to do anything about this since people have probably just adapted to it now.

So did you put the servo in with black wire up?

[cbergen]

No I did not, and you are right, I should have. At the very least to add in to the instructions or an addendum or some sort of warning that the connection direction has changed.

In the meantime, when the question pops up, I try to help.

i had 3 AR9000 all junk i would never fly them again. costs me over $1200 in rebuild parts

IOW, where you used to have the orange wire "UP", now you have the Black wire "UP".I have tried this way and you are correct. It works that way! Hmmm! Other than that, have you had any other issues? Don't know if I should trust them now or not.
