Solved - mCPX and DX6i Binding Issues

[Nicko82]

Hi Fellow HeliFreaks,

Forgive me if this information has already been covered before.

I purchased a mCPX v2 at my local Sydney hobby store yesterday, I wanted the BNF which they didn't have, so the shop assistant pulled out the DX4 TX from an RTF pack and sold it to me as a BNF. I took it home and tired to bind to my DX6i, the usual way as I did with the mSR and 120SR. After it bound I noticed it was flashing three pulses at a time. All the cyclic movements worked but no throttle. I spent all night on the forums and wasn't getting anywhere.

I decided to change the Throttle adjust settings from 100% to 95% also changed GYRO (0) from 50% to 65%. I then rebound it and I actually got a solid light and throttle worked!! BUT it it still wasn't working correctly, I noticed after apply full throttle and then bringing it back down again the mCPX throttle cut off and wouldn't spool up again, it was also pulsating 3 flashes again, I had to disconnect and reconnect the battery to get it working again, but again same thing over and over.

I was thinking it had to be a defective 3-in-1 controller. I decided to make a support call to Horizon, the guy was really helpful and he told me that the v2 has only been out for about 2 weeks and that they changed the programming a little.

To bind it to a DX6i or any other computerized TX you need to hold the trainer/bind switch and hold the rudder stick to the RIGHT at the same time and then switch on the TX.. I did exactly that and It worked!! Everything was working correctly with the documented DX6i factory settings.

The guy also mentioned that to bind to then no-computerized TX the rudder stick should be held to the LEFT instead, you see Horizon does have a video describing how to bind, but only to a non-computerized TX. Anyway I hope this helps and I wish you all a Happy New Year.

I glad it worked for you but.......

That's not what the manual says......

The manual specifically says to press the bind button while powering on the Tx......

After 2 - 3 seconds, release the bind button.......

Only then do you apply full right rudder......and you hold rudder until the blue LED on the 3-1 goes solid.....

This comes directly from the addendum to the V2 manual, as the bind procedure for a V2 has changed from that of the V1.

I agree with you totally, which is why when I spoke to the Horizon support rep, I specifically asked him "Do I press both at the same time?" he said yes and I did it while on the phone and it worked perfectly, I will try the way the manual describes tonight and see if that works.

Np.....always ask a tech rep.....if he/she has performed the actions that you inquire about...

The results are in... so of course the method mentioned in the manual works but it has to be timed correctly, I found that out of 5 tries it didn't work 2 times because I didn't time it correctly. On the up side it actually works perfectly fine doing it the way Horizon instructed me too, so handy to know for other that struggle with the documented bind procedure.

I'm just about to buy a 6i for my mCP v2, so I really appreciate you posting this,

Your welcome SuperBee, Now I know for sure that the documented binding procedure is confusing for others. I walked into the hobby shop 2 days ago, and there stands this guy with his son, and he is arguing with the shop assistant, insisting the mCPX is faulty because the throttle doesn't work. The shop assistant told sorry we have to send it back for repair, so I couldn't help but intervene. I told him that it most likely be a binding issue.

At first he got really defensive, and said "No! binding is fine, see look here, all other movements work OK" I just asked him if I may, can I try, so he handed it over, he also had the DX6i but in mode 1. Anyway did the same thing, I held the trainer/bind together along with holding Right rudder and stood back about 4 feet and powered on the TX and VIOLA! The guy was really appreciative, and the shop assistants seemed embarrassed and took off. So it seems Horizon need to update the documentation if there is a binding alternative, besides they were the ones that instructed me to do it like this in the first place.

Good luck with the DX6i, let me know how you bind it..

Your timing is now "poifect"...

Tried and failed numerous times by doing it as per the instructions (waiting to do the rudder til after the trainer switch was released).

Then tried it per Nicko82's instructions, and it worked perfectly. Just for grins, I re-bound it several times this way, and didn't fail to bind one time.

One thing to note: the LED on the 3-1 board might go from rapid flashing to slow flasing for a few seconds before it goes solid. DON'T LET GO OF THE RUDDER UNTIL AFTER IT GOES SOLID. If you let go while the LED is slow flashing, you'll have to start over.

Thanks! Worked like a charm.

[red_colt]

thanks for the post...had the same problem and thought the controller is the problem.
after reading this, i'm a happy flier.

i hope this gets posted somewhere important like a sticky.
thanks again N82.

Glad I found this thread. I build a DM8 module for my Futaba 8FG and have spent the last 3 hours trying to figure out what I had wired wrong.

Thanks

for anyone who has a 6i all you need to do is....

plug heli into battery with TX powered OFF

While holding the Trainer switch to the up position power on the Dx6i and continue holding the trainer button as it will be beeping and the screen will flash BIND. Hold for 5 seconds or so and release. Have never missed a bind, the manual instructions are bogus.

[kurmet]

my v2 manual says to refer to the transmitter manual, and it says to use the trainer sw only this works for me

[Rrandy]

Doesn't work with the DX7 I've had off and on bind issues non stop and now cant get it bound after trying this technique and every variation of for the past 2 hours.

Just got my DX8 back from service. Service log says "reprogrammed HF unit". Bind problems similar to all of yours are completely gone. Binds at 10cm or 5m distance immediately, every time. Just like my (now sold) DX6. I had a different voodoo dance to get my 2 mcpxs to bind (at least 1m between heli and tx, releasing left/right rudder as soon as the screen goes on ...). Glad this is over now, I would suggest to contact HH, top notch service.

All this binding crap reminded me of an old CD player, where I had to tap the CD sled in a certain way to get it to play. It ended by throwing it out the window

I called HH and they took care of me, wow great service!!

My dx6i would not bind doing it that way. Spent the next hour trying to get it bound again.

I know this post is 3 years old but I'll be damned I wish this post was at the top of the thread.

I have been trying to find info on binding the dx6 ver2 with the mcpx ver1.
The mcpx v1 manual does not make any reference to hold throttle left or right during the binding process. I guess that only applies to mcpx ver2?
