Good day.

Just as I was starting to enjoy outdoor flight with my new toy, the receiver stops binding. Working fine one day, pick it up the next to find that the flashing blue light is no longer followed by that reassuring sound of electric servos. The servos are alive, but they just sit there idling. I took it to the LHS (where I bought it) and we tried binding it to the DX6i they have there with no luck. Either how, I now have to send it off to get fixed. :face

Any ideas?

Bump.

Do you guys think there is nothing I can do other than send it for repair?

Im not 100 % positive but i think when you bind it to dx6i you have to hold rudder stick over also?

i dont have to do that with mine. try binding with the TX further away.

If it is a version 2 I think you have to hold rudder stick full right till solid glow on blue light.

This, is correct its what I had to do, you can also download the manual from horizon, hobby!

Only for a non computer radio.

It will still bind without moving the rudder stick (v2). You won't be able to control throttle though. Cyclic will still work. Sending it off is the best thing to do in your situation.

If you have a V2 mCPX, there are updated binding instructions for computer radios:

I need to send my mcpx for repair but I have some concerns. I have replaced damaged parts so that it doesn't look like I have 'abused' it. Now, I added an extended boom to it, but I was much too indolent to bother with soldering those tiny wires, so instead I cut them. :roll:
I am beginning to think that this was a mistake, as it might not 'look good' to them. Will I have to get some wire and do this properly with the solder? Please don't tell me. :face

I need to send my mcpx for repair

Why?

I have broken almost every part on mine, and learned to fix it myself.

I too have repaired nearly every part on the mcp. The only things I can think of sending it on for is electronics. And even at that I wouldn't bother unless it was a main board right after I bought it on the first few flights. Servos are a bit expensive but I feel it's worth it to buy them and keep flying rather than wait for service. The main board is one that I haven't had to deal with yet and I'll probably cry when it does eventually have a big problem, it's everything on the mcp and also the most expensive part by far.

Being in Australia you are going to be without your heli for a good long time, if you can buy the parts you need I would think it would be worth the money..

Unfortunately, I am not sufficiently competent to address an electrical issue that I cannot see.

Well of course I wouldn't be sending it in if it was a feathering shaft. :lol:

This wasn't on the first few flights (maybe the 15-20th), and although I didn't cry, it was (and still) is rather disappointing considering it happened just a week after I bought it.

That's certainly not reassuring. Although in saying that, I really don't care if they keep if for a month so long as they actually stand by the warranty and rectify the fault. It's been over a week now since it failed so I have almost forgot about it to be honest, but I will not be happy if I have to pay for their faulty product out of my own pocket.

I'm just worried about not having soldered the tail motor wires. Do you guys think this will be an issue for them? I really do not want to send it just to hear them tell me I will have to spend $60+ because I 'messed' with it. I would really appreciate some advice on this.

Their customers service is top notch, Im sure they will take care of your problem but the shipping time alone is probably going to be a week each way.

As far as the tail goes, as long as it doesn't look like it can short any thing out I doubt that will be a problem, ship it to them with the tail off if you are worried about it.

You mentioning messing with tail wires, and electronics going out sounds VERY familiar to what happened to me. Its kinda common from what I can tell. If the two wires going to the motor short somehow, it can cause the FET (whatever that actually stands for I donno, I just know they're cheap and it was easy to fix) to burn out. When this happens, things don't work right. For me, the tail motor was just full on constant and the main motor kept cutting out.

I got the digikey part, soldered it on, and it fixed my problem.

Might or might not be whats wrong, but its an idea.

+1 Touching the tail wires together can burn out the FET on the board pretty quickly if current is being passed. I've seen the usual failure mode is to just fail on and run the tail at full. I haven't seen the FET drivers go poof though which is nice (main cause of all the CC HV failures last year).

Like Airman noted, it's a fairly common part available at any number of SMT parts suppliers.

Those guys are whom to contact for warranty in Aus. It's a long road though. If you bought it from a LHS contact them, or likewise if online (and in Aus).

Depending on the issue I can probably fix it for you.

Send me a pm with more detail of the issue if you want.

Yeah, that's them. They are in Adelaide. Also the same place I am to send my DX8 to if it need be, so I better hope that they're good to deal with. :lol:

Cheers.

Well it's good to hear that you think they are good. A week or two is nothing. Like I said, I have almost forgot that I have an mcpx, partly because I have been very busy. I won't send it without the tail because they may suspect that I have broken it.

I did the boom extension (cut the wires) after the board failed... how could it short?

And from what I hear, I doubt that the issue is with a Field Effect Transistor. For all I know it may well be, but I cannot know because the problem is that it doesn't even get pass the binding phase. The blue light just keeps on flashing indefinitely, and I do not even get control of the servos that just sit there humming.

I had a look at OMP's website for their phone number.... they don't have one. :hammer

I had to leave them a written inquiry. I am awaiting their response.

Seriously?

I demand to know the source of your intel. :) Do you work for them?
