Hello all,

i have a couple months now the blade cx 2.
Now my 4-1 was broken and i bought a new one and installed it.

The problem is i dont know how i can make contact from my transmitter to the new receiver [4-1]
the lights of the receiver flashes green and red, what must i do to let them work?

Verry friendly greetings

have you plugged the channel crystal into your new 4 in 1 (i believe its located on the top of the 4 in 1)? you just pull it out of your old one and plug it right into the new one. if you have and it still does this you may just need a new set of crystals which costs $5 - $10.

NO, he has a CX2, not CX, theres no removable crystals with the 2.4ghz system. Good explanation for those with CX's and not CX2's though, as some newbies might forget the crystals. You must use a connector to short out a plug on the reciever then turn on the TX and RX to bind one to another. I'll look at my instruction booklet when I get home (or if you have yours, LOOK THROUGH IT as it explains the "binding" procedure).

Found it online here: Look at pages 39 and 40 for directions which I pasted below as well.

Just a quick summery for the lazy,,,,, basically unplug batt, leave TX off. Short pins 1 and 3 on the BATT connector on the 4 in 1. Turn on the 4 in 1 (make sure TX is OFF). Wait till the orange light blinks, then turn on the TX (TX=Transmitter btw) (btw= by the way lol) (lol =... nevermind) once their binded, power both TX and RX off, pull the bind connector / jumper off, then your good to go.


Note: For safety, disconnect both main motor plugs from the -in-1 control unit (as shown on page 1 )
before proceeding. Once the binding process is complete and the flight battery is unplugged from the
-in-1 unit, reconnect the main motor plugs to -in-1 unit (as noted on page 19).

oops! your right i forgot the cx2 has a totally different frequency system!

Read the book? What kind of pervert are you?

We're MEN.
We don't need no stinking BOOK!
We got . . . ummm . . . Brains!.
Yeah, we got brains and they're real big and smart and we don't need instructions and we don't need directions.

So if ya wanna know something, ask yer buddy, but that instruction book should NEVER be removed from the heli box.

That's why men use forums and women have book clubs.

Hey,

that's thru only thing I read are rc magazins ! I was on vacation when the error occured had everything with me fast repair kit (cya glue) but of course I didn't have the manuel with me and didn't find any on line! So I thought asking you people is the fastest way. Wich really is as I'm already flying again
Thx for the help keep up the good work.

On vacation with no book. So you came to the forum. I'm sort of embarrassed to admit this, but I'm not sure I would have thought of coming to the forum. ( and I like your "CYA" glue comment)

Glad you got the information you needed. Obviously I was just being a wise guy. Except for the asking directions part. Real men never ask directions. We use a GPS.

Get your manual and use the Bind Plug the 4 in one came with.Page 40 of the manual tells you how to do this.Send your ld one to efite to check out and maybe send you a new one. Ron

BLADE CX2
-My lipo got too low and had a charge error.
-Replaced battery with new battery and 4 in 1 then blinked alternating red & green light.
-Followed bind procedures. 4 in 1 still blinks red & green.
-Replaced 4 in 1 with new unit, followed bind procedure and light still blinks red & green.

Blinks red 3 times then alternates red & green.

no blinking orange light to be found
*TX batteries are at 5.8 chage level.
*Throttle & throttle trim are in their lowest position.

Anyone kind enough to offer any help, please let me know.
The unit has been flown in doors 4 times, 4 charges, 0 crashes. 0 power problems in flight.
then this happened

Anyone have a suggestion?

sounds like your binding didn't work. Try that again and see if it makes any difference. Does the orange light on the reciver side (opposite the Red/Green side} light up and stay on?

Looking at the manual [link=http://www.e-fliterc.com/Products/Support.aspx?ProdID=EFLH1250]Found Here[/link]

To bind your RX to your TX:

Sorry about the way the instrructions got all garbled there......... I copy pasted from a PDF file.......

Of all the things I ever lost....................................... I miss my mind the most!

With a new 4 in 1 and battery, (throttles all way down) the onl lights that go on is the flashing red & green.
No orange light at all on the other side of the 4 in 1.

Basically I'm stumped in the first step.
Bind plug is in, motor plugs are pulled out. (I tried plugging in the bind plug both ways too, facing up, facing down).
I plug in battery to get orange light, but it flashes red three times and then continues to alternate red & green.

I know it's not my TX controller because I can't even get past the 1st step here, which doesn't involve the TX.
Only other electronics are the servos...

looks like its the TX

It's not the TX....yet.
I haven't even got to the stage where I need to power the TX up in the bind process.

I'm in the 1st step of the bind process. With the bind plug in the top battery slot. No orange light comes on when I plug the "new" battery into the "new" 4 in 1.
Just flashes red & green on the opposite side.

I've waited for it to turn orange... even up to 10 minutes...no orange light.

Ok , I re-created your situation, and here is what I found.

I got my old stock tx and put batteries in it. (My CX2 was bound to my DX7).
I plugged in the battery pack first....Left the bind plug out and all it did was blink red and green.
So I unplugged the battery and put the bind plug in and the orange
light started flashing.
So this must mean that either that lilttle black wire is broken on the
bind plug, or it is not making a good connection somewhere (either in the bind plug assembly or
the 4 n 1 controler.

I would say try a new bind plug. You should have had one with your original package deal and
the 4-1 comes with one.

Balance,

Thanks so much for going to that effort.
My CX2 just isn't having it though.

I have 3 bind plugs (1 for mine, 1 for my brother's, and 1 from my new 4 in 1)
All 3 failed to turn the 4 in 1's orange light on. I even went so far as to get a peice of wire (after trying all three and securing a direct connection between the 1st & 3rd pegs in the battery slot. No luck. Tried it on both of my 4 in 1 units too.

Other signs:
When I turn my brother's CX2 on, his servos auto adjust w/out the TX on. Whereas mine don't ofcourse. Only electronic activity is red & green lights.
I noticed that when I plug my servos into my brother's CX2 and power his unit on, the servos' don't auto adjust. When I plugged my servos' into his heli it turned orange the first time, then powering up again, HIS heli started to flash red & green like mine! Uh oh!
I quickly put everything back to normal on his and powered back up his heli w/ his TX and after blinking red & green for a little it turned orange again and all was working fine w/ his. I was afraid I screwed up his heli by connecting it with the servos from my CURSED CX2!!!

My unit is CURSED electronically.
Anyone have any energy to offer another solution?
I won't blame you if you don't!

Then one or more of your servos must have been damaged in that crash and it is putting strain
on the 4 in 1 controler. If your brothers came back to normal, then I think you probably didn't
damage his.

I would say try to bind yours with EVERYTHING else unplugged.....see if it will bind.
If it does then you need to get either 1 or 2 more servos.

Thanks Balance. I took it in for service to the best heli repair guy in town.

Servo's are good.
BOTH 4 in 1's are good.
Bind Plug is good.
TX is good.


***NEW battery is defective.
Old battery had charge error lights on.
New battery showed full charge (solid red). But no power was tranferring to the 4 in 1 (so thats why blinking red & green) needed more power.
1st time he's ever seen a defective Lipo E-Flite battery.

Its running now with a new battery.

Thanks everyone

What did he use to test a battery to see if its good.It must be a special charger tester.Ron

You say thank you now, but wait until the bills start coming in!! You don't think this brain trust runs on "Thank You's" do you?

LOL


Isn't this about the greatest group of folks you've found? These guys will do anything to get a fellow flier an answer.
That's pretty cool.

Glad you got it going! [8D]


And LOL soloboss [sm=lol.gif]

I would suggest to anyone that is going to fly the CX2 (or any electric heli) often to get a good
charger and get away from them factory ones.

My balanced charger shows the voltage of each cell, so I can see how low I let my batteries get
(yep even I overwork my battery sometimes even though I try not to). And I can see if the voltage of each
cell is staying close to each other. You can't tell much from a couple of lights on a charger.

Worth the money.

I have an Ice Duratrax Lipo charger for my car.
I need to get the right 7.2 volt balancer connector, but will that work?

I don't know , you might ask your local hobby shop guy about that one. I tried to look up the
model you had, didn't know exactly which it was. But it looked to me like they could do 1-4 cell lipo's
but it didn't look like it had a balancer. I don't know anything about it and don't know if they
sell a balancer for it or not.
Or maybe someone else here knows.
