Still Conection Problems DX6I?

[Ronniebiggs]

I have had probs with my DX6I Losing conection with the heli. when I landed it would lose the conection when I changed battery's. But never mid flight etc. Then I did a rebuild with new motor and since then it loses conection mid flight causing me to nearly crash several times. I sent the TX and Rx back to the suppliers and they said they couldnt find a fault with it. But they replaced them for peace of mind. Still have ths same problem!!!
Im running 1 digital servo and a sonix motor. I have a castle creations phoneix 35A ESC and a seperate UBEC 5A max which im using.
Any suggestions. Fed up of problems. All I want is to fly but I have spent 90% of the time fixing or trying to figure out why its not working!!

The experts in the other thread may be able to help you LOL

I surely cant.. to me sounds like a blindspot problem

[Ber60]

C'mon guy's
We are the best in solving problems even if they sound so mysterious as Ronnie's problem I am sure there is a guy who has the same probl. and has a solution.
And you big D you are still my Guru act like one :mad: , are you getting aged to give up a good discussion like the 2.4Gh, like I said a "clash of titans" opinions opinions opinions, act like a titan you are worthy. Got my respect.:Bang

[Ronniebiggs]

Edited due to my error

[DierWolf]

didnt i say sounds like blindspot???

move reciever someplace else like at the bottom of the heli by the skids see if it solves the problem

H-Guy i could care less about and no thats not what ber60 was talking about :) or what i mean about "the other forum/thread"

[Ronniebiggs]

TBH you are one of the people I hope answers my thread as I know the advice is sound. Blindspots? yes you did say that. I dont know how that would work because the heli is only 5 feet away when it happens. The reciever is at the very front and the other bit at the very back. Thx

[Ronniebiggs]

Sry thought thats what you where on about. I get abit irrate about things like that. I appologise if that not what you meant. WIll edit the post.
:)

[DierWolf]

Have you switched back to the Belt stock motor to see if its not the the motor drawing too much? i know you say your bec is 5A (but like i said its 3A nominal 5A burse for very short time) so switching the motor would help see if its the current draw.

How is the wire between the 2 units? all ok ? no cracks etc? Whats your frame made of? give me more details. Pics etc

No i was talking about the big 2.4 debate going on in the other thread on this forum. :) Seems to be a guru in there that says nothing interferes with 2.4Ghz and all problems with it were solved. so figured he could help better... :)

[Ronniebiggs]

I appologise again:oops: I shouldnt have jumped the gun. Like I said I always appreciate your view. Along with the other lads when you all left I tried for a few weeks to find you all and followed you all here as you where all the best lads on Heliguy and without you all its not the same.

Here are the pics:thumbup: Various pics to see if you can spot anything.

Frame is carbon looking but I think its plastic. As you know its the HDX superframe. Motor you know. ESC castle creations phoenix 35A. Ubec 5A, 1 x futaba digital servo (Pic above) and the rest are SG90's

[Ronniebiggs]

The red tape mess in the first pic is a ferrite ring wrapped in tape on the ESC wire.
The disconected plug you can see is the black wire from the UBEC. The black insulation tape above the red is the ESC red wire taped so it cant touch anything.

My wires all seem fine. The solder joints appear ok as well.

Andy Where are the pics of your heli? I cant remember which thread, my memory aint what it used to be and it used to be rubbish:)

If your main receiver is near the front could it be too close to your Esc.

is it worth taking them off the heli and trying to duplicate the prob. If you cant you know its something to do with the instalation?

see if you can get it to happen with esc unplugged?

:hug:

[DierWolf]

No pics showing up dude.

Also if you have the dx6i or dx7 you should check the transmitter module for this factory problem

Correct
Note the antenna coax is routed under the main radio board.

Incorrect
The antenna coax is routed over the board in close proximity to power capacitors and IC’s compromising signal integrity. Please return to Spektrum for service. In the case of Futaba Hitec modules, a longer antenna wire will be needed.

"If your main receiver is near the front could it be too close to your Esc."

:hug:

NOOOOO, never that couldn be the problem 2.4 dont get interferance from anything :)

[Ronniebiggs]

Pics show ok for me? There on page 1? The factory took it back and replaced the TX and RX and still it hasnt made a difference

[Ronniebiggs]

My ESC is at the bottom at the back. RX at the very front above the battery at the top
Have you found the pics yet?

[DierWolf]

Well pics dont show here for us, including going directly to their link.

[Ronniebiggs]

does this one show?

[DierWolf]

They all show now.... tinypic probably had a problem at the time.


Well firstly.... 2.4Ghz cannot penetrate Carbon Fiber.
Second you have the main unit on its side on one side of the heli... this sounds and looks more and more like blind spotting...

I would redo the entire installion more neatly and better.

Take a look at this guys setup.

[Ian 777]

Yeah they are all showing now mate

All I know about 2.4 GHZ is that mine works:)

Is it possible that the coiled wires are causing induction and generating interferance.

Don't shoot me down oh mighty one if its a stupid suggestion:lol:

[DierWolf]

LOL hey i am not the one that said it.. the gurus in the other forum says none of this stuff can interfere with 2.4 :)

Just being sarcastic.... Yes you desperately need to tidy up everything on that heli.

[Ronniebiggs]

Ye I know. Its hard though I have nowhere to put things. I could remove the ferrite ring from the ESC and that would get rid of all that red mess. What do you think? Will rewire it and try again. Dont think it will make much difference. Maybe I will unearth something that I wouldnt if I didnt do it.:)

[Ian 777]

Seems very likely to be something in those bundled wires,

Very unlikely to be the radio thats at fault

Very unlikely to be local interferance

What's the ferrite ring do??

[Ian 777]

Again all the very best with it Andy, every one is wishing you success:thumbup:

[DierWolf]

Things you need to avoid.....

I am glad this thread came up maybe the guru's shooting my commends down will come and say other wise.

1. dont allow the antennas to touch the Carbon fiber during flight, Carbon fiber gets alot of static in the wash...

2. dont put it near the belt, here again the belt running thru the tailboom is like a vandergraf Generator (spelling sorry) creating TONS of static which is detrimental to 2.4Ghz

3. Get rid of all that wireing, wire it differently on the inside of the carbon fiber frame and neatly bundled together, find a good place where all servo's can reach the reciever and place the reciever as best you can with antenni sticking outwards out of each side of the frame and isolate them from touching the CF.

Same goes for the satalite antenna section.
