Just a thought, what voltage is the battery you plugged into the esc. Apologies if you've already mentioned that.

[Neil]

jusdt a 4 pack of 1.2mhp pencel batteries.

[Neil]

i have checked the wires to the motors as oposed to the batteries and those are correct too as the middle black and red are going to the two  batteries, and the outer ones to the motors

[Neil]

well!!!, i think i have found one problem in why these two sets wouldn't  work, not only on the rig that i had put together but also when i brought out 3 servos to test them and the systems on.

I was given one set a couple of years ago and the other set I bought at a bring and buy a few weeks ago.
TOOK THEM FOR GRANTED, as the kind people guarrenteed that they worked.

However, tonight they didn't after i had charged them both up............
But I didn't check the frequencies of the tx's and rx's............there in lay the problem.......2 x tx with the same frequency, and one Tx and one Rx matching but NOT IN THE RIGHT PLACES in the same transmiter and matching receiver, and until today had never touched them. so i had one set with a tx and none matching rx in one set and the other set with 2 tx in the transmitter AND RECEIVER......A TOTAL MISH MASH.

So now have one set working and one set of 2 tx cristals..........but i have some crystals somewher so will matche up to make two more sets...............and now i have a working tx/rx that i have tested with servos, hopefully i can have a good night sleep and conect up to the set i built, and if it is all go and working tomorrow will put in to the boat, and finally name her.

bit superstiscious but i wont name a boat until everything else is sorted.....keep your fingers crossed folks.

[chas]

We've all made that mistake with crystals. Re the battery, 4 x rechargeable batteries are only 4.8 volts and I think the esc specifies 7.2 volts. I certainly wouldn't expect it to work on less than 6 volts.

hi there Neil


Let us hope we have it sorted this time.


Last but not least - if you are going to connect two of these speed controllers - into the same receiver - you will need to remove one positive red wire from one speed controller, as these both have BECs - and if you don't you will have all types of problems.


Best of luck


John

[Neil]

well, I have to admit absolute failure, sadly

After checking all the fuses, connections etc, I connected the leads up to the motors, batteries, and then connected them to the same plugs as the servos I used for testing, including one for the rudder servo and tried......no fuses blown, rudder servo worked as should................and sod all from the motors...............even the lights in the esc's didn't come on. So I plugged in a 4.8v pack of pencel batteries, no fuses blown, red lights on esc's lighting up, rudder servo still worked, but no joy with the motors.........

What have I done wrong.......is there anyone within a 50 mile radius to Blackpool that I could bring this set to, to sort out for me please. cheers.

[Neil]

SORRY JOHN, connected them all before i saw your note about removing one red lead.........will try again now.

[Neil]

just tried removing the red lead from one esc/..........and not even the rudder servo worked after that move..............
HELP!!!.............I NEED A ROCKET SCIENTIST LOL. 

[chas]

Hi Neil, I think you're tying yourself in a knot here, please try this.
Disconnect everything.
 Plug one esc into the receiver. The one with the red wife still in place Check Plugs are the correct way round
Plug one servo to the receiver.
Connect one motor to the esc
Switch on the correct transmitter, all sticks in the centre position
Now plug a 7.2 volt battery into the esc, NOT a 4.8 volt pack.
 That should work, if it does, report back and you can move on to the final bit.I

[Neil]

right, chas. will do that. i'll do it later this afternoon as am making some planters at the mo for my daughters new house gareden..........needed a break.........it was/is driving me loco.

[chas]

Great, good luck. Take a picture of it set up if you can.

[John W E]

Hi there Neil


Just to add a could of things to what Chas has already mentioned.


First of all, it would be prudent to prove that the actual transmitter & receiver are working 100% by one servo plugged into the receiver, plus your 4.8 volt power pack.   This will prove that the receiver is working okay.


Next, have you got a main power pack of more than 7.4 volt so we know that it is fully charged?


Then, proceed as Chas has suggested    .


I know it is heart breaking but, we will get there in the end.


John

[Neil]

here we go, Chas,  the two diferent sets of wiring with the esc's have been tested individually on both motor sercuits and nothing at all. no fuses blown on either wiring set

[Neil]

hi john.........just tested on a servo with just the plug in 4 different positions with a 4.8v battery and all possitions work, but when i plug it in with the esc's also plugged in but without the 4.8 v pack, relying on the esc using BEC power from the main 7.2 v pack and they are fully charged, the servo won't work.

[Neil]

Hi there Neil

I know it is heart breaking but, we will get there in the end.


John

Not heartbreaking John.......just very annoying that i can build a boat , just cant get it to work lol.........ITt's why i havent sailed a boat in 4 years cant be bothered with the electrics.so many nice models I have never sailed........thats sad. but determined to get this one working.

[John W E]

hi there Neil


I had a good study of your pics and blew one or two of them up or should I say enlarged them    so I could have a good look at the solder connections and also the way you have wired it up.   I think you may have your wires mixed up, the wires you have from your main battery should be the wires to your motor.


The other pair of wires that you had on your motor originally should be to the battery.


Now, I am going to try and obtain a very clear picture of the layout of the wires I have - you could then compare with what you have.  Hopefully that will be helpful.


John

[Neil]

thanks John......all help much appreciated. 

[Neil]

yep,       according to that photo, i have got the two sets transposed.

however now looking at what Bob said, and whaT Roy said I now see that they contradicted each other, but I never noticed it.
so as the set up i have done doesn't work at all except on a servo, I will now slowly swap them around one at a time.........only thing wasted due to my stupidity is some tape, and time..........but it has been a good learning curve and will come in for when i wire up my little Atlantic 21 ribs.
more luck needed please lol.

[Neil]

right guys...............first one done with my usual decent soldering with soft dolder...........much better with silver soldering with a brazing torch, but can do softly when needed lol

the outer black and red now transposed to the batteries, and using Deans conectors cannot confuse the two sets, where as the inner black and red wires are to the motors.

[Neil]

where does 2 hours go..........at lerast all joints have been given their utmost attention....

I just hope it all works this time.

[Neil]

This is now becoming a chore..............never had any trouble before with electronize escs and my set ups

and yet...........followed all instructions including taking the red lead out of one esc conectin, and 2 hours later..........all i get is one flashing light from the esc WITH  the red lead still conected, and sod all else..........even the rudder servo wont work!
so then i connect the little 4.8v seperate battery pack i get a constant light on the esc that was not lighting up. and the esc that was flashing constantly now goes off until i move the right hand joy stick then it flashes in the horizontal movement of the stick.
but when i turn the tx off i still get a constant light on one esc and the esc with the red lead removed, a flashing light......and if i pull out the 4.8v pack the constant light on one esc goes out and the one withn the red lead removed the red light continues to flash merily away like christmas tree lights.


make of that what you will.................i am totally out of my deapth.

[chas]

Hi again niel, if you had the power going into the motor connections, I'm pretty sure you'll have blown the esc, no remedy I'm afraid. Perhaps it's time to mend them with new ones.

[John W E]

hi there Neil


Sadly, I tend to agree with what has been said - accidentally you may have fried these speed controllers.    Before condemning them to the bin though - there are a couple of things to try just to ensure that they are 'fried'.


Have you tested the motors without the speed controllers? straight off a battery.  and do they work?


Do you still have the Mtroniks speed controller which came with the model?   If so, connect one motor up to the speed controller without fuses - making sure you have the leads the right way.   If you are unsure - the link I previously put on to the Mtroniks website will show you which leads are what.


Then, plug this speed controller into your receiver and does it work?


Then, once happy knowing that the motors and everything else works - you may be able to come back to the speed controller which blinks all the time.    If it is blinking, have you tried this speed controller coupled up to a different motor/a smaller motor.? 


Normally a solid red light indicates no signal from the RX.


The only thing I would really say - is - I am not a personal fan of these type of fuses being put in between the speed controller and motor because I have come across one or two in the past of this type which have a built in resistance.

hi Neil


i know you are confused.com with electrics why dont you save yourself a load of greif and SIMPLY pop down here to sunny North Wales and ill strip everything down and sort it out for you whilst you wait and ill SHOW you how to do it properly
