Wiring help

[cammo47]

Hi all,

Its Andy here form Cambridge.


I have a question that seems so simple there isnt an answer to it.

I purchased a Twister 3d expert with gyro, esc and battery.

I was supplied with all connecters to compleate the job.

But I do not have, find or cant work out how to wire ecu to motor and Lipo???

I am by no means new to helis as i have been flying my Sceadu evo 50
for since it was released.

please help as no instruction where given and the model shop i got it from has closed.

a diagram would be great

any help would be Mucho appreciated.

can you describe the ECU? Is it a brushless motor?

[cammo47]

Its the brushless version.

the Ecu is not the twister version, as iwas informed JP had problems with them? so the ecu is one jp reccomended to the suppliers.

not too shure of manuf but definatly a brushless version.

the problem being all the wires in and are yellow so no idea of polariy at all.

the only info it came with is error codes and tech info not wiring as they stated all equipment was different.

any ideas?

Thanks

[jimbob]

well... the 3 output wires just go on to the motor. If it spins the wrong way, just reverse one pair of wires.

You mean to say that ALL the wires are yellow? Thats very strange!
Can you see the board at all? If you can see the polarity of the electrolytic capacitors, then they will almost certainly be soldered in mind of the polarity of the input - ie, -ve to -ve and/or +ve to +ve.

Thats the best i can off without seeing it.

Sorry i thaught all the wires where yellow.

I see what you mean now.

But it dosent answer my problem,

My receiver manual states that one of the slots next to the servo ports is for power in.

Now this has causeD many a disputes between me and my father as we are unsure weathe the ECU supplies the RX with power or do we use the power input slot??

I recon the former as the latter wont fit.

I cant do soldering so persuading him to wire it (the wrong way) is inpossible.

Am i right? please say i am as iv had the heli for about 4 months just sitting there looking eager.

Now I've seen the thing, I get it
I was confused by the ECU term... I know there's a lot of jargon and acronyms everywhere - but this is an ESC - Electronic Speed Controller.

The ESC powers the heli as you thought - you plug it into the throttle channel of the receiver, which gives the receiver power at the same time.

As jimbob mentioned - wire up the motor connectors anyway you like - if it spins the wrong way, simply swap any two of the three wires over and it should go the other way instead.

I use 3.5mm gold bullet connectors between my motors and ESCs.
I hope that helps.

In case it helps, you have:

Battery -> ESC -> Receiver and Motor

ok - well the normal would be as follows:

The Drive battery joins to the red and black wires as you would imagine.

The servo connection of the ESC plugs into channel 3 of the receiver (futaba system).
The ESC now powers the receiver through the channel 3 connection and gets its control from the receiver.
This is dependant on the ESC having what is called a BEC or battery eliminator circuit which is designed to use the drive battery to power the receiver.

Some ESCs allow you to use a separate battery for the receiver as well such as the Kontronic Jazz.
The motor connects as described before.

As far as the receiver is concerned, all the red and black connections of each servo output are common for a normal receiver, so you can actually plug you battery into any of the outputs, not just the one marked 'B'... Hence being able to supply it using the throttle channel (3 on futaba) output.

Hope this helps. No soldering required!

Ah wicked guys, thanks for helpin out.

I was 99.9 percent certain i was right but dad reads gospel off manuals so.

Ill be flying it by tomorow!!

AAh I cant bloody wait.

Ive got a 1/2 achre grain barn to fly it in. I fly the sceadu in there whitch is fun.

Cheers once again people.

Andy

[jimbob]

Youre welcome and good luck!

Ive got a 1/2 achre grain barn to fly it in

DAMN!!!
Thats not near Shrewsbury by any chance is it
Heh heh
Cheers,
Rob

hope theres not grain in it...lol
