Brushless problem

Not a robot question, but closely related enough I think. Got the setup seen in the picture. When I power up the motor beeps until I switch on the Tx, after which I cant get anything to happen.

Any idea what the problem is?

Thanks a lot,

James.

Throttle needs to be down. If it keeps beeping it means the throttle is not at its lowest point. You may need to trim it to minimum. It should then beep a different tune and when it is finished you should be ready to go. See if this helps.

I would have thought it's what Harry said, but if not... does the speedo have a BEC? If you power the ESC up but there's no power to the receiver it will just beep like you said. Try plugging a smaller battery in to power the receiver.

Hmmm, funny...

The receiver is getting power- the power light comes on (and it is bound to the Tx as the light goes off when the Tx turns off)

Video of the problem?

will do

Looks like your signal cable is upside down in the rx.

I was about to say the same thing, signal wire is in the wrong way

Flipping the wire going into the receiver round seems to just cut all power to the rx (this is why i had it they way I did).
The power light goes off in the Rx and the motor makes the same noises that it does if the rx is completely disconnected.

I think you wired the motor wrongly. When you add power it turns a little before beeping.
Have you tried disconnecting the motor and just test it with a servo or anything else you know works.

So wire a servo where the motor is now? Should I try switching the wires round on the motor?

Is there any way to tell which wire should go where?

Your thing is plugged into the RX the wrong way round. It seems to be on even before it has bound. Try it and see.

And when you turn the cable around hold the trainer switch while powering the TX.
Perhaps you never really bound your system in the first place.

Back to your servo question, just put the servo cable directly into your receiver in the same slot your esc is in now.
If I saw it correctly it was connected to the throttle channel which is the lever that you can set to a specific setting without it selfcentering.

(I do apolagize if I sound like I'm talking to a child, I just want to make it as basic as possible for I do not know how much experience you have with RC equipment.)

Harry: I tried flipping it round and there was no power to the rx at all :/

That's really odd. Is it all bound correctly yeah?

Yes, I've rebound it a few times to be sure, but when I switch the Tx on and off the light on the receiver goes on and off accordingly. I'm guessing that means it's bound?

Ahh- when I plug a servo in it just shudders and grinds when the Tx is switched on, but doesnt respond to the Tx...

Humour me. Stick the bind plug in, and then power it up the opposite way to how you are doing it. See if it goes into bind mode.

The Rx doesnt go into bind mode like this (just tried it)

Is your transmitter Mode 1 or Mode 2? Your ratchet stick is on the right but if the TX is still set for Mode 2, the left hand stick up/down is your throttle channel, into which your brushless ESC is plugged. Try powering up the setup with the left hand stick in the fully down position, or change the ESC plug on the RX to the ELEV position, and power up with the right-hand stick fully down.

I thought you might have been onto something here- but no joy :(

Is there a way to change the modes?

I don't think the problem is with arming the ESC, otherwise the servo would work. So it shouldn't matter what mode it is.

I think the problem is with the receiver. I'm guessing maybe keeping the plug in upside down for an extended period of time may have caused it to fail? Do you have another receiver you can test it with?

I have 2 of the same receiver, and they do exactly the same thing. Is that likely? The lights still come on on the receiver...

If the problem has been caused by plugging them in upside down, and you've plugged them both in upside down, then yes they might both be broke now. Lights coming on doesn't mean a receiver is working. If the servo worked I would say it's a problem with the brushless setup. But as nothing you plug into the receiver works, I'd say it's a problem with the receiver.

Ok, thanks. For my sake- how do you know which way up to insert the plugs? There is no labelling on the Rx at all!

White (signal) faces the front of the rx, I made the same mistake with my first rx and it totalled it and the esc it was connected to

Yep, the signal cable is always the lightest colour cable (typically white or yellow) of the three and it goes at the "top" of the rx. Might be worth writing a +/- on the receiver's body as a mind jog. Naturally, then, the black cable (negative) is always on the bottom side of the rx.

Just a thought, You use an orange rx? From memory on the side they have an S over where the signal cable should go, at least mine did

It lives! Not sure what I did, tried rebinding it (for the nth time) and this time something was different. Thanks for all your help guys :)

Looks like you were being a bit quick on the tx for it... just sounded like it was waiting for a command... for future referance hold the tx stick on the channel your using (throttle) totally to the top of its travel, turn the tx on...wait for the motor to make different beep sound...then bring the stick fully down and wait for yet another beeping sound... this arms the motor and teaches the esc the channel limits.

And also you had the motor wired fine... the only thing you will achieve by swapping the motor wires around is reversing its direction of rotation.

Cheers! :)
