Hi,
I have purchaced a esc from the BBB store, but it doesnt apear to be working. I have wired up everything like the diagram on the page shows. The drive motors work just not the spinner. I have tryed with a new esc aswell but it still didnt work. I was told by someone that i should scratch the gold of the pads. But it still didnt work 
Any help would be appreciated. Im probably just missing something.
Thanks
Some photos of your setup would be helpful. It’s quite hard to work out what’s wrong just from a description
And you shouldn’t scratch the gold off the pads. That’s the conductive bit, it won’t do anything without it
That soldering for sure needs some work I’m afraid. Slightly too much solder and perhaps not quite enough heat.
Are you getting a song or beep tone from the motor when it is turned on? If not the ESC or motor connections are dud.
If you are getting the tone but no movement I think it is not calibrating a zero throttle and so won’t start that way. Make sure your throttle is at zero (and make sure it’s hooked up to the right channel, 3 not 4) lower the trim on the throttle as low as it will go and it should arm.
I am not getting any sound from the esc or motor. Though all connections seem sound. Il have another check. Is there a way i can see if the esc is powered?
Multimeter is the best way but if you have an LED or motor you can put on the ESC terminals that’s a decent ghetto indicator
BIG EDIT - rescanned the picture
Are you only running 1s? That’ll also do it. It’ll need a minimum of 2s to work.
What do you mean by only running ones?
The amount of cells in your battery, usually 1 cell batteries provides 3.7 v like yours, you need a 2 cell battery for the esc to be powered (this should have 7.4v).
1s, shortened version of saying one cell. Looks like you only have a single 3.7v lipo cell powering everything. That’s likely too low a voltage as the esc is designed for 2-4 cell (7.4v-14.8v) operation. Most ants run 2 or 3cell.
Oh, so i just need to get another 2 of thoes cells and wire them in series?
I would create (or buy) a single 2 cell pack. Remember the normal malenki nano is only rated for 2cell operation.
One of these would be an option:
Its a bit on the large side, but isn’t unreasonably heavy for an ant battery. It should also plug directly into your current connector. (Double check though, I’ve seen some wired backwards)
I would also suggest removing your weapon from the motor when you are testing it. The motors have a tendency to throw themselves around at the best of times, and the weapon bar will make that an unpleasant experience
Ok, thanks for your help guys. Would you have a charger recommendation for that battery?
BBB have charger recs down the bottom of the page here
As others have noted, a single cell isn’t going to provide enough voltage for the spinner.
However, I think that pack also won’t provide enough current.
Looking carefully at your battery, it looks like it has a protection circuit board. This is normal for single cell lipo packs used in devices such as smart phones, speakers etc. It will contain a current-limiting circuit which will probably limit the current to be too low to spin up your weapon, even though the drive may work ok. I suggest using a 2S RC lipo pack. These don’t have a protection circuit so you need to be more careful, but can get a lot more power out.
