Have I fried another receiver?

[wolfdogstinkus]

Took the mad bull to the park today with my 4year old boy.

The black wire had come loose on the battery the other day and I soldered it back on, badly.

Car stopped dead in park and just bleeped, it has the TEU-101BK, silver can and 5000mah turnigy ni-mh that was a pain to solder, been trying all day to get that soldered again and it just wont stick to the battery wire.

Anyway, will need further investigation but I think I fried another receiver, of course the 101 doesn't have BEC, so I guess I have fried it.

But it has worked fine for a good few packs now. so unsure.

Its the acoms 2.4ghz stick radio

Has the receiver got a built in BEC??

What is the input voltage range for the receiver??

The Tamiya TEU-101BK ESC does NOT have a built ion BEC, so it will supply full battery voltage to the receiver.. Most receivers are designed to operate off 6Volts, so if you have one of those receivers and want to use it with a TEU-101BK ESC, then you will need to use an external BEC between the red plug on the ESC and the receiver..

As for soldering the battery wire... What sort of soldering iron do you have, and how long are you waiting for it to heat up before starting to try and solder with it..?

Thanks for the reply, Backlash, I think the solder wire is the problem, it melts ok, but just runs off the battery wire, wont stick at all, might have to try some different wire.

Pretty sure the acoms receiver doesn't have BEC and should operate at 6v, I blew the last one with a 3slipo.

Time to invest in crimp connecters and some new radio/receivers.

Just venting my frustration really.

Maybe its time you bought a BEC.. Either that or a better ESC..

You need to get the wire to melt the solder, not just the iron tip. Ideally you want to touch the iron to the wire until both are almost the same temperature, then either feed the solder

between them or melt it on the wire itself. If the iron tip is too small the wire will draw heat away from the iron and the whole length of wire will get warm enough to melt the insulation,

but not hot enough to melt the solder.

If it still wont take then either the wire is dirty or corroded. If it's dirty, use some baker's flux, if it's corroded some strands will appear black if you look closely. In the latter case cut away

the wire until you either get to a clean bit, or need to replace it as it's now too short.
