Advice resolding ESC wires

[AdrianH78]

Hi All,

I am changing from a SV2 to a KF, but due to motor and battery relative positions, they have entirely different wiring requirements.

Unfortunately this means I need to shorten the motor wires and add two new long Battery wires.

The ESC in question is a Orion R10.1, but being honest I am very reluctant to put a soldering iron to it as it is a nice expensive thing..

How tricky is it to change the wires? Don't fancy simply extending the wires as this always feels like a bit of a 'bodge'

Cheers

Adrian

With the right iron and tip they're not bad at all. I've done a good few for similar reasons.
Need a powerful hot iron an a tip that isn't too big, chisel/wedge type should be OK.
If you're unsure/apprehensive maybe somebody at your club might be able to do it for you?

Good advice from charlesk there. I have done loads, good hot decent size tip, well tinned and extra solder on the tip should reflow the solder on the ESC easily to allow you to pull the wire straight off.

Do not cut the wire short before desoldering as it is good to have a decent bit to hold onto and pull away from the joint.

Once the wire is off, I would clean out the ESC solder pots with a desoldering sucker or braid so that you resolder the wires back with fresh solder with new flux in it.

Then make sure the new wire is properly tinned all the way through, run the iron all around the wire so it is nice and shiny, re tin the ESC and then solder the wire back in.

Hi,
I have re-soldered many Orion speedo's but have found that a hot/ powerful soldering iron is a must, extra solder, but you must not get the speedo too hot, many of the failures with these speedo's is after soldering, do one wire, leave it for a while to cool, then do another wire,

Use some blue-tak to stop it moving about when soldering.

I even servo taped it to the bench once.

Adrian, do you race at Silverstone? if so I'm sure someone at the club will help you.

Ahh no worries personally when i do them i have a £25 iron ftom maplins thats adjustable power, with flat-ish tip once the wire is removed i then use a solder sucker to remove any excess solder on the speedo. Try and use a led based solder if possible as you will find it will flow alot better and you will get a much more pleasing to look at shiney soldered joint if you find you struggle to remove the wire from the speedo shorten the wire to a point you can still get hold with a small pair of pliers, by shortening it, it reduces the heat required or length of time you need to keep the iron on the joint to remove the wire this is because the wire doesnt act as a heat sink.
