HELP! can't get solder to adhere!!
I have an E-Flite H500 and a Scorpion motor that I wanted to shorten the leads on and no matter what solder I use I cannot get it to flow on the wires. I stripped the insulator back from the original leads and there is plenty of tinning and solder flow. Not even my LHS can get it to solder. What if any advise do you have?

Scrape the very thin clear plastic coating off the wires with a razor blade. You can also soak the wire ends in paint stripper or use a Dremel and wire brush. The solder doesn't stick because the wires are covered with some high-temp plastic.Avant RC

What scorpion motor. Could you show a picture of the leads. Most of the scorpion motors I have seen have high multistrand copper wire which should solder fairly easy with rosin core solder. It may be the case that the wires your are dealing with are the actual windings extended outside the motor case. If so the area of the wire you wish to solder has to be mechanically cleaned of the protective coating.

Sorry about the multistrand I was thinking of a different motor. Scorpion has the winding leads out to the bullets.

Get the wires clean and use a good electronics grade flux.

I spent about an hour stripping the strands with 220 grit wet/dry paper then cleaned them with contact cleaner. they looked nice and brite but still no go. why would the wire inside the insulator be any different than the ones in the windings? looks the same when you strip the insulation off. I have never had any trouble soldering bullets before.

From their website it looks like they are the solid wire motor leads. I have heard many have had difficulty soldering thes if the cut them back. I would shoot an email to scorpion or Lucien Miller at innov8tivedesigns.com. May require a specific flux.
What solders/flux's have you tried?

The video does not give a solution but gives the reason why at 4:30 in.
I think if you use a thin paint stripper or lacquer thinner and then rinse leads with acetone you may get it to take. You need to remove all traces of the lacquer coating on the wires.

I have used the standard fare of solders and fluxes, hobby shop stuff, radio shack and some that I had at home. I will contact scorpion tomorrow. when you say solid wire motor leads are you referring to one larger strand of wire?

The motor wires are actually the motor winding wire that are twisted together. You need to untwist all three motor leads and scrape the enameling off each one of the wires, use a blade not sandpaper. once all the enameling is off re-twist the wires, add your heat shrink tubes to insulate all three wires from the motor case and each other, leave enough of the wire ends exposed to solder you bullet connectors on.

do a search on it from the home page, make sure you wear a respirator the fumes are nasty. basically you put an asprin on something that won't burn, I put mine on a small piece of aluminum, seperate all the strands, put some solder on the iron and then heat the strands while they are on top of the asprin rubing back and forth, up and down the strands until they look tinned then turn the wire over and repeat. scrub the strands real good with a fine wire brush and hot water then rubbing alcohol, twist back together and you are ready to solder.

Glad you got them tinned Daddyo
I needed to solder some lacquer insulated wire and a Google search brought me here. I figured I had little to lose by trying the aspirin tablet idea, but I modified it on a whim.

I have a small container of soldering paste flux. I applied a small amount of paste flux to the aspirin tablet, and to the wire, then heated the flux up on the tablet.

Whoooo boy!!! I was doing this in the garage with the door open and the breeze pushed some of the fumes my way. I'm allergic to aspirin and didn't think of how dangerous it could have been.

Lucky for me, I stopped coughing after a few minutes and tried again. With solder on the tip of the iron and flux on the aspirin and fumes wafting all over the place, I got the wire tinned beautifully!

This was the best result I've ever had with lacquer insulated wire and I recommend it, but only if you've got a small fan blowing the fumes away from your face.
