Bob,
I have a very important question...
I decided to shorten the wires on the TT Ripper motor for my E550 before I put connectors on. I had NO IDEA the wire they use would NOT melt solder. After my 40W iron wouldn't cut it I took out my 150/230 watt gun and tried it. Still wouldn't work. After scraping the wire strands with a razor blade to see if there was some kind of coating on them I was able to get a "small" amount of solder to adhere.
I'm using the standard bullet connectors that TT supplied with the motor. Trying to remedy the situation, I made sure there was plenty of solder in the connector and I heated both as hot as they'd get with the gun and attached them. Then, I put a LONG piece of shrink tube over the connector for added insurance.
My problem is I'm a little nervous that the connector(s) might overheat and separate in flight. Is this something I should worry about? If so I don't know what I should do short of getting another motor or finding someone with an industial power soldering gun.
I had NO PROBLEM with the heavy guage wire on the Castle HV85 so it's just the TT motor leads I'm concerned about.
What do you think?
I wish I had known how hard the motor wires were to solder. I would have just left them alone since they were pre-tinned.

Im pretty new to Heli's but I've been doing electronics for 12 years. I would use some solvent to remove the Enamel coating on the exposed part of the wire you want to solder and give it another try.I would only do this as a last resort! You need to be very careful since some of the solvent will wick up the into the wire and start to soften and degrade the wire insulation and the enamel coating that you want to leave alone . Make sure you try and get all the solvent off before soldering.
