I'm not sure but now I'm kinda worried as I just cut mine down this week haven't had a chance to try it yet hope the b***h still works lol

Interesting.......I've never heard of that before.:weird:

Agree it seems odd. Which model, and some idea of where it says that?

What model is it? What exactly does the manual say?

The only reason I can imagine for requiring a minimum wire length is that the extra resistance will keep the surge current below the maximum that the MOSFETs or PC board will handle. That would be a pretty lame design.

This warning is in Castle manuals: "If you choose to direct solder or to shorten the motor wires, you may do so on the Castle Creations CM36 and Monster motors only. DO NOT CUT any part of the wire length from any other motor, regardless of brand or type."

Indeed, which LRP?

Mine definitely doesn't say that. Hell, they include super easy solder tabs which encourages it!

Could be two things, Sometimes the internal capacitors keep a charge on them and if you cut the wires at the same time you could short out the internal electronics causing a failure in the unit,
The other could be that the company just doubts peoples ability in soldering!

When I got a Castle system I found that odd and called them and was told to not worry about it. So I cut as needed and it works fine of course.

It's totally fine to modify the wires. But! There is a small chance you could damage something on the board or the case if you hold the iron onto the solder tabs too long. Many people sway the wires out on speed controls for different gauges and colors.

yeah i just wanted to shorten them up. they are a lil longer then i need them. trying to make the wiring clean as possible

Fatboy512 07-26-2014 03:42 PM

I cut the wires for the rx ????????????? Did I screw up

You cut the green one with red stripe or the red one with green stripe?:confused:

It's far more easier to just coil up the extra wire around a wrench to make a neater appearance. Once they're cut, too short for the next guy and risk the chance of bad soldering job and creating more problems. I personally don't cut or butcher any wires. If the receiver wire is needing more length, add an extension wire. I always thought that getting the most speed out of a car is more important than how the car under the body looks! Can't see that while under speed! jmo ;)

Just noticed you all are takin about the lrp mine was on a hobby wing sct pro but the ones I cut were red white and black they had gotta skinned up from the previous owner and he had black taped them so I figured while I had my truck tore down I would just cut them apart and solder them back and heat shrink them I'll have to look at it for sure on the color
