Stryfe rewire and upgrade motor issues

Hi guys,

I've just rewired my stryfe and added a couple of Hellcats. The circuit is all working and I've plugged in the LiPo and it's still all working. Except the flywheels are spinning backwards. I've double checked the motor polarity with the video by FDS on YouTube and mine matches, I've checked the wiring with the rewire video by FDS too and mine matches, I can't see what the issue could be.

Below are some pictures of the three connection points, please excuse the atrocious soldering.

You've wired your motors back to front. Don't worry, it happens to the best of us.

The easiest thing to do would be to reverse the polarity on your XT-60, otherwise you'll have to mess about redoing the motor terminals.

I thought that would be the case, but my red dots appear to be correctly orientated which is what confused me (unless I'm simply not seeing it properly)

Unfortunately for me the xt-60 connections are my only good bit of soldering, and I even heat shrinked them.....lesson learned Smile

Thanks for the help!

It's always best to go back and do it properly anyway. Just think of it as practice.

I have had 2 motors with incorrect polarity dots.
Swap the motor link wires, everything else can stay the same. Shrink wrap the microswitch connections though.

XT-60 switch around did the trick!

Although in my giddy excitement I forgot to add the heat shrink to the wires, I'll try and sort that tomorrow when I tackle adding the voltmeter Smile

I tend to switch the polarity at the motor block because people panic when the Lipo polarity doesn't match at the connector!

I would have preferred to have done that myself, but my soldering skills, lack of spare wire if things go wrong and a time limit (trying to get it finished for GuN) meant that swopping the connector round was the way to go.

Based on the image it looks like the polarity markers on the motors are correct and it's just been wired up backwards (again, happens to everyone at some point). When wired up with the positive from the battery connected to the side of the motor with the red dot, the motor should spin clockwise when looking at it from the end bell (anti-clockwise when looking at it from shaft-side).

I do this all the time. So what I do now is I solder onto the motors then check with a smaller battery that they are running the right way. Once I am satisfied I solder the rest. Like UKNerfWar said, quick fit is to swap to xt60 over.

I always test fit it first and then again as I go through the soldering. Know your enemy, especially when your enemy is you.

Today i did the same thing. So i swapped at the motor to then find i had my battery connector round the wrong way so fixed that, re-opened the blaster to put the motors back the right way!

Just to finish the story, this is the above blaster finished.
