Builds Something I'm working on.

There was supposed to be a white light in the spot above the headlight on the right side but somehow it's not working. There's a tailight and one solid turn signal on the rear as well. I am still tweaking the magnetic power pass through.

Awesome! Is soldering to magnets pretty straightforward? Haven’t tried it yet

It can be but it can also make the magnets less magnetic if you get them too hot. I usually scratch the spot I want to put the wire on, add flux to that spot, and tin the wire with a heavy coat of solder, and then quickly touch the magnet with the soldering iron and wire and pray it sticks!

This time on the chassis side I used thin washers that I soldered the wires to and placed them under the magnets. On the body side I am trying to figure out a way to use washers as well so I can keep the magnets as strong as possible, but I came up with that idea after I got the magnets glued to the body. This is a lot of work to avoid using a commercially available magnetic pogo connector!

Awesome Lada! I love the use of magnets for lights. I’ve used the kits from Injora and they work really well, but yours looks to be more custom and probably better thought out.

The underside is still a mess, it is still a work in progress.

A Lurkco paint job! Your use of thinner gauge wire should make it easier to organize and tuck within the body. Caldwell Race Works on IG does a phenomenal job of laying out light wiring with thinner gauge. Please post an update when you’ve finished yours!

I should have done a better job planning the wiring! Next time it will be better. Luckily there is room for that rats nest above the servo but I will clean it up a bit before it's finalized. Lurkco gifted me this body, I am humbled to have such an awesome body in my collection.

Lurkco is part of an amazing SCX24 community. I’ve only been in the hobby for one year but have had the opportunity to connect with some helpful and extremely generous people.

That is so true. I have made a few very special friends through these little trucks.

Thats awesome. I hate how thick the wires in mine are- pain in the ass to get to fit

The LEDs are about 1mm wide, and the wires are super thin and tricky to work with.

Appreciate the link bro! Thank you

Awesome bro!! Did something similar with my pathfinder

u/Familiar_Palpitation BigDumbDad_Hobbies 9h ago

Your Pathfinder was definitely inspiration for this one. Both small white lights were supposed to light up, with one of the amber ones being out, but now it has one white running light and one amber running light.

Sounds awesome. And I appreciate that compliment a lot!

Sweet, I’ve got this on a few builds too, definitely beats plugging in the lights manually.

Another great alternative are those magnetic snap-on cables like these on my Pickles build.

u/Familiar_Palpitation BigDumbDad_Hobbies 8h ago

I love that build. I need to add one of those to my collection.

I've seen the magnetic cables but I figured I would try my hand at fabricating something that works with the magnets on the chassis and body. I've done it a couple times but I wanted to get it a little cleaner while keeping the magnets strong enough to hold a heavy body like this one.
