Build Thread Luke66's MKUltra 3D Printed RC Race Buggy Build.

[RetroThutmose]

Great looking build, how thick is the body?

 

[HPIguy]

First of all, the project looks killer! Second, did you put any type of protectant on the printed parts? Both PLA and PETG don't deal with heat or UV very well from what I've read.

 

[Littlemotor]

Cool project man! You absolutely killed it! What surface do you plan to run it on?

PETG does ok outside. PLA on the other hand turns into the wicked witch from Wizard of Oz if it even sees the sunlight

Thanks! I'd guess that it's about 3mm thick? I haven't measured.

Thanks man! Nope. No protectant. The body is PLA but everything else is PETG and that deals pretty well with heat and UV. We use PETG for outdoor antenna housings and it works great. Most people that have built these actually print them in full PLA and say that's what's most durable. I had black PETG so that's what I used. If needed I'll get some black PLA and rebuild with that.

Glad you like it! Not sure, I honestly don't have any tracks super close to me. Closest track is carpet and that's an Hour 30 mins away. Planning on running this rig there later this month. Also planning on building an outdoor grass/astroturf track at my house for day to day track bashing.

Hurrah! Another grass track coming.

Cutting edge build, Luke. Well done. -AC

ESC and motor arrived! Got everything test fitted and ready to be soldered up for the first rip tomorrow!

 

[luke66]

Didn’t get it soldered up today, but the ESC and motor make the car sit a lot lower:

As @DavidB1126 said: ‘Nice’

Also learned that the OG body was rubbing the belt so the weird spaceship body will do for now.

Testing a new version of the cooler body:

Did some other fixes that I’ll post later. Sleepytime for me though it’s a weekend coming.

Adjust the shock collars down. You have zero preload. I am going to assume it's going to run best if you get those arms level.

Possibly. If the arms are level the front end is pretty high.

Well you have quite a bit of squat on the front.

Hey! Just made an account when I saw you were building this, as i’m considering it. I wanted to ask if you had any battery recommendations/specifications? New to this hobby and want to make sure I get the right stuff. Thanks!

Any battery that qulifies as a 'shorty' 2S Lipo pack will fit perfect. (Unless it's a LCG, which I had to shorten the battery posts to fit) I use CNHL batteries cuz they're cheap and good.

Thanks so much, will look into those.

 

[luke66]

Car soldered!

Isn’t beautiful but it works! And so does the rest of the car! Took it out for a run with some old SCT tires.

Handles so well. Planning on taking it and a couple other rigs out for a carpet track day Sunday. I’m so ready to see what this rig is truly capable of.

 

[CertifiedMike]

Nice work!!!
I can't wait to hear how it runs on the rug!
Good luck!

 

[luke66]

So, got some new tires for bashing:

Bad news. This thing is fragile. Been working on making it tougher but without much luck. Oh well. Let’s see what I can do. Otherwise it’s pretty good still!

 

[Doom!]

I can't help it, I love the imperial storm trooper color scheme. those new tires look great.

 

[luke66]

Just discovered a crack in the lower chassis



REBUILD TIMEEEE!!!!!

 

[Doom!]

Use @Xraycer's plastic repair staple gun on it.
