My Custom Built 1:24 Micro Crawler (Prototype)

[CrawlerSmith]

Just thought I would share with you all my prototype crawler i have been making, I havent got alot of pics but there is a video you can check out on YouTube. Let me know what you all think?

Spec:
1:24 Scale
Custom built brass chassis & axles (ruff prototypes)
Range Rover Shell
Twin Micro Geared Motors (30 rpm)
TSL Boggers on Slammed Xmods Rims
Standard ESC & RX
MG90 Servo

WEIGHT: 545g

So far I am not happy with the steering angles (too small) and I am not happy with the ground clearance (too low), but as this is my first ever attempt at building from scratch I am happy with its overall performance. A complete new chassis, axles and design is underway, once complete this chassis will be retired to the shelf.

WOW....:shock:

MOA on 1/24 scale?

Very impressive my friend

You must be some kind of engineer
to be able to Design & build something this awesome..........



GREAT JOB "thumbsup" AMAZING "thumbsup"

HAHA! Yeah me too! Didnt think the springs would articulate properly, but they do.

Thanks to all the comments so far. Im no engineer, I wish I was then it would be an even better design! This is my first attempt at making anything from scratch never mind soldering brass together, I have learned alot from the first design, the next one is already looking awesome... should be finished in a few weeks time.

Hey just wondering how you welded it all together?
What did you use?

And looking forward to see what your gonna do with the next revision

Just electrical solder and a minature blow torch pen (butane pen), using whatever small brass rods or materials I needed. pretty cheap to do actually and adds a lovely amount of weight to the crawler.

Wow nice didn't think that would hold up that well.
Wanting to do a scratch build of some sort. But ATM unsure how to hold it together and on designs. But yeah guess it should hold up nicely for 1/20th scale rigs?
Might have a look around for one
Think saw one the other day

Didnt take too long, a couple of hours here and there over a few weeks, maybe 10 hours total. The hardest part was deciding what bearings, gears & motors to use.

For my next rig I have found that alot fo the micro rc parts from other manufacturers are ideal. So I am using hubs, dog bones & aluminium rims from a Kyosho Mini-z AWD, Aluminium shocks from Hot Bodies for a Losi Micro Crawler. Gears (cogs) from HPI. And a few others here and there. I will post full specs when its finished.

The biggest shock with this rig was how well the springs worked. I based the articulation on fixed front & rear bearings attached to the axles (similar to the xmods articulation). You dont need much bounce on a 1:24 crawler. The springs basically suspended the chassis. Works very well, although im going for shocks and link arms for the next design.

Thanks for all the positive comments.
