Detailed JK Build from Europe - Scale-Detail-Mania
Hey guys,
I'm Jakob from Austria (a tiny country in the alps). This is my first ever post here but I read a lot and took some great inspiration off this forum!
A couple of weeks ago, I went to my friends birthday party when I discovered his brother's Tamiya trucks (1/14). Having had RC cars myself when I was a teenager, I was immediately hooked (again) by the RC thing and I started daydreaming about a scale crawler. The very next day, after some research I ordered an Axial SCX10 Jeep Wrangler Rubicon
And I couldn't have been any happier since! 
So this is my return to the RC world after an absence oft about 12-13 years
Now I want to show you the results of the last couple of weeks’ work:

The Basics:
Chassis & Body: SCX10 Jeep Wrangler Rubicon Unlimited
ESC: Carson Mtroniks tio RockC 35T

Gears: 13T pinion and 87T stock spur gear => 87/13 = 6,69:1 gear ratio
Servo: Savöx SW-0231MG Waterproof
A picture I took, the very first time I ran this truck on the trail

So… What did I do to customize this little beast?
Performance Upgrades:
Front battery & rear radio box mod
You all know this mod and I quickly found out, why everybody does it
It works and it improves crawling performance!

Simple steering mod (m3 nuts)
A guy I met at a local RC store told me about this mod: Add one M3 nut to both ends of your steering link (between your link and the ball end). It improves the stock steering performance significantly, although your tires point away from each other after this mod. Don’t forget to add an M3 nut to your servo link as well to account for the extended steering link!

Wiring & Plugs
When I saw the Tamiya plug on the Nvision battery, I was kinda upset. How can you sell a battery for this price and put a Tamiya plug on it? Now I’m happy that the battery had this plug because it made me rewire the whole build and it made me learn how to solder!
I removed most of the plugs I didn’t need, I removed the on-off-switch for the ESC and I added T-plugs to my battery and and ESC. So the Tamiya-sh*t-plug has it’s good sides as well.
Then I used some mesh tube to tidy everything up and keep the wires protected and organized.
Beadlocks
Rims! What a mess! There are so many out there and the prices range from 18$ to over 100$ for two… I opted for the Boom Racing EVO 1.9 High Mass Beadlocks just because they were cheap and I liked the look. I’m happy with them except for one thing: If you get them DON’T USE THE INCLUDED PIN-SCREWS TO BOLT THEM TOGETHER! These screws are the worst. I ruined two of them just by trying to unscrew them when I got my new rubbers and it took me about 3hrs to remove them. I replaced them with stainless steel M2 hex screws and now everything’s fine (but boy these screws were expensive… 1$ p.pc.).
Tires & Foams
I started out with the stock Maxxis Trepadors and the stock foams and it was okay… The tires are good, the foams are too soft (or my rig is too heavy). Two days ago I finally got my Pitbull Rock Beast tires with their two-stage foams and I can’t wait to try them out (I’ve got a cold right now, that’s why I didn’t go out to try them today…). The Rock Beasts look amazing and they’re said to perform really well. I’ll let you know what I think!

Shocks
I really like the JK’s stock shocks but I was looking for something more extravagant and scale… I was thinking about mods to separate spring and shock but I decided to go with internal spring shocks, which is the next best thing to me. I got the Boom Racing Boomerang Type I 100mm shocks and mounted them upside down. I think this looks great and it handles well on the trail. Included in the box are three different springs and I’m using the hard one in the back and the medium spring in the front. Additionally I just filled them with 30wt shock oil and I’m curious to find out how this affects handling.

Rock Slider Electronics Plate
I used some leftover polycarbonate from the body to create a plate that mounts onto the rock sliders to hold my ESC and the NVS in order to lower the CG.

Weight
I added some metal bars I found in my dad’s workshop as additional weight and it improved handling. My jeep weighs 8.4 lbs / 3.8 kgs ready for the trail.

Now I want to show you the results of the last couple of weeks’ work:

The Basics:
Chassis & Body: SCX10 Jeep Wrangler Rubicon Unlimited
ESC: Carson Mtroniks tio RockC 35T
- a waterproof ESC that performs quite well[/INDENT]
- It could be a bit more sensitive in the low rpm region
- A hell of a motor
- Enormous torque
- Very smooth running
- great breaking performance
- although: steep descents don’t work so well with this ESC/motor combo
- I also tried the Tamiya 35T crawler motor, but it was too fast for my taste. I like it slow

Gears: 13T pinion and 87T stock spur gear => 87/13 = 6,69:1 gear ratio
Servo: Savöx SW-0231MG Waterproof
- a good servo so far
- 12kg/208oz torque (it’s not crazy much but enough for now)
- and it’s waterproof!
- winch on the 3rd and lights on the 4th channel
- happy with it
- looking forward to try out AVC with an on-road car at some point.
- good battery
- comes with Tamiya plug, yuck...
