3D-Printed 1/12th Scale Pan Car
Contents
The Mission
I accidently bought a 1/12th scale RC body: http://www.killerbodyrc.com/page/products.aspx?cid=12&sid=28 I really dig the Martini Racing design. Did I mention I also own two Lancia Delta HF Integrale in Martini Racing trim (sadly, only in 1/10th scale :) )? They are so gorgeous (don't let my girlfriend know...). Anyhow. I have various 1/10th scale chassis, but the really cool LC2 body won't fit 'em. I thought about converting a Tamiya F-10x, but then I decided to go for a newly built (printed) chassis - I always wanted to make my own RC car.
The Idea
- Luckily Daniel Norée did some awesome work on designing a 1/10th scale F1 car. I decided to use it as a starting point for my project.
- I needed to adapt it to the body size (170mm width, 235mm wheelbase)
- I wanted to use standard 1/12th scale wheels, since I didn't want to print them for various reasons
The Result
The Building Instructions
- Body:
- Killerbody Lancia LC2[1]
- First, print all the parts:
- Media:PanCar_2018-01-15_SCADs.zip - The source code in OpenSCAD-format, if you want to modify the design
- Media:PanCar_2018-01-15_STLs.zip - The STL-files for printing
- Get all the screws and nuts needed:
- M3 8mm screws counter-sunk
- M3 10mm screws counter-sunk
- M3 10mm screws cylinder-head
M3 12mm screws counter-sunk- M3 12mm screws cylinder-head
- M3 30mm screws cylinder-head
- M3 locknuts
- M3 nuts
- M3 6,5mm washers
- M3 setscrews 3mm
- M3 setscrews 20mm
- TBD
- Get all the ball bearings needed:
- 4 * 3x8x4 (front wheel hubs)
- 2 * 12x18x4 (rear axle)
- Get the wheels needed:
- 1/12th scale foam wheels:
- Front: 1/12 on-road foamies, I used TRC TM1212 45°
- Rear: 1/12 on-road foamies, I used GRP GTY30S 25°
- 1/12th scale foam wheels:
- Get the electronics needed:
- Standard 540 motor and matching ESC (a 540 can is a pretty heavy and over-sized, but I had it lying around…)
- 11mm servo, like Hitec HS-81(MG), Simprop SES-190 or similar
- ESC, receiver, battery
- Build:
- Screw drivers depending on your screw head types
Threadlock- Pair of pliers

The build
The Learnings
- Use a smaller motor - 380 type would suffice
