3D-Printed 1/12th Scale Pan Car

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
• 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°
• 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 Learnings

• Use a smaller motor - 380 type would suffice
