Thanks #

This Radio Controlled Vintage Race car is by far the best RC I have published. The reason why it’s the best, is because of Trevor Innes’s dedication to make this the best it can be. Trevor spent countless hours figuring how to build this, from the choice of the TT-02 platform to how to incorporate the parts. Figuring out how to improve the drivability. How to print and what material to use to make this the strongest possible so it can be fun to drive for more than 5 minutes.

I also want to thank Paul, Trevor’s friend who contributed to this team effort by exploring some avenues and designing some experimental parts.

The reason we now have such a wonderful RC is because of Trevor and Paul. I implemented there ideas into the design.

Trevor also made possible the use of the Vintage Race Driver figurine at no cost to us by contacting the designer of this wonderful figurine.

Trevor as also put together a Fine Tuning guide that you must read before taking your new RC on the road.

Thank you to William Borrego he is the designer of the original Vintage Race Driver that he gracefully authorized us to use in the RC version. You can visit William’s Cult3D page or his vintage driver figurine

Notes #

You will need a printer with a bed that can print 220mm on X or Y axis.

This guide is different from my other guides. Since we are using many of the Tamiya parts for which I do not have CAD files, I need to use pictures for the build. Some of them are blurry, my apologies.

before every section where parts of the Tamiya kit is used, I will refer to the official Tamiya Build Documentation and parts number. Do not cut free all the parts of the kit since you will not be able to use the letter/number part number to find them.

When using parts of the Tamiya kit, I recommend you use the Tamiya screws that have bigger threads to screw in the injection molded parts.

Do not overtight screws.

Disclaimer #

This is a fast and heavy RC. It can cause harm if not handle properly. I cannot be held responsible for any injuries that may occur to anyone in the use of this RC.

Versions #

Current Version is 20230129

Fixes #

In this sections, will be listed the available fixes that are not included in the zip archives you may have downloaded.

There is no current fixes for this project.

Printer Calibration #

It is imperative that your printer is well calibrated. The bearing should be a press fit and removed just by pushing on it. It should not drop out or require undue force to install in the “Printer Calibration 5-10-4.stl” part.

You should calibrate your printer for every roll of filament, even for the same brand and color. If you need help to calibrate your printer see this resource: “Teaching Tech 3D Printer Calibration”

Here’s my procedure when I open a new roll of filament.

Chassis #

If you have a large enough printer, you can print the Frame One Part. You will have to choose between the Ferrari or Vanwall Exhaust

Printed parts required in this step

  • Frame front and Frame Rear OR
  • Frame One Part
  • Ferrari exhaust left and right OR
  • Vanwall Exhaust left and right
