So now that the size and material selection has been made for the Micro RC Track modules, being 1200 x 600mm plywood, a support structure will be required. This structure will keep the modules stiff and strong as well as ensuring the board don’t warp with any future features added to them. The drawing attached to this post shows the details for the structure which uses 70 x 35mm pine lengths to act as support beams around the perimeter of the module. The pine will be attached using 7G x 25mm counter sunk screws.
Dowel holes will also be drilled to depth that will support the lane barriers. The lane barriers that I will be making are using 42 x 19mm pine (dressed all round or ‘DAR’). More details on the barriers will be covered in a later post, but the intent is to is to have a through slot or oversize holes to suit 6mm dowels. As a result the centre of the dowels will be positioned 9.5mm in from the edge of the boards. The pattern for the dowels holes is shown in the attached drawing but the depth is not specified. The depth for the dowel holes is dependant on the dowels used, whether pre-made ones are used or they are cut from a longer length of dowel.
Not shown in the drawing is the location of the screws that attach the plywood to the support beams. The exact location is not really important but they need to be spread apart from each other and kept away from the dowel locations, so the best idea is to mark out the dowel locations before attaching the beam with the screws. The screws will need to be about 15-20mm in from the edge of the plywood. Each beam will have 3 screws, so one towards each end and the third should be near the middle without fouling any dowel locations.
Here is the drawing for this base module design as either a PDF or a JPG:
So with the module size being determined it was off to the hardware store to start buying some materials and test the idea. I have picked up 8 of the 1200 x 600mm plywood boards in 7mm thickness.
At the time of buying the boards I still was not 100% convinced in my head the size was right, so when I got the boards home I decided to do a little test. I layed out 5 boards, the minimum I think you need to make a track, and tested my Losi Micro Desert Truck on the layout. Given the track system is also modular I tried a couple of other 5 board layouts. Here is a brief video showing the results with three different layouts:
In developing the modular track concept the main problem I have faced so far is determining what size each module should be. For my mind the module size needs to consider:
The minimum recommended lane width for Micro RC cars. This should consider cars such as my Losi Micro Desert Truck as well as vehicles such as the newer 1:24 Losi Micro vehicles and Kyosho MiniZ buggies.
The available space of typical locations the track will be set-up. I am targeting my open plan living/dining room but other spaces people may utilise could be a garage or a basement.
Transportability of the track. I would like to be able to put all of my modules in my trailer, a 6′ x 4′ fully enclosed box trailer, to take to other locations. I would also like to be able to put a few of my modules in the back of my wagon or small SUV if I wanted to take them to a friend’s house who also has the same module sizes so we can make a bigger track.
Typical materials available. I would like to be able to utilise standard sized, cheap plywood sheets (or similar) from my local hardware store if possible. If not possible a minimal amount of cutting and wastage of purchased material would be desirable.
Set-up, storage and pack-up of the track. Let’s face it, I am doing this so I can have my own track but it will be in the way if I leave it out. I also want to be able to set it up quickly when I want to race.
Welcome to livingroomraceway.com. This site will be mainly about my build of an RC race track system for micro radio controlled cars. The reason I call it a ‘system’ is because the design intent is for the track to be modular and the design itself will be ‘open source’. This will allow people to modify my concept to suit their own requirements which may vary based on how they want to use the track, the space they have and the type of vehicle they use.
For my purposes I am intending to design my track based on using Losi Micro off road vehicles because, in my opinion, they offer the best bang for your buck. I currently have a Micro Desert Truck and I hope to try out some of the other Losi vehicles along the way. Kyosho mini-Z buggies are also considered in designing my track system.
I will blog here as my track build progresses so drop by from time to time and see how my track build going. If you build your own track, whether it is based on my concept or something different, also drop me a line through the contact page. I love to see other people’s ideas for micro RC race tracks.
