I have completed seven of the eight base modules for the micro RC race track and have finally gotten around to making a video of it, so let’s get straight into that…
It worked better than expected although the car wasn’t sliding on the plywood as it did in the earlier ‘Proof Of Concept’ test. I am not sure if that is because I have changed the trim settings on the transmitter, if the batteries are not getting a full charge or if having built up the track on the support it grips better for some crazy reason. The latter seems unlikely I would suggest.
My intent was to show a number of different layout options in that video but as you can see I broke a steering tie rod on the first layout so that was the end of filming. Reading around the forums I see it is possible to make tie rods for the Losi Micro Desert Truck and Micro-T using cable ties. I will give that a go as soon as possible and hopefully show you some more layouts before I start adding terrain to the modules.
Well, not quite, but the hard bit is complete at least. The lane markers have been slotted and mitred with the only remaining step being a coat of paint. I will show some details of the slots and mitres in a separate post.
Here are a couple of pictures that show a 600mm and a 1200mm lane marker coming together at a corner.
I plan on doing a little test run on the flat track with different layouts. After that it will be on to terrain and textures.
As the build progresses of my modular micro RC race track continues I have been thinking of the layouts I can have with the number of base modules I am making. My intent is to have a total of 8 modules but you can make a fun and modular track with as few as 5 modules as my proof of concept video shows.
Here are a few ideas for micro RC track layouts using 5 modules.
It’s been a little while since I posted here but rest assured, the Micro RC race track build is progressing. I have finished building seven of the eight base boards. The only reason I didn’t finish the eigth is one of the pieces of wood for the support structure was not straight. The base boards now just need the holes drilled for the lane marker dowels which I have done on one board as a test.
Here’s a few little pics of the lane markers on the base board as a work in progress.
The next steps are to finish the slots on the last few lane markers, mitre the lanes marker ends and add the dowel holes to the base boards.
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:
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.
