Interesting build. I like it. What scale is this. It looks big.
Is it the motor pinion climbing over the front gear that makes the chassis tip?
I am concerned about the high C.G.
Will you stagger the rear tires?
Look forward to seeing how this goes through a turn.
Can you do a video ?
Hi Martin. It's 24th scale.
I don't have access to any oval track and there is nobody racing these anywhere near me. This is a "for fun" build.
So being that I will only get to drive on a flat track circuit the whole design is meant to turn left and right, therefore no stagger of the rear end or wheel diameter or the top wing.
Not too worried about the motor being mounted high. There's plenty of room underneath for ballast. The speed is low as the pinion/gear ratio is done twice over; once at the motor and once at the rear end. My final drive gear ratio is around 11:1
The tipping of the chassis will be done mechanically by lifting the inside rear wheel and then the chassis will drop in that direction (like leaning a bike into a corner I am shifting the weight left and right above the center). So low grip is essential for this as the car has to actually get sideways for this to work. The fact that there is a lay-shaft under the motor all came about because I needed a center line about which to do all this rolling and pivoting. So although this is spinning when driven by the motor I also have slung the front and rear end on the same shaft. With all the shafts, axles and steering components I have used 18 oilite bushes so far to handle all the moving parts. I have used some to construct the front kingpin and steering parts just because they're easy (see earlier photo).
I will certainly be taking plenty more photos and making some videos of it running - that's many nights and very many coffees away yet though!
