Here is this years entry. A flying saucer. Complete with an Alien and his dog to go under the clear canopy. (The whip antenna and 'coon tail was my idea)
I have to say, that I am pretty excited for this one. It will be a challenge to get it to run fast. Last year there was a little car called "breakfast on the run". It was a plate with bacon, eggs, and toast on it. It was suprisingly fast, as I remembered. This car will be similar in that there will be next to no wheelbase.
The track is wooden, with a fairly gentle ramp and transition and the flat section has a fair amount of length too. I don't remember thinking it was a rough track either. It seems to favor a conservative COM.
To construct it I think we will make it in 3 pieces. A box for the base and 2 rings (1 with a 45* bevel) then add a dome. I think a lid from one of the gumball machine containers, maybe.
My question for you guys is:
Wheelbase is 1.5" I'm not sure how stable I can make it.
RR seems irrelevant. Would you guys try it?
What about canting all 4 wheels to minimize contact with the rail?
COM well, there really isn't one, but I can get it low.
Rules allow for oil, how about Krytox 100?
Does this oil favor grooves on the axles?
