Re: Wheeled Vehicle B
Does anyone have the Wheeled Vehicle checklist sheet? I tried downloading it from the National Page but when I click the link it comes up ELG. Am I doing something wrong or did they mess up the National Page?

Re: Wheeled Vehicle B
Wait, I have a late start on Wheeled Vehicle, and how do I make it go around the #10 can!? I have no idea.

Re: Wheeled Vehicle B
Your vehicle will turn if you set your two axles at different angles. One way of doing this is making a 'hinge' between the front and back axles. You could do this by making your vehicle as two halves and connecting them with a single screw in the middle. Then you can loosen the screw, adjust the angle to one that works, and tighten it again. Since the track is far, the angle needed for the turn will probably be small.TourmalineKitty wrote:Wait, I have a late start on Wheeled Vehicle, and how do I make it go around the #10 can!?

Also, angling the whole car itself will help achieve the nice curve around the can and back to the mid line you want!bernard wrote:Your vehicle will turn if you set your two axles at different angles.

Re: Wheeled Vehicle B
Hi, my friends doing wheeled vehicle and need help. They are having trouble getting their car to go the correct distance. At the moment the farthest it has gone is 10 m. Does anyone have any advice?

Re: Wheeled Vehicle B
If the issue you are asking about is it not going far enough, your friends should consider making their car lighter. How heavy is it? My vehicle for Scrambler is about 450g which can be much lighter, which would allow it to run for longer. From my experience doing vehicle events, the smoothness of the axle's rotations also affects how long it can rotate for. Could your friends describe the setup of their axle and how it fits in the vehicle? This year I'm using a 0.125" diameter axle which fit in holes just a bit larger and it can rotate for a lot longer than when I did it with a 0.25" diameter axle.Panda Weasley wrote:Hi, my friends doing wheeled vehicle and need help.

Thank you bernard for your help! They have a wooden dowel 1/2 in. in diameter going through 3/4 in. hole that is in a thin piece of wood attached to the frame of the car. Is that what you meant?

Re: Wheeled Vehicle B
Yes, those are the details I was looking for. I've noticed that a thinner axle runs for longer. I haven't done a ton of tests on this, but my 0.125" diameter axle works much better than my 0.25" diameter axle from last year. If you use a thinner axle, maybe 0.125" diameter, you would probably want to switch materials so the axle is rigid (but this would depend on how long the axle is. I got my axles from Servocity, and they can be found under shafts.Panda Weasley wrote:Thank you bernard for your help!
