Technically true, but you have a lot of room for error here because it also depends on your wheel-axle ratio and your car's efficiency (less friction from the wingnut, bearing, etc. = high efficiency). I have a lever arm of about 13 cm and I can go the distance just fine. I'm not saying that's the right way to do it, just that you can easily go the distance with a small car if you have a high wheel-axle ratio and efficient car.JasperKota wrote: ~2 feet sounds alright to me, you need the vehicle to be long enough in order to go the 3 meters forward, and 4 meters backward. If the vehicle is too short, the lever driving the vehicle would also be too short and the vehicle won't be able to go the distance.

Re: Mousetrap Vehicle C
Isn't 2 feet a lot longer than the 50cm or smaller requirement?JasperKota wrote:~2 feet sounds alright to me, you need the vehicle to be long enough in order to go the 3 meters forward, and 4 meters backward.

Not sure what a mounting point would be, but I'm guessing it's where you would mount your mousetraps?SciolyNewbieee wrote:Here comes a boatload of questions: Okay so the instruction said to cut 2x24 inch sides, but doesn't that seem too large? Would it be a problem doing 2x12 inches and if so, what's the benefit of having a longer/larger vehicle? They also mention something about a mounting point, what exactly is that?
24 inches is roughly 60cm

It's longer, but it's only the wheels that have to fit in that space.rafaelnadal wrote:Isn't 2 feet a lot longer than the 50cm or smaller requirement?JasperKota wrote:~2 feet sounds alright to me, you need the vehicle to be long enough in order to go the 3 meters forward, and 4 meters backward.

Re: Mousetrap Vehicle C
hmmm so the distance between the front and the back wheels has to be 50 cm but the actual thing can extend further?Unome wrote:It's longer, but it's only the wheels that have to fit in that space.rafaelnadal wrote:Isn't 2 feet a lot longer than the 50cm or smaller requirement?JasperKota wrote: ~2 feet sounds alright to me, you need the vehicle to be long enough in order to go the 3 meters forward, and 4 meters backward.

Re: Mousetrap Vehicle C
Imagine a 50x50cm square. You have to be able to drop this square completely over your vehicle without any part of the wheels touching the square. The non-wheel parts can be as large as you want.rafaelnadal wrote: hmmm so the distance between the front and the back wheels has to be 50 cm but the actual thing can extend further?

Re: Mousetrap Vehicle C
Anyone know where you can find metric sizes of aluminum/titanium threaded rods? All I can find are in inches.

Re: Mousetrap Vehicle C
How long did these take to ship? Do you have a link to your specific rod, since all the ones that I can find require a minimum of 50 pcs to purchase?RJohnson wrote:Here's where I got mine: http://www.alliedtitanium.com/products/ ... dStuds.phpAlex-RCHS wrote:Anyone know where you can find metric sizes of aluminum/titanium threaded rods?

I got a call a few days laters, made sure of the specifics of my order and now it's on its way. I ordered on 12/17/17 and it is scheduled to be here on 1/3/18. Obviously can't attest to quality of product yet but the service was very good.
Note on previous post: I have received my carbon fiber from Dragon Plate. Very happy. Does exactly what I need it to do. Would purchase from them again.
Edit: I just realized as I posted that the price disappeared from that page. I was billed $1.08 per inch.
