Mousetrap Vehicle C

[rafaelnadal]

I would avoid solid- it will be really heavy. Are you restricted to only one size that can be used? If you can make hollow CF tubes work, that would be ideal (assuming they won't bend).

Yeah i'm kind of restricted to 1/4" atm.

Does 6mm work for you? (1/4 in = 6mm)
if so try this: https://hobbyking.com/en_us/carbon-fibe ... 0x6mm.html
That's what I'm currently using.

Thanks, but I'm actually looking for a round tube for my axle.

I'm looking for a hollow CF round rod with a OD of 1/4" or 6mm bc thats the size of my bearings and wheel hubs. Unfortunately, I don't have enough money right now to get a CF rod + new bearings + new hubs...so I'm trying to find the right CF rod size

Today on amazon there are several pieces of 6 or 7 mm ID with a 8 mm OD. Lengths from 330 mm to 500 mm.
2 pieces for 14 to 20 dollars.

they also carry round tubes. That's where I got my axle.

How do people manage to cover the entire distance with banebots? I can't get enough string; if I use the length i actually need, i lose the tension. Ended up hurting my score really bad, so I have to switch back to CDs

How long is your vehicle? Ours is almost 50cm between the ends of the front and rear wheels, and we were able to make the nearly the whole distance with 2-7/8" banebots, with the very end of the distance (maybe 50cm or so) being carried at a pretty quick speed with momentum alone

What size if your axle, and your lever arm

For those using Banebots, which color are you using? We've been using orange so far, but I'm wondering if the car would benefit at all in terms of precision if we used harder wheels (blue). Also, Banebots are obviously a bit heavy in the context of mousetrap vehicles. We tried drilling out the wheels, but couldn't figure out how to make the holes even and keep the wheel balanced. Any ideas?

Currently using the blue banebots, but they are a little on the heavier side and we will probably switch to another type of wheel. If you have access to one, I would suggest using a laser cutter to cut out the holls in the wheels.

Do you mean laser cut part of the tread?


Also, does anyone know of anywhere that one can get cheap 35a(or below) tread, without a wheel? (I can make the wheel myself, and apply the tread onto it)

What size if your axle, and your lever arm

my axles are both 1/4" one is a wooden dowel, the other a steel threaded rod and i increased my lever arm to ~55cm recently to increase distance. Also my car length wheel to wheel is ~45 (my partner has the car with him right now i cant give exact measurements)

i also have ball bearings to reduce axle friction

EDIT: I could change my drive axle from a 1/4" wooden dowel to a 1/8" steel rod (i also found 1/8" bearings out of nowhere to go with it) to reduce the string needed by half which i think would solve my problem.
