Lmao he probably thought he used a straw for the axle


That's pretty funny. And yes, DarthBuilder is correct in both statements.

No, I’m guessing he thought you meant the lever arm.

Also, if I were an ES I wouldn’t accept a straw as a dowel. Have you had any problems so far?

Yeah, a straw is not exactly a "1/4" diameter or larger round dowel".

I haven't had any issues, but I guess i'll take a balsa dowel or something with me and replace if needed.

Why would a straw be an issue though? (per the rule change it needs to be approximately 0.25 in, but I'm using a thick straw, that is a little over 0.25.)

Being a thin-walled cylinder it is not a dowel. I think the hollowness is the issue.

No hate to anyone

But why would hollowness be an issue? It’s just to measure distance from the cup target and going backwards target.

It won’t affect the measurement, but the rules specify a dowel and in my opinion (and that of Wikipedia) a straw is not a dowel. I’m just saying this because I don’t want you to get tiered for a dumb reason.

Yeah, I understand your point. I'll have to go buy a dowel before Saturday now. (on top of everything else I have to do lol.)

Also, in that case, isn't a 3d printed dowel not a dowel either?

I think if it’s filled solidly then it probably would be considered a dowel by most ESs. If hollow, more of them would take issue I imagine.

If you aren’t able to buy a dowel in time, a chopstick, or even a pencil, might work on the fly (but a “real” dowel is probably best to avoid any issues with the ES).

Would a 20 pound fishing line and a 6 pound fishing line have much difference on how many reactions it can take in the same vehicle? Like I sued the 6 pound line which was thin and it took all of the rotations now the 20 doesn’t take all the rotations. Is this due to the thickness?

Depends on wheel size, and length of lever arm. Will elaborate later, have competition on Saturday, no time,

Is there any penalty for going outside of the lines? If so, how much? My car does not travel straight and its going to be very hard to fix.
