1st at RI State Competition :D :D

Caliper acted up again :roll: (pro tip don't ever use a harbor freight caliper :evil: ), steering was way off. The buggy traveled in a straight line, but it was angled for a nice bonus, so it hit the wall... both runs... my caliper setting was right, but it just didn't work idk why...

Anyways 1st run when it bounced off the wall somehow it ended up 18 cm from the point, and 2nd run was 26 cm off. Definitely could have been better with two regular runs, but still got the dub lol.

Wow! With that kind of luck, I would definitely buy a PowerBall ticket tonight! Congratulations and thanks for the word on the Harbor Freight caliper. We were thinking about switching to caliper steering over what we are using, but too much involved and not enough time to gather accurate data before 4/6 this weekend.

Thanks! I used this caliper:
https://www.harborfreight.com/6-in-dial ... 63730.html
So every rotation of the dial is supposed to be 1/10 of an inch, iirc, but that's clearly not happening according to the scale intervals on the caliper itself. For example when it is measuring 1.56 inches, the dial might read 1.59 or 1.51. Actually it's way worse than that, but it's just hard to explain how bad it is. I was showing the local high schoolers how caliper steering worked, and doing that could have messed up the readings? Doesn't make sense lol. Also the "durable plastic case" has split in half...

I don't think calipers would be usually inaccurate, I'd think it's just wear overtime. Considering the stopping of the car puts a lot of stress on the tooths of the caliper, it wouldn't surprise me if a few wore down or broke.
Are the teeth plastic or metal?

Not completely sure about the material of the teeth (metal I think), but I assure you the caliper is really really bad - I can show you in person at nationals if you would like. In retrospect, it probably had something to do with cutting off too many parts off of the caliper with an angle grinder and because the high school teacher "took it apart for research purposes". But no worries, I have attained a much better caliper for my nationals buggy. :D

Nicely done! Crazy they had it set up in such a narrow place. So you didnt even need any bonus to win state? (Assuming no bonus as it hit the wall). You going to nationals?
