Re: Helicopters C

Hello fellow Helicopter enthusiasts! Spent a lot of time reading on the forums but have yet to post anything, so here's to a first. I have a few questions to ask you experts that you can hopefully benefit me with answering. First of all, some info. We tried a 3 2 and then built a 4 2 configuration ...

Re: Unofficial Rankings C

I'll put down my top 30 here too, with explanations as well. 1. Mira Loma - I can't bring myself to put Harriton first, since I don't want to jinx them. I'm putting the defending champs instead, who really have seemed to come on strong between states and nats recently. 2. Harriton - Not much extra ...

Re: Can Arduinos be outside of the 25x25 box?

My coach is still concerned about having arduinos, batteries, laptop, and wires outside of the 25 x 25 box. Are there any officials that can confirm/deny for sure or are there any rule clarifications or something of that sort that straight out say that arduinos are allowed outside? Sorry for doubti...

Re: Can Arduinos be outside of the 25x25 box?

Also, I just realized that I am powering two of my servos through a usb connection with my laptop. Would this violate the voltage rule? Depends on what voltage your laptop operates at i believe. Can someone else verify this? The rules states that the internal voltage of laptops do not need to be ch...

Re: Pictures, Videos, and Scores

Wow, that's terrible. I hope it's run better at states! Congrats on doing as well as you did, though :) We (Mtn View) did manage to win the NorCal State Championship with a score of approximately -6.5. The event was run professionally with target point set at 11.3 meters. We were so happy we had no...

Re: Pictures, Videos, and Scores

At the Silicon Valley Regional yesterday the supervisor set the distance at 10.0m, but somehow make a mistake and placed the midpoint at 5.5m and set the actual distance at 10.5. We caught their mistake regarding the midpoint, but the supervisor would not change the midpoint to 5.0m, and we were fo...

Re: Electric Vehicle C

What are some effective ways to reduce skidding? We have tried balloons around the wheels, friction tape, and electrical tape, all with no avail. Make your vehicle heavier Making the vehicle heavier will not help because your maximum acceleration and decelleration depends only on the traction betwe...

Re: Electric Vehicle C

So I am new in this event with about 1 month and a half until states (My coach put me in here because of my success in other build events), and don't want to anchor my team, so hoping for a decent score. Most of the focus in here has been about programming the EV, but I have zero experience with Ar...
