I would also like to hear comments on that kit. The description does not say what size or rpm the motor is.
My thought is that it is a bit pricey. The best part about it is probably the instructions.
Look at the pictures on WIKI to get some ideas. Speed is not as important this year, so brushless motors and ESC's are not as valuable. If you chose to go metal rather than wood, Servo City-actobatics has most of what you might need at fairly reasonable prices for most of it.

I know that nothing on these forums is official and I have already submitted a FAQ, but I've heard that they often take a while to be answered and I figured I'd see if anyone on here had any insight. In 2.g., the rules say that the dowel must be "the leading part of the vehicle at all times." What does leading mean? Is it the forward-most part in the direction of the vehicle's travel or the part closest to the target point?

From the language, I think it's safe to assume that leading refers to the furthest most point in the direction of movement. So even if your car turns 90 degrees and starts going perpendicular to the track, the dowel will still be the forward most part of the vehicle relative to the vehicles motion.
Again this is not official and just my interpretation of the rules, so definately check out the FAQ when it's answered for the definite answer.
Speaking of FAQs on the national site, I submitted 2-3 questions last year around January/February and for some reason they were never answered. I resubmitted some of them a few weeks after first posting and still didn't get a response. Does anyone know why this could have happened? Is it often that questions don't get answered on the FAQs? I just want to be sure because the lack of answers to those questions ended up negatively affecting me at nationals.

That's happened to me before as well. I've also had some questions answered as an email but not posted on the official website which makes it difficult to refer to during a competition. Luckily it's never affected me during any competition yet.

Id agree with this. If you are worried about the dowel not being at the front of the vehicle during the run, just make the dowel as far forward from the vehicle as possible - wheel base has limit, not overall length

We sometime choose not to respond because we can't agree internally on a response (and hence decide to just leave it at the status quo). However that's pretty rare. It is definitely more common to respond via email but not post the response publicly. I wonder if something is going on with you email and they were caught in a spam filter? I get copied on all the Electric Vehicle responses, so if you can remember the general questions I can search my emails and see if a response was sent out.

I don't remember the questions I asked for electric vehicle, but I know that for Robot arm I asked 2 questions that did not render a response. The first was asking whether a pneumatic pump had to be within the robot box, or if you could have the pump outside of the robot base. The other was whether a hand/manual pump was allowed for changing an end effectors state if the pump was not used in any way to move the end effector (I believe I referenced certain rules in the question but forgot exactly which ones). The first question didn't end up affecting me at nationals but an answer for the second question would have allowed me to preform much better since parts of my device were not permitted to be used.

I checked my spam within a month of asking and didn't receive a response there. Is it possible I didn't go through the right procedure for asking a rules question? I went to the FAQ page and clicked on robot arm and submitted the question there (last year's version of this https://www.soinc.org/node/473 ).

I get copied on the Robot Arm ones too and I just searched my email and didn't find ANY questions from last year with the word "pump" in them. The form you link to is the correct one. Were you perhaps not paying attention and missing the CAPTCHA? If you enter the wrong thing it clears the page and prints in an orange box at the top that you didn't do the CAPTCHA correctly. If you do it the correct way, it prints "Your question has been submitted." in a green box.

I am confident that I recieved the "Your question has been submitted." message. I might have instead used pneumatic or pneumatics instead of the word pump.

I also get all the Robot Arms questions. The closest one from last year that I saw was "Can the competitors impart energy into the end effector without ending the
run? An example would be pulling a syringe on the control board to cause a gripper to close." Is that yours by any chance?
