NOT stupid. I'm not sure I've ever seen it explained adequately without a picture, trick is has to be the right one to talk to YOU.

And its amazing how hard some subjects seem until you the last clue finally fits in place and makes large amounts of stuff just fit. I'm an engineer, strongly mathematically oriented since elementary school. Breezed through math till I got to calculus in high school. Then bang, while I could do the work by the rules, but it just made no sense because I just didn't get limits. Then one day years later in college, think it was during a physics class, BANG again, it just all made sense. Different explanation, different example. Years of math just fit and I could work from basic principles and solve problems without having a set method.

And it wasn't just once in my life, many times.

It states that the helicopter must be build from wood, paper, and plastic covering, but I saw a few designs with a plastic cups. Is that ok?

Illinois specifically varied from the national rule to allow plastic props. There is no national clarification allowing such a prop, so I'd say no.

Start by losing 3 grams FAST. Like Wright Stuff (or any flying event where duration wins) weight is critical and ALWAYS bad.

Possible ways. Can you thin your motor stick some. Same question for the blades. How hard would it be to replace the solid blades with a frame covered by light tissue? How hard to replace the blades with lighter balsa? Cut holes in the existing blades so only say 25% of the wood is left and cover holes on one side only with light tissue or light plastic covering like Wright Stuff planes.

Brief Tournament Results
43 Div B teams participated
25+ Div C teams participated.
Div B high time, 1:42, 5 teams above 1 minute
DivC high time, 2:00 plus

Based on the B results I think the arguments good to bring helicopter to B some day and not just C like planned for next year.

Stay tuned next year for even more helicopters in Sci Oly.

Great job to ALL teams who participated in the tournament today.

nice.
what place would 1:51 get in div c haha.
did any team go for the bonus? I would think not too many, and if they didn't they didn't do so good.
