A common path, as far as I interpreted it, means that he blade must spin in the same orbit every time. In other words, the orbit should be predictable.If that was unclear, (which it probably was) think of it this way.I have a question about the single-blade rule for 2014. The only thing defining rotors is in 3e. Rotors are defined as one or more blades that rotate on a common path around a vertical axis. What is meant by common path? Is it a circle in a single plane? Is it a cylinder? Is it a cylindrical volume? If one of the latter two, what defines the height? Has there been any discussion of this, or a rule clarification?
Yea I have the same question. I'm going to states nd my regionals didnt have helicopters.... so i have no clue as to what is considered a good flying time for a 25 cm helicopter, this year. Anyone know based on regional results?Hi, guys, I have done helicopters before (since last year) and i would say I'm okay at it. But I'm fairly new to the forums and this is my first post.
So my question is what is considered a good time for this year?
Last year, 30 cm rotor helicopters holds times that a 25 cm helicopter struggles to beat (atleast with mine)
Right now, im getting around 2 minutes and 24 seconds with my 25 cm helicopter, but i dont know how that is compared to others, as im going to regional soon along with state (if i make da team)
Background info: i live in Texas but i cant tell you my school
The brand i use is AMBROID. its all-purpose... its good bcuz it takes a while to dry so u can play around with it...but for some parts you need superglue.I joined my school's science olympiad this year, so I am relatively new to helicopters. I've gotten all my supplies, but the glue. I asked around, and some said model cement or super glue. However, I researched and found out that super glue is too heavy. Also, I am unsure about which model cement to get. All-purpose, or specifically wood cement?
So the big question:
What kind of glue is the best to use on gluing the balsa pieces together?
Actually, cyanoacrylates or CA or Superglue can be as light as model cement IF USED PROPERLY. See the following article I wrote a number of years back and still linked to the flying events.<SNIP background> What kind of glue is the best to use on gluing the balsa pieces together?
