NC Science Olympiad: How to Wind and Fly your Helicopter

Good tutorial for helicopters event showing the proper way to wind your rubber band motor and connect it to the hooks, then let it fly! See how much the flight is improved after adding a pin to the top to keep the rotors from scraping the ceiling.

[linette4linny]

How to you attach the blades of the rotor to the middle piece in a way that forms that angle?

[kellstuh]

@linette4linny get a slightly larger piece of balsa and shave the corners down on each end to make the desired angle

[ncstateeddy]

How did yo construsts the areas where the ends of the rectangular wood frame meet the rotors?

[kellstuh]

@ncstateeddy Go to the link in the description to see close up photos of how it is made.

[Toonkid4life1]

@kellstuh at what angle did you attach the wings? we did 45 but no a 100% sure about it...

[Trevorapple]

actually figured that previous question out from your awesome website, but how do you attach the non-moving rotor?

[Trevorapple]

in your other videos you showed that you drill through one side and connect the rubber band hook to the propeller, is this done with both sides or just the top?

[sivartfart]

they see they see.....Kevin(the office)

[optimusprimerock1000]

a flying drill.

[wettfeat]

You should slope the rotors making the width thick at the center and thin at the end to reduce drag of the propeller and make it more efficient.

[naruto9561]

Does the stationary hook you made at the bottom frame hit the frame or spin freely without hitting the frame?

[pbackstreet]

what's the angle of your rotors? I heard 20 degrees is the best but how do you measure that and know how to put it on the wood?

[MrLabrat96]

What is the longest time you have had on this kind of design for a helicopter?

[Tough2luv]

Where could I find a rubber band like this one? Could you maybe point me in the right direction? Thanks in advance!
