Designs and Kits

[illusionist]

Wow, I feel pretty stupid. For some strange reason I thought the rotor diameter had to be 20 cm or less....

My school just bought the Helicopter 2011 Kit from Freedom Flight Models. Does anyone have any experience with this model? What should I expect from it? Any recommended modifications?

Is nice. Just be very careful building the jig, it's the most important part.

Any idea on what time i should expect it to give (assuming it's built properly)?

Below is a link to a video of a 2011 S.O. Helicopter I've designed and tested. I've also added a couple of pics to the Gallery. I am offering laser cut kits for 2 Helis for $40.00 plus $5.00 shipping. Complete with rubber, CAD drawn plans, tissue, flight logs, fixtures, instructions and my contact info to ask any questions needed.

I probably built mine too quickly, but I feel like I should be able to get at least 1:20 out of it with the right rubber and a flat ceiling. If I built it with enough time, I think 2 minutes should be attainable.

I've never done Wright Stuff before, but looking back on some older information about building planes, I see that the Wright Stuff planes all have detachable wings. Is this even feasible or beneficiary with a helicopter?

[chia]

You know, I was actually thinking about that. Depending on the design of your helicopter, though, it would likely be either unnecessary or impossible.
...Does it matter where on the motor-stick the fixed rotor is? (I'm assuming that's why you would want it adjustable)

[lllazar]

Yes it certainly does matter.

[chia]

Well, I know it does matter, but what's the effect of attaching it closer to the free rotor compared to having it at the other end of the motor stick?

[lllazar]

Well, from personal experience, my time goes up as i bring the rotor closer and closer to the middle of the rotor stick, but then not quite to the middle, my times start to take a dive for the worse. Take from that what you will, but i think experimentation is the key to figuring out exactly where to place your fixed rotor.

[chia]

Huh. I would have figured putting them as far apart as possible might work best (most designs I've seen do it this way).
I think more of an issue for me is going to be making sure the rotors are spinning on the same axis.
What do people have to say about having both rotors attached to the rubber? I've seen it in pictures and such, but I'm still not entirely certain how it would work. Both rotors would spin as a result of the rubber (in opposite directions), so the rubber is let out faster? Eh, I'm probably just confusing myself.
