Blackhawk up... well, I HOPE it goes up!

Whaz up?

So I decided to start building free flight model planes again after a couple years pause… well, in all honesty I never stoped building models, but the past two years I´ve only done indoor flying models that doesn´t look much like a plane anyway.

So… now I´m working on something I haven´t tried before, I´ve made a plane flight, I´ve made a twin engine plane fly, I´ve even made a ornithopter fly, but I´ve never ,ever made a helicopter fly!

Check out how things are coming together over here:

Sikorsky S-67 helicopter

Many pictures!, interesting discussions on mechanics!, free pop-corn!.. well, maybe not, but step inside and let me know what you think.

Gee… that one flew like a lead zeppelin, didn´t it?

I´m talking about the thread, of course; the Blackhawk seems to be able to fly quite well although I still have to trim it for stable flight.

Pics of the finished model over here at the bottom of the page:

Yeah, it’s a little late, I’m at work, and I’m tired, so my inner adolescent is coming out. That’s why I read your URL as www. smellingmyfarts.com/etc.

I hope your copter works well.

Psychoanalysis on aisle number 3! :smiley:

That’s cool, if a little nerdy. How long have you been building models?

16 years, or 2/3 rds of my life for what´s worth. I intend to keep doing it untill I kick the bucket, it´s a great hobby, build in rainy days, go out in sunny weather, meet nice people and burn off some stress; I can´t ask for more. :slight_smile:

Sorry, I was on vacation that week.

Nice model. How is it powered?

Rubber powered.

That´s the tricky part, because the rubber motor runs along the fuselage, but the power output must be perpendicular to that, so I had to build a transmission shaft that goes forward and then up to the main rotor; it´s called a Moore Drive and it´s explained in some detail in the first pages of that thread.

“Notice as it not so much flies as plummet.”
Somebody **had **to say that.

You´re a ba-a-a-a-a-a-d person, you know that? :wink:

The problem with the model is that it starts flying quite well and then it begins to oscillate back and forth; if I can cure that it´ll fly just peachy.
It´s probaly a matter of placing the center of gravity on the right spot.

No no, it does fly indeed!

And then it plummets… but I´m working on that. :stuck_out_tongue:

Helicopters don’t fly. They’re just so ugly that the Earth repels them. :stuck_out_tongue:

Ahem… :mad:
