OK, here's another of my dumb questions: Did that bulkhead behind the engine exist in the original? It blocks the airflow from the internal propeller & prevents it from blasting against that huge rudder for yaw control. Shouldn't it be open? With the contra-rotating rotors, the torque is already cancelled out. Or is it counter-rotating?
it took me very many sessions, maybe 50 or so, to be able to hover my real-life RC helicopter in the 90s. Hovering is more difficult than forward flight on a helicopter.I find it nearly impossible to balance that unbroken egg on a plate.
You might be right about that. But since I can't really do it in real-life because of my vertigo, I don't have much incentive. But maybe I should re-think that. If I could REALLY control a heli, I could probably keep it low-ish & in front of me better. Looking up and side-to-side really triggers the vertigo. I've never actually fallen down, but when it really hits, I can't even stand up. I've been known to crawl to the porcelain throne to worship. And I'n NOT going to post a photo of THAT, either.I'm saying this to encourage you to just practice. you seem like the kind of guy that can learn helicopter flying just by committing yourself to learn.
As bad as I am at flying helicopters, it flies pretty well for me. I found that the way the dual rotors independently destroyed themselves when I accidentally set it down in the weeds was pretty amazing. Each blade flew off independently in a different direction at slightly different times!
But I STILL don't understand the physics/aerodynamics of the yaw control. Is it the rotor wash reflecting off the ground, blowing horizontally over the rudder in ground effect? In forward flight (or backwards, I suppose - I didn't try that) it's obvious, but in hover, I'm confused. It doesn't seem like vertical rotor wash over the horizontally deflecting rudder should be very effective, especially when attempting to hover at higher altitude out of ground effect.
that is also the full-scale helicopter not the third scale model. I was going to make quarter scale, but the engine choice was looking like a saito FG73R5 and a painfully slow speed of mid to low twenty's.Thanks for the beta of the Flettner 282, it looks and fly's great, the only thing I would like to see is a bit more power/speed at the moment the most I can get is 55 mph in a shallow dive, the specs for the 282 says 93 mph max. (maybe that is in a steep dive)
This is more interesting than I thought it would be, @legoman . It sounds really cool, first, and the rotors look SO WILD, like they're just flapping all over the place. And it WORKS! It flies nice and gently, more similarly to an airplane than most helicopters, just like it seemed to do in the video.here is a preliminary flight model of the flettner. if something is out in left field with the rotor let me know. (headspeed, stiffness, etc)
I agree... I wasn't really expecting that. And I'm having more success with it than I've had with other helicopters. On top of that, it's fascinating to watch. THAT I was expecting.It flies nice and gently, more similarly to an airplane than most helicopters
