THANKS!!!!!!!!!!!!!!!!!!!! I'll click that link as soon as I hit "Post reply"
I accidentally copied page 2 of that thread for that link. But I edited it so if you click it again, it'll go to page 1.THANKS!!!!!!!!!!!!!!!!!!!! I'll click that link as soon as I hit "Post reply"
When in doubt, please assume I'm joking. I will NEVER intentionally insult people I respect as much as I respect everyone here. And I DESPISE cheaters!You're a fun character. If only see could hear each other's voices, huh!
Okay coool.When in doubt, please assume I'm joking. I will NEVER intentionally insult people I respect as much as I respect everyone here. And I DESPISE cheaters!
You and I are both eager for legoman's thoughts, huh!I don't know why, but I almost never think about emoticons/emojiis. I use them occasionally, but they're usually an afterthought. I think it's another case of "old dog, new tricks." I think my grandkids could live on nothing more than emojiis & text. They might not need food, water, or... voices. And I'm sure I don't hit the "like" button often enough.
That video in your link is great. But I still can't visualize how torque is being controlled without causing roll and/or sideways flight with both rotors at identical RPM. OK, mixers... but which ones, how? How do you stop the roll while controlling yaw? Or vice-versa. It almost HAS to be using lift vs drag somehow, but I just can't see it. And does RF support mixing well enough to do it? I know that mixers can be combined, but I just can't seem to wrap my head around how to do THAT.
I actually figured that. And a lot of my comments were tongue-in-cheek. If you do select the one I want, I'd appreciate more detail of the WHY as you develop it - mostly to satisfy my curiosity, not because I ever expect to USE the knowledge. I'm curious about EVERYTHING whether it's useful to me or not. And I'm frequently surprised when THAT tidbit of information that I picked up 20 or 50 years ago seems to apply in a situation that doesn't seem to be related at first glance. I pretty much NEVER try to memorize stuff. Understanding WHY things work usually means I can work out the details that I have trouble memorizing. It works for me... and drove my teachers NUTS! Just HOW important was the date September 20, 1519 to the world? I had to use Google to find the exact date, but I've known what happened that day and WHY it's important for at least 60 years.If we have a tie I will tie break and pick one.
If it has a radial engine, it gets my vote!
Not to be argumentative, but will you be able to SEE that in the model? I assume it will SOUND right, but I like seeing the details, too.that's what's in the Chickasaw.
Maybe we will be able to see it. legoman shared this in another thread a few days ago:but will you be able to SEE that in the model?
both the chicksaw and the flettner have radialsIf it has a radial engine, it gets my vote!
.... will you be able to SEE that in the model? I assume it will SOUND right, but I like seeing the details, too.

I didn't realize that the Flettner was a radial. Maybe that fact will get it an extra vote or 2. I'm still hopeful.both the chicksaw and the flettner have radials
observations:
But... they have to run at the same rpm to intersect properly/safely. The only way I can think of to have differential torque would be independent pitch. How can they independently affect torque without inducing roll or sideways flight because of the differential lift while the differential drag applies torque? That's got me baffled. Then again, that's a BIG rudder. Maybe the only way to control yaw is in forward/backward flight. HhhMmmmm. Maybe that explains the prop! Back cyclic + forward prop thrust = hover. It's NOT rotor torque controlling yaw - it's airflow over the rudder. It took me a long time to figure that out. And I doubt that I could have seen it without that obscene nude photo. I didn't even know that the prop existed.it looks like maybe the rudder pedals have linkages that must manipulate the gear ratio of that gearbox to affect yaw.
thank you for setting me straight, Bill! you're so right. I didn't think about the differential in speed. I wasn't thinking at all obviously.But... they have to run at the same rpm to intersect properly/safely. The only way I can think of to have differential torque would be independent pitch.
