This is incredible!! I have one suggestion though. You currently have the Steering Hinge (that connects the rotor assembly to the helicopter body) rotating forwards and backwards (you have the controls set to "u" and "o"). I assume the purpose is to be able to set the blades to have a constant tilt creating constant forward motion. This is a brilliant assembly, and exactly how a real helicopter works... EXCEPT ... thanks to angular momentum, forces applied to the spinning blades take effect 90 degrees after application. This means that when you tilt the blade axis "forwards" it causes the helo to bank to the right. If you rotate the hinge assembly by 90 degrees, you could achieve rotor tilt that propels the helo forwards and backwards.
I'll give it a shot and let you know.
Unfortunately, I can't think of a great way to tilt the rotor in both axes simultaneously and still have such a sturdy setup. Then you'd have a TRUE helicopter.

Of course, maybe this game doesn't take that into account at all anyway. It's hard to tell when it swings all over the place, lol.

Unfortunately, I can't think of a great way to tilt the rotor in both axes simultaneously and still have such a sturdy setup. Then you'd have a TRUE helicopter. The effect you're talking about focuses on where THRUST is applied (not tilt), So...in real life if you wanted a helicopter to tilt forward, you would apply more downward thrust on the right side, because that thrust would only be applied 90 degrees later. As far as I'm aware the tilting of rotors isn't in the same boat. All that said: this is a game, and it doesn't even begin to correctly simulate aerodynamics. The effect you describe just doesn't exist in the game. The rotor-tilt I added to this design was intended to allow the wings stay relatively level while the helicopter moves forward...because otherwise it becomes very unstable. It's also there to help keep the main rotors from hitting the tail every time you press the button to go forward.

I see. It flies great, just takes some getting used to. Awesome knight on horseback, btw.

When I try to use it, the top rotor immediately becomes dislocated after giving it a little thrust. Is this something I'm doing by maybe forgetting to press a key? Is there a way to fix this?
Thank you

Nah. just a bug of the game. If you're holding a button when the simulation starts, it increases the chance of something breaking to 90%. Just don't press anything till it hits the ground and settles. If you're getting extremely low FPS, that can also cause the physics to get weird (and increase the chance of breakage), so slow down time a tad and see if that helps.
TBH, sometimes I just tap spacebar twice if I get a failed start (I'll know immediately after I press shift...if something falls off) to quickly reset until I get a clean start.

Alright, thanks a million. I guess that getting too excited to download a working air vehicle after I discovered all of mine don't work. Thanks for sharing a great design with us.

Excellent work, the helicopters just looks amazing.

Hi Praesumo! Absolutely love your stuff fella! I've been going back through you posts and trying out your machines! Lots of fun.
Looks like the helicopter has a weight issue in the new update, you design right now gains very little height before returning to earth!

Amazing as usual. I linked to your chopper in the Modules thread. If you'd rather I didn't, let me know and I'll remove it.

Looks like the helicopter has a weight issue in the new update, you design right now gains very little height before returning to earth! Really glad you're enjoying what I posted! That's exactly why I posted everything! As to the helicopter not climbing very fast (I assume you mean the Apache?) that's intended. It's designed to pretty much hover while you're holding shift. Then you're supposed to use the pitch-control on the large rotors to climb or descend. The controls for those are 1 and 3 (I think). Left hand controls height, right hand controls everything else. Do let me know if the problem persists, and I'll re-upload the file to make sure it's good. The one in my save-folder works just fine.

I've been working on a stable helicopter that didn't use any cheating flying blocks. Your rotor design helped me get off the ground so wanted to give a huge thanks. HELE3.bsg (10.67 KB) Yaw numpad6/numpad4 Hover numpad5 Lift numpad8 Pitch up/down roll left/right

that looks pretty epic, seems like it might take quite a lot of skill to fly, hmm
