Cool. Did you see my reverse/drive car?

Oh wow nice. That's some serious dedication! I hope it turns out well! Except it's a Focke Wulf FW-190

Nice. Looks smoother than mine but a lot larger. Are you going to attach linkages and a rotor head?

Thanks! Will try next time.

My Boeing 777 so far. http://imgur.com/a/qhYYh Sadly, the forum wont let me post imgur albums anymore. No idea why. The little black "i" just doesn't show up anymore More info on my original topic: Will post updates here instead as it is completed. Please give me suggestions!

That was you 3000th post. congrats!

The stuff on this page alone is mindbogglingly good looking! I wish I could build ships and submarines like yours!

Oh that shouldn't take TOOO long. I mean, space stuff requires less tweaking to make something work compared to a turboprop or the like. I mean don't get me wrong, i'm sure your thing is going to look amazing and have a ton of time put into it. I'm excited to see what it looks like.

Whats your constellation build? Sounds interesting.

Yup! Hey @Majorjim, your pretty good at this kind of stuff right? Maybe you should give collective pitch heli rotors a try. I'd like to see what you come up with!

I worked long and hard last night to produce this: http://imgur.com/a/yTNQq It actually runs quick smoothly. Though it is definitely not ready to receive any power from a engine. I am thinking about starting with 1 Juno at low speed and seeing how it handles when it spins. It has actual linkages and stuff which is awesome. I used thermometers instead of atmosphere thingies so it is quite small as well. Albeit prone to falling apart. One cool thing about control surface powered helicopter rotor heads is that you can control the throttle and stuff with trim for fine movement. This model also has only 4 individual craft, 1 for each blade, 1 for the swash/linkage assembly, and 1 for the main craft. I thought about how this could actually be applicable though in a aircraft, and I came to the conclusion that it can't. If you are trying to control the throttle with control surfaces, it will end up pitching the whole craft as well and vice-versa. We should make a pledge do include the basic controls(WASD Shift Ctrl) in the action group menu so we can fly stuff like this.

Current model. http://imgur.com/a/dxZ88 It doesn't work at all but it's progress XD This one is trying to demonstrate throttle control. By moving the swash up and down. Instead of tilting it for pitch and roll.

I am also well versed in the land of RC cars, planes, and helicopter. In that car your talking about, the engine is geared down significantly from that 42,000 to something that can be put on the ground. It's probably still fast AF but the wheel definitely don't spin at 42k RPM. I said it is impossible for a prop to spin at 50,000 RPM. Not the engine. Obviously props are much more directly linked to the engine than wheels. In the less complex planes, the prop is stuck right onto the motor's drive shaft. On the other hand, the Wren 100D Centrifugal Gas turbine IDLES at 42,000 RPM. It is used in high value/high performance large RC model aircraft and turbine powered helicopters. That particular engine has a max RPM of 160,000 which is unbearably fast. Obviously that is a whole different realm from piston engines, as there is only one moving part but it is incredible to say the least. For some frame of reference, the Rolls Royce Olympus Afterburning Turbojet has a idle RPM of around 8000. I don't know what max RPM is but it's not that much higher. Especially compared to the little engines which have a RPM range of over 100,000.

That's in centrifugal RC jet engines. I'm pretty sure a 50,000 RPM prop is impossible in any standard. I dunno why but I can't post images on here anymore. It doesn't give me the option too. http://imgur.com/a/f65Ty That's a helicopter tachometer. You can see the optimal RPM is around 400.

Helicopter rotor RPM depends largely on the vehicle. But it is usually around 400 - 450 RPM. So 51 rad/s is accurate.

Lol that's a good idea. I would pay to see that. Record it please and post it XD

Do control surfaces have a weight limit? If not, we can theoretically actuate anything using them. With no torque required. The best part is that it is a single part.

well you better make a 5 ton heli then.

That's why I said don't quote me on that

I would assume that has to do with the use of all those low-crash-tolerance parts and the insane amount of moving parts on it. But don't quote me on that....

Honestly, if we are going for realistically functioning helicopter rotor heads. Adding aesthetics can just reduce performance.

That would have taken me a week to do jees Seems like your building style consists mainly of REALLY offset parts. Cool.

See! I knew it!

Ya I meant tilt sideways. I guess that makes sense. But like I said, i'm basing my knowledge on my 1000 dollar toy. Obviously that is not the best model. That's why I said my helicopter has two swashplates with 2 linkages attached to the bottom plate and 2 to the top. Using a single linkage on your throttle axis can lead to unequal blade pitch and bad stuff.
