Well then people who use whatever you make will be required to download KJR as well in order to use the craft. So at that rate why not just download a propeller mod or infernal robotics and attach a rotor to that. The glory about stock bearings, stock turboshafts, stock helicopters is anyone can download and appreciate them with a stock install of the game. A bearing made for KJR will not perform the same in the stock version and vice versa.

Azimech's stuff becomes less impressive after you realize that what should be a single prop engine fighter replica is actually nearly as big as a Boeing 737 with the part count to boot. Not saying that the whole electric thing is any more better or practical but everyone has their own things with their own quirks. That thing looks awesome mrmcp (Ps. Not really Azimech's fault though. Squad was the one that took away bearing functionality from those tiny wheels which requires the huge ones. That's why I have preferred making wheel-less bearings since.)

Well as you see the blades pull away on every helicopter I have ever made and especially so with the Chinook. It's just a matter of building the bearing and rotor strong enough. The blades pulling away from themselves is normal on any stock prop. You can always try adding more struts. But it sounds like your rotor and bearing are just too small. struts struts struts

You could try increasing the pitch of the rotor blades to slow them down and increase lift if they destroy themselves before reaching max speed anyways. Sounds more like a bearing deficiency. could you post a screenshot so I might help you? You could try using an engine setup like this if having them at the very tips are just too much. I use this setup on my super-small new helicopter. It's actually quite reliable for a single rotor helicopter and might share it later. If it is one of the thermometer hinge bearing'd helicopters you use that's probably the issue. As engine-tipped rotors require more reliable and sturdy bearings like pictured below.

Here are some rotor statistics for your viewing.

Wow. Some of these stats are more impressive than I expected. So it is confirmed using a helicopter like this is actually more efficient than just making a traditional VTOL with upwards facing jets. For 50kN of thrust creates over 200kN of force. Found on average the roll varies from 1100 to 1300.

Right. This was a long time ago. Like several game versions ago I think. I'll have to give it another shot and see.

I have looked there before but in experience those don't seem accurate because those numbers have a certain cap that they max out at that does not actually represent the accurate values. Also I would like to see what the rads are for those bearings in stationary flight at full throttle compared to what they would be like in forward flight at the helicopter's 40 M/S cruising speed.

I forgot. Dont have the fancy mods that tell like Azimech has. I have a video of them on full speed so maybe you can guestimate from that. But yeah pretty fast if you ask me. Engine-tipped rotors are usually far better performing than turboshafts which means a lot more weight speed etc. to deal with that requires strong and reliable bearings that are purpose built.

Yep. Even though you would think higher angles would equate to higher lift it also equates to far more drag. So increasing angles on rotor blades too much will actually make them less efficient and under-performing. Decreasing the angle of the blades the farther the distance from the center also helps. I have that rotor design incorporated into the Kinchook to increase efficiency.

Yep no problemo! Like I said earlier will always require tweaking and modifications based on the application. Love to see what people will be able to come up with. Usually minimized versions of this bearing do not fair well in my experience. It's suited to medium to large applications.

Yikes. Is that what I see to be... A single rotor stock helicopter!? Are you even Azimech anymore?

Anyways since this thread is so popular already i'll have to release my stock wheel axles as a sub-assembly too for people to make their own mega-trucks. But that is after I finally finish the base vehicle. Needs quite a bit of tweaking before I release it. Need to increase it's turning radius and reduce the part count and still build a hydraulic lifter to it.

I don't imagine being able to squeeze the rotations out of it that you can from your house sized wheel bearings though. Its just so much smaller and that alone will limit how fast they can go. So yeah you're right def. better for helicopter operations but I just wanted to show it's possible for horizontal operations if you get all the spacing perfect. You're better at this type of thing so i'm sure you can come up with something cooler just wanted to make sure to show it's possible. And exactly what Jim said. I was able to squeeze part count and use only 8 Ibeams for the bearing and it makes sense to increase this number if you want more high rpm stability. Of course you need to modify the design based on the application. And it should be possible since the base Chinook can spin those super heavy engined rotors super fast. You should post a download link to the turbo version so I can post it on the main forum page for it. All I think that you have to do to get that horizontal prop working is to increase the spacing between the ibeams.

How did I get my post to rep count? I obviously created 1200 alternate accounts to rep myself? Obviously. Not that it was like 10x easier to get rep on the old forums. And yeah usually I spend so much time building that takes away from time chatting. That's why the rep ratio is pointless.

Looks like it works just fine in horizontal operation. You just didn't space any of the parts adequately. Need to make sure you also increase the space between the Ibeams the smaller the attachment. With only 8 blowers and not even fully strutted can spin pretty fast and reliably. Sorry there.

It still looks better than my turboshaft version that I tried. Also I think it is the placement of the struts you added on the bearing that are snagging on those inner fuel-tanks. As you see on the chinook they are placed along the very outsides of the bearing. I have found they can "snag" and cause some glichiness when that close. But yeah as I said in the OP that they are designed for vertical operation but not necessarily impossible to use in other roles. I think all you really have to do is keep changing the orientations of the parts and you will find some success. How many parts is that? The default version is only 215. You also used the outdated version of the helicopter to try that on. Try putting those on the "C" version. And of course it will look prettier no matter what when you mod the game to get rid of engine smoke. Which of course makes turboshafts unplayable to new players with stock installs.

The bearings are now available for your own use!

I a very long time ago built an electric powered helicopter. Very ancient and from the stone age. Doesn't work in KSP anymore. But hey it was sure electric if you get what I mean?

Yep. Said it better than I would. The best and only attempt I had on a functioning electric aircraft was my ancient electrocopter. Which was pretty well performing. But of course the bearings it used don't work in KSP currently. Turboprops are far better performing besides their horrible fuel efficiency. I am stubborn when it comes to efficiency and part count so I just use jet tipped blades. Good for helicopters.

Well. You guys asked for it! So here it is! So I am now releasing the rotor bearings used to power my popular "Kinchook" stock Chinook helicopter replica to the public. They're very simple and low part count. A single probe core between two fuselages surrounded by Ibeams can hold rotors soundly in place under even the most stressful conditions. The base bearing subassembly is only 14 parts! But don't forget to add struts on your own holding the Ibeams and structural components in place as this is necessary to keep the bearing functioning stable. As you add power and weight to the rotors or spinning application make sure to add more struts! This is a must! for example when used on the Kinchook have 16 added struts each. This number will vary based on the application and sometimes may require no struts at all. I hope you enjoy this subassembly and can make your own awesome helicopters with it. They are less suitable in other applications but that does not make them impossible. The sky is literally the limit though. Unless you can make some crazy space helicopter. Download is beneath. Make sure to paste the file into the subassembly folder of the corresponding save file you want it in. Download: https://www.dropbox.com/s/lb821ilzmcft5fx/JRFB-Mk1.craft?dl=0

This is quite old. The download link may have been to mediafire. Which squad staff have decided to remove from the forum. I may get in contact with Beaver again soon and I can ask if he is available to updating this awesome design.

Yeah. I might release a sub-assembly of the bearing for individual use in other designs so the community can use them for their own projects. And of course Kin translates to family or kind. So it literally translates into family chicken or kind of chicken. For some reason I think that's fitting. Like chooks the Kinchook can fly but not very high. Since its a helicopter won't be going to space soon.

Too bad it requires a mod. It's Yuuuuuuuuuuuggggeeeeeeeeeeee.

[ and ] keys switch between the rotors and the main helicopter chassis. Since it takes time for the jets to change thrust and the SAS makes the helicopter very stable you can control the throttle like this easily without causing any problems.
