hey for balancing purpose put a probe which points up, controlling with that gives superior stability (bonus assign control to action groups) inspired by your reentry hack
@@vaos3712 Incidentally, when you want to hover, turn the SAS on and set the direction selector to surface mode and Radial-out. This way, the chopper will automatically return to a neutral thrust angle, so there is no lateral acceleration. Controls will be weird though, but I've seen you fly bricks. ;-)
Hey VAOS I am pretty sure that irl helicopters don't ever change the throttle or the rpm, but they only change the deploy angle of the blades to go up or down. Maybe you could try that sometime!
Actually they do. I thought the opposite which was the blades were at a fixed angle and the spin of the blades and how fast they were going is what determines lift. I later found out that it's a combination of both throttle and angle of the blades (a.k.a. collective) is what generates that lift as well as being able to roll the craft easier
@@vaos3712 yeah what I do is I have both the delpoy angle and the spin of the rotors on the main throttle and just slowly raise the throttle so it wouldn't just spin out on the ground and right about where you had your throttle set was when mine took with a full payload mind you
When you increase the pitch on a blades it slows down the engine so on the collective stick you rotate it to change the throttle while adjusting collective to keep it at relatively the same rpm. For ksp this this doesn’t matter tho cuz the motors
The blades are very lightweight and (in KSP) are not affected by the mass of moving air. You don't need 100% in "Torque Limit" (especially for such tiny craft). You can freely decrease this value (and size of the motor) as long as the “Current RPM” manages to catch up close to the “RPM limit” setting. This not only decrease the reactive momentum to fight with, but also very power consumption friendly...
Yo this is great. Much more practical than usual helicopter tutorials and I got to see mistakes before you figured it out which actually does a great job of explaining your conclusion. Thanks V
Hey VAOS, I recommend connecting this via a free rotor to some thing securely connected to the ground, so you don’t have to deal with spinning around and dying.
The card in the upper right-hand corner that sends you to a different video might help new viewers easily find the video you are talking about, great video!!
You almost figured it out. The way to do it is to bind the Deploy Angle of the main rotor blades ( en.wikipedia.org/wiki/Helicopter_flight_controls#Collective ) to the throttle and leave RPM limit at 100% for the flight. This is how it's done in real life and it gives you the most responsive controls possible. In KSP sadly deploy angle varies from -15deg to +15deg, so if you bind it to throttle directly to keep the lift in neutral position you would have to put throttle at 50%. The way to get around that is to use KAL-1000 controller. Bind the controller axis to the throttle and then tune the rotor blades position in relation to the controller axis position. Something like -1 -> +12 on the blade in relation to 0 -> 100 on the controller axis would work be pretty good, but you should play around with exact limits to see what works for you the best. Also couple tips: *Pitching the blade to full +15 deg is not a good idea because of how much drag it creates. +12 is about how far i would go for extreme situations when you need as much lift as possible. *You should pay attention to RPM readings mid flight and adjust the torque limit of the rotor to be as LOW as possible in a way that would still allow it to maintain max RPM even through moderately aggressive maneuvers at high speed. This will minimize the YAW instability and allow you to get the rid of extra weight. *Binding collective of the tail rotor to the YAW axis through KAL-1000 controller would be a good idea too. That would take some testing to figure out the best angles though.
Wait, what do you mean "learning"? I'm sure I've seen you use helicopter blades before. In any event, Silly Vaos could have loaded up my crate helicopter. :p 4:14 WHAT? NINE degrEES?!?!?! Dude. Dude. Oh my goodness. My standard is 3 degrees but I'm happy to go less if the machine seems overpowered with 3. Going with 9 sounds to me like one of the following was happening: the vehicle was overweight, the engine was underpowered, RPMs were too low, or you had too few rotor blades. 5:25 Yeah, I make my engines as small as possible (the engine mass slider) in the SPH because torque really isn't required on a helicopter unless you're trying to do stunts with it or lift heavy loads. I've made helicopter-like vehicles with the engine mass set to single-digit percentages in the SPH. Also, I saw you turn brakes down in the SPH, so that's good too. 7:11 Yaaaaaaaaaay! Progress! :D I want so badly to see you make a helicopter in Stormworks now.
He’s made craft with multiple rotors before, which is much easier because if you counter-rotate they cancel out each others’ torque. Can’t do that with a single rotor which is why it’s so much more difficult - you need the tail rotor to stabilise. That’s what he’s “learning” in this video.
I use the smallest rotors I can get away with. My Mk3 cargo planes look pretty funny with 6 big blades attached to a little engine on each side, but they work well. I think rotor power was nerfed a little for 1.12, or maybe blade drag was increased a little, but I'm not sure. Anyway, 1.12 made blades more forgiving; softer response and no more sudden stall.
You know that helicopters don’t adjust their controls by adjusting RPMs; that’d be too complicated and dangerous. Instead, they control the pitch of the blades. You actually want to keep the rpms at max, and use adjustments of cyclic and collective pitch of the blades to pitch and roll. The tail rotor should also use collective pitch to adjust the yaw deflection. Otherwise, this was pretty for the work accomplished
OMG it's the SAS that's controlling the cyclic pitch of the plades. Thank you so much Vaos for making this video and bring this to my attention. Knowing this will revolutionize my vtol design!
You can learn some from the rotors and controllers of the stock Jeb's Quadtaxi. I did. Just don't take the rest of the craft as a guide, it is absolutely horrible! Fit 4 more fuel cells if you don't want it to kill your crew.
hey vaos could you try make a attack helicopter with missiles and machines guns with looking like a stealth helicopter like the Comanche but with your own astetic design ofcause
Imagine a helicopter ssrt cose with the blades i imagine you have to go high and like fold them for areodynamics? And use the rockets to lift it thru the atmo sphere

I failed to show it, but there’s one underneath the fuel tank. 😎

RPM is typically governed at a set value. Throttle varies with rotor torque in order to maintain that set RPM.

nice job, if you put 2 motors with reverse rotation instead of the one in the queue it is more controllable
Do you mean counter rotating rotors? Like in the airship vid I made?
@@vaos3712 yes
Too easy! ;)
This way is quite complicated to me, so I usally prefer dual blade

Finally a solution to the land surveys, now we need to send one to another planet!
GET IN THE CHOPPER...
I really need to put some work into understanding rotors. Never managed to get anything to fly with them, not as a helicopter nor a plane.

what I've been waiting for, perfect
I Don't Have Breaking Ground DLC For KSP
You don't need it for propellors, rotors, and the KAL-1000 controller since... 1.10? 1.11?
Waw this video sid well, it would be sick to make class of different types of helicopters
Now I want to see full on replica of a black hawk
use KAL for the angle of the rotative wings to made a good and stable helicopter
helikopter helikopter
I've been thinking I need to turn on at least yaw of my helicopter's tail rotor blades. I just haven't haven't had time.
What about DUNA ornithopter?
Maybe
@@vaos3712 It can be quite challenging
Reminds me of the sikorsky r4
hey vaos could you try make a attack helicopter with missiles and machines guns with looking like a stealth helicopter like the Comanche but with your own astetic design ofcause
a good guide is on the Dzheo Games channel
imo just try to do a counterrotating one. Easier, more efficient and very high TWR.
Let's not talk about autonomy... It's technically infinite
how do i make the rpm limit to appear? i simply dont have it
Imagine a helicopter ssrt cose with the blades i imagine you have to go high and like fold them for areodynamics?
And use the rockets to lift it thru the atmo sphere
What mods do you use?
Is this available for 1.10
i got rid of my upside down problem
but now i cant stear
*Insert Indian man here*
I must be a hobo, since I can't get enough of these dumpster fires :)
LETS HO I GOT 100 LIKE
