Not sure but Small Rotor bugged?

[Eagle]

So I was trying to do a quick build of a very small light helicopter I did everything right
I had the Gyro hooked up right I checked doubled checked and triple checked I had the small rotor on this one... I set it to 3 rotors I had my rear rotor set to 3. I had the tail rotor on the left hand side if facing the back of the helicopter. I had both tail and top Neutral. I followed tutorials twice making sure it was right yet everytime I tried to simply start the engine and gave it some throttle it twisted on the ground like a top the left.

I had everything hooked up. I did everything right I know I did because I copy pasted after the troubles the rotors on the default helicopter onto my model and hooked up two small pipes and it worked no issues.

Build a small heli hook up your Gyro use the Small Rotor and tail rotor and youll see what I mean. It just spins out of control like the tail rotor is on the wrong side but its not.

I am pretty sure that the rotors have been messed up in one of the latest updates. My large SkyCrane flew fine until a few days ago and suddenly cannot lift off, even when no cargo is attached.

I had some issues while building my first chopper where the collective would break after copy paste however I sorted it by cutting it pasting it again and merging the Rotor first then the body VS the Body then the rotor.

I know its a royal pain but if you want to give a shot it might be worth it to go into a custom game load in your Chopper Cut Select the Prop
Move it paste and rehook it up then click merge and click the rotor then the chopper and try it. For some reason it fixed my collective issues multiple times. On various versions of my chopper.

One other thing you can do is use the prop on the default heli select it, then move it to the back of the heli away from it and clear away all those other blocks you dont need then reselect it with COPY instead of move and or move either if copy isnt available and past that rotor onto your build then hook up the power pipes. Should work fine after that mine did.

My Helicopter uses the HUGE ROTOR which is no longer in the rotors library of the game from what Ive seen so if you would like to try the copy past trick of the huge rotor you can go to my steam profile and workshop items and get my heli and try the copy paste of that rotor onto your helicopter to solve your collective issues.

Matter of fact Ill give you a link standby.

IT SHOULD BE NOTED IM NOT PLAYING ON EXPERIMENTAL OR PARTICIPATING IN THE BETA BUILDS AT THE MOMENT THAT IM AWARE OF AT LEAST. I dont have modular engines.

Here you go heres my WIP heli that uses the HUGE ROTOR for you to copy paste over onto your build it works currently on my heli so it should work on yours.
Also I noted a few times that when I would copy a heli and move it to another build or something sometimes it would disconnect my Throttle Logic.

So verify your logic on the Gyro is all hooked up too!
My mini copter I was just building when I posted this did not use a PID I just had a Gyro

Works for me. Also not on experimental.

I think you might need to reverse your tail rotor.

Select the tail rotor with the selection tool (ctrl + click) then press the o key that should flip the direction that it pushes when the gyro hits it.

Also make sure the controls are going from your seat to the gyro and then from the gyro stabilized yaw to the tail rotor. If that doesn't work you can always post it to the workshop and someone will help.

As far as requiring more power I don't know if they may have messed with the power output of the current engines, or the power required for rotor lift. I just know I can lift off. And I'm using a single small diesel engine so it's not like it's a huge motor.

Edit: (I see you posted the creation just now)

Oh the one you posted isn't the one you are having issues with is it? Could you post the helicopter you are having the actual issue with?

Although weirdly enough it seems the jet engine doesn't work on the one you posted? Doesn't build pressure, kinda fizzles.

Alright Update.

I was testing this out with a jet engine instead of a gas engine and I was seeing some weird instability. As long as the inputs are all very slow and controlled it is fine. But if you give a sharp input it wobbles all over. And I think I figured out what was causing it.

The movement looked like when a washer has an unbalanced load.

Turns out my main rotor was one block off to the left, and even when I fixed that the center of mass point was not directly under the rotor. By fixing that and adding some weights to balance it out the problem minimized to the point of being unnoticeable.

So check your center of mass, make sure it's directly under the rotor, and that your rotor is high enough. Lower center of mass is more stable.

One additional note that with the Jet engine I had to make sure and keep the RPS a bit lower. The engine can go to over 130 and at a certain point the rotor seems to just self destruct. I'm using a micro controller for the Jet engine that works pretty well to control the throttle with a PID and dials the throttle back if it goes over pressure or over rps.

I have investigated this. The Update on the 13th of this month has broken the direction of torque thrust, the dev's reversed the direction so we must generate more rotation to lift.
Also we must set all trim to positive (it was negative trim), to compensate for the stupid decision.
I hope they change it back. Airbourne rescue now grounded :(

P.s Even Co-axial heli are being thrown to the left, and have lost lift.

I have two small helicopters that I got from the workshop. They worked fine several days ago, but now they won't even start. Nothing. Pressing starter and nothing, not even a noise.

Yes it seems there is definitely an issue with using rotors after the Update VS old builds rotors. But oddly enough it even broke older builds apparently. Thats an odd issue that would be fun to sort out Im sure for the devs since it affects both new builds using rotors that are new and breaks even old builds which you can use some of the old builds rotors on new builds and it works... odd.

As for the engine issue on your old workshop choppers Ive not experienced yet I only have the default chopper with ALT hold from the workshop.

So what Im thinking is to check the logic as I was saying I was having an odd issue where sometimes the throttle disconnected after copy paste. Maybe its not copy paste doing that.
Could have something to do with the update then.


As for Airborne Rescue Grounded... Try to see if pasting an old builds rotor onto your new chopper or even old one and hooking up the pipes sorts the issue but Save it as something else just in case it doesnt work and you wanted to keep that old rotor.

Maybe the Devs will fix the issues.

I think youre jumping from thread to thread too much getting confused lol.

You have already commented on the issue with my Helicopters Jet Engine. On another post "Jet Engine Dies while in flight" Im aware of the wobbling and off COM. I did what I could
but its a new build and Ive spend way too much time on it so Its flyable now and the engine works as well as the rotors as you noticed Im sure

I pasted my build not for an issue with the rotor but to help the person who replied to my post here with their issues of the Collective not working. I posted my heli so they could try to copy paste my helis rotors that I know work onto their older creation to see if it solves the issue.

As I stated in my post everything was hooked up I checked all of it multiple times
against tutorials on hooking up a helicopter from several peoples youtube channels.
I understand you're being thorough however but everything you said to do I did.

I knew there was an issue as stated because I verified everything was hooked up right.
So because I knew everything was hooked up right I copy pasted the rotors from other builds onto my new heli that was spinning like crazy "A very simple build heli". And it worked so I know it was NOT anything I hooked up wrong. I had everything hooked up right there is definitely a rotor issue and other comments here confirm that.

Thanks for having a look anyhow. That helicopter I linked to is still WIP and Im updating it as I go. Note that in the last update I forgot to save the change made to the search light button so the button isnt hooked up. However it runs it flies but I did the very last time I took it out for a long flight experience a shutdown of the electrics. That I have no clue on as to why given the batteries all read 1.00

Thats all under my existing thread for the dies in flight issue.

Anyone who has the same problem, I think we need to post these to bug report.
I made a bug report recently and no one (at that time) has reported the issue, let it be known so it can't be ignored :)
