Ka50 uncontrollable

Whenever i try to take off the nose goes straight into the air, when i try to land i am constantly fighting that piece of scrap because it moves all over the place. when i try to trim i always over trim and need to correct again so i can never fly straight :music_whistling: It seems like the trim doesnt work as it should because it is way too inaccurate. Does anyone have some tips?:helpsmilie:

Your nose goes up in the air because you are not trimmed for flight, you are trimmed for staying stationary on the ground. Before takeoff, either apply gentle forward cyclic, or trim forward.

 

Regarding tips for overtrimming, well, don't overtrim. :P You generally should never make big trim inputs, just walk it forward - deflect cyclic a couple degrees forward, press trim, if you need more, keep doing it until you're fine. This way, being late or bungling the re-center will not hurt you as much. Trim works fine as long as you do it right, but it does take a lot of practice.

I sometimes have this problem but practice helps a lot. I trim forward about 1 diamond on the CTRL+ENTER input window and then look out at a 10-11 o'clock angle to get a feel for the movement. Then slowly raise collective and make very small inputs to the cyclic and pedals, if all is well a bit more collective up to 5m, then bring up the landing gear and engage auto hover.

 

It probably took me 10+ attempts before I started to get it right. The trick is small inputs to stabilise and using a trim method that you are happy with and understand. Personally I fly the KA-50 with more subtle input being used on the controls than relying on trim and autopilot too much, I find I get a better feel for things if I over use trim then I always end up fighting it.

Also if you got crappy joystick like I do it's a good thing to tweak your axis a bit. Add a small deadzone to the center, little curvature so its more precise near the center and saturation to get smoother control. It helped me a lot. And then just practise. Flying in sim mode requires really good (precise) control. About the trim. I trim with the "trimmer center mode" on. I stabilize the heli, press the trim button, hold it until im satisfied with the direction of flight (few seconds), relese the trim button and then gently move the stick to the center. Don't do any quick movements, that usualy ends bad if you don't know what you are doing :-)

Important; don't forget to put on your autopilot stabilisers before lift off.

Right hand lower panel, '4 Blue buttons', light them up.

What can I say, welcome to flying helicopters. It's a lot of work and you will constantly make micro adjustments with your cyclic unless in full autopilot in cruise speed. A common mistake is to make big adjustment and then over-correct. I find that a lot, especially in people used to fix-wing. Just give a small nudge on the cyclic in the direction you want to go and wait for half a sec to let it stabilize, then nudge it again.

 

It also sounds like you may be too rough on the collective during take-off. Ease the collective up slowly and see where she want to go. You MUST be in perfect balance before the wheels lift off the ground, but unless the trim is way out you should not need to trim for this. You'll just be too busy trimming instead of controlling your helicopter. Correct for attitude and drift and try to hold a stable hover @ just 3m.

 

Make the habit of looking at the horizon during manoeuvring, hover in particular, do not let your eyes fixate on the pad or other ground objects during landing, take-off and other precision manoeuvring.

 

Hope that helps (someone) ;)

Trim

 

A simple way to take off from the hover is to:

 

1. Make sure your brakes are set

2 Put the cyclic forward a little, then trim it there.

3. when you take off you won't pitch up, but will either be in a trimmed hover or a slight pitched down attitude. It works pretty well this way. It's easier then trimming after you first lift off, as this results in a nose up attitude unless your really quick.

 

*note; This helo would benefit greatly with a beeper trim. This would allow you to "beep" the cyclic forward with a cyclic mounted button vice just setting the trim using the entire cyclic control stick. Not sure why the designer of this helo did not do this, but hey, they are engineer's......

I've seen a lot of posts about BS2 being more difficult, about the improved graphics and about it being more demanding on your PC. I haven't seen any that link the 3 things together though.

 

 

 

I flew BS1 for a while, installed on a PC that was just about able to handle it. When I got into battle situations, it became unplayable but for practicing flying and learning the systems, it was fine - and this is what I needed to do. I got to a point where I was quite good at flying it. A typical frame rate would be about 15-20 FPS.

 

 

 

A few weeks ago, I purchased BS2 and really struggled to fly it. I found I was fighting with the controls and autopilot the whole time. Trimming was a nightmare too. After a while, I started to suspect it was more than me being out of practice.

 

 

 

I now have BS2 installed on a new PC with a decent processor and graphics card. The difference is incredible - not just in frame rate but in the way it controls too. It is very responsive to my input, very smooth to fly and trimming is really easy. It is a real pleasure to fly.

 

 

In my experience, the frame rate is not only a reflection of the smoothness of the graphical output but also its response to user input. This may also be true for some other people with older PCs. It could be time for a trip to PC World!

Stabilizers + trimming + practice + patience ...

[Kraz75]

Apart from a good joystick setup, I always maneuver using Flight Director now.

 

Once I discovered that it actually changes the flight dynamics it's made flying far easier for me. I used to think it was only a HUD symbology that you followed, but it actually removes the computer control somewhat and is extremely useful for manual flight as you are not fighting the trimmed controls. Trim is still there and used, but the effect is far less. You still keep the Bank, Heading and Pitch buttons on though (usually always).

 

To be precise the manual states ... "Flight director mode button. Disengages autopilot automatic angular stabilization (except for dampener function)..." page:6-69 or 143 in PDF.

 

I turn FD off when I've settled into a flight patten I want to maintain, usually when enroute to a waypoint or when coming to a hover as it helps stabilize things more.

frame rate is not the problem in my case (average of 120 fps) but i think ill be much better at flying when i get rudder pedals and trackir because now i only have a warthog.:cry:

[weasel75]

Sorry, mind me asking, but what kind of PC-hardware are you running?

120 fps???

OK .

 

...so you obviously use the whirlpool for the water cooling.
