Significant Pitch-Up without trim

[kingfish]

Title says most of it. When the stick is centered, the helicopter wants to pitch up to 15+ degrees nose up. The manual makes it sound like if the CG is balanced, you should be able to just increase collective and go straight up. If I do this, the helicopter tilts back and ends up sitting on its butt. I find i have to trim the cyclic forward about half of its total throw to get the helicopter to behave normally (i.e. letting go of cyclic makes it roughly hold even).

 

This happens with both my startup and the auto startup, and with the autopilot channels on. Auto-hover without trim immediately pins the cyclic as far forward as it's authority allows, but it is not enough and I end up either sitting on my butt again or moving backwards and down if I'm already in the air.

 

Is this how it is supposed to be, or am I doing something horribly wrong?

Well I can say that is pretty much how it is, one reason I don't even bother programming trimmer reset to a joystick button, as I never want to reset to it's default value during a flight.

 

May have something to do with not using FFB stick, I am not sure. First thing I do before taking off is press and hold the trimmer button, hold a little forward pressure on the stick, and adjust my attitude as I take off.

This is how it's suppose to behave. Always apply forward cyclic and trim once to "hold" the cyclic in that position.

 

With practice, you can brake when taxiing using small cyclic inputs as well as going reverse..

Mine does that... seems natural to me.

 

When you're ready to take off increase collective while holding trim. The front will lift. Keep adding collective, move cyclic forwards, repeat, repeat, repeat until you're barely on the ground.

 

Release trim and cyclic.

 

Now you're trimmed :).

 

You can take off however you like. Forwards, backwards, sideways... Have a ball.

 

Once you do it a few times it only takes like .5s

Pretty similar for me, as others have reported. I do just a bit different, after startup I hit the trimmer, relax controls and then just apply a wee bit of forward cyclic pressure when pulling collective. Completely controllable as expected.

I read that during the cold war, engineer Leonav Titsvonavich was granted an apartment which was below his station by the former Soviet Government. In retaliation he made it impossible to calibrate the KA-50 cyclic to zero relative pitch. When you go into the calibration settings in the ABRIS it simply says "Pitch calibration intentionally lacking several square meters." He defected to the U.S. before the KA-50s maiden flight.

 

He now lives in San Francisco and works for Walt Disney Corporation. He has a very large dacha and a three legged dog named Kamov.
