helicopters, at center cyclic position, move forward.
Assigned, WishlistPublic


Found when taking off, all helicopters require no forward cyclic to assume forward flight other than than upwards collective.


Legacy ID
Advanced Flight Model
Steps To Reproduce

Take any helicopter
Come to hover an alitutde, establish auto hover, center cyclic
release autohover, aircraft assume forward flight.

Additional Information

During my re-test of this event, I believe I have found the issue regarding this as well as another report I made regarding helicopters turning when aft collective is applied. Upon a curiosity, I released the left pedal that kept the helo on a stable heading, and the helicopter ceased forward flight when it began to spin. Upon entering left pedal to stabilize spin, aircraft moved forward.

is incorrect! The helicopter sould't remain in hover in a center non trimmed position

In reality when the cyclic is in a center position you can't hover.

Is for that reason that before taking off you made the Hover Check: to TRIM the axes in a new "center of balance" to mantain the helicopter in perfect hover. Normally in counterclockwise rotor helicopter you can find the "cyclic balanced center" back and left.

Not going to use caps. Sorry you are partially incorrect. You ARE correct about the left lean, as you want slight left cyclic to compensate for translating tendency from the tail rotor thts not compensated for by default rotor tilt. However helicopter rigging (how the control links go from controls to rotor head) is intended to keep things as simple as possible. Compensating for wind or such yes can give you a slight directional input as well, but you should NOT by any means be able to simply apply collective and BAM you're going. The different models in game are also different, as the ghost hawk for example has such an exaggerated left/forward lean that the aircraft practically flips on you if you center the controls.

Edit: I will ammend that, I HAVE experienced aft cyclic needed to hover when I flew a bell 206, and it was because I had an incredibly heavy IP next to me who shifted the CG so far forward it wasn't even funny. But even in a light helo (8000 lbs plus fuel) aft cyclic wasn't overly needed. I certainly havn't seen it in the heavier airframes.

Sorry for caps.
ook i have no experience in the real world and then surely you are right.

But I can guarantee that in the simulators I use (in partiular DCS UH-1H Huey and Ka-50 Black Shark), that have incredible level of flight simulation, you can notice an heavy tendence for the helicopter in hover to go forward (or after for Ka-50) if you not compensate with after (or forward) cyclic. This tendence modifies according to the load.

An other thing I notice in these new helos is that usually antitorque pedals generate a lean on the wrong side. Infact normally you should have a lean on the opposite side you apply the pedal that must be compensated with same side cyclic. For example a counterclockwise rotor helicopeter need left rudder and left cyclic on hover. But in most A3 helicopters you have a lean on the same side and must compensate on the opposite one. Also the turning direction of the main rotor is not considered; eg Hellcat has clockwise turning but you have to apply a left pedal compensation!!! Is correct what I said? You also notice that?

I am myself a pilot who's flown a military huey, md hughes 500 and robinson r22. While there is "too much" input required to maintain a hover, it shouldn't be "centered" right off the bat. You've made like 4 tickets which mention this same "issue".

yep hellcat does do that, torque force should definitely be reversed.

Espresso I note that you're talking about light helicopters. For example I would agree with the xh-9 series helos that taking off is correct as it has a very slight forward lean. That does feel natural and is likely close to the light series helos you fly.

A ghost hawk is obviously a recreation of the blackhawk, which is just under twice the base weight of the huey at basic load, and almost 3x a hueys weight at max load. Heavy helicopters do NOT need this.

In relation to the game bug: At a hover, with controls centered, if you release autohover, (with or without pedal compensation) the helo goes into a rolling dive as it rolls left and noses way forward. Since wind does not appear to be affecting the aircraft yet, there is no good reason for this.

Just tested again, the fact the aircraft flies at about a 15-20 degree left-roll with constant motion to the left at forward airpseed (250kph) is indicative something is WRONG with how it's thrust is being directed. Helicopters don't LEAN in forward flight without pilot direction. They fly like planes.

Plus regarding multiple tickets: I'm flying the helos exactly as I would in real life. I take off, do a traffic pattern, and then attempt maneuvers out of my ATM. When things don't do what they should, I report it. Rotorlib is buggy right now. If you want minutia fixed, you report the minutia.

I am having trouble determining whether your comments (and others) reflect what kind of cyclic response you are using in DCS and FSX. Having tried config/controls (digital) vs config/axis commands (analog) in DCS, it seems that axis commands (analog) is preferable, more realistic. Arma3 is digital (except for mouse), how do you real pilots fly Arma3 (I am sure you fly DCS/FSX using the analog axes). To me it seems that analog flying is a lot different from digital flying, analog being easier. Do you fly Arma3 with the mouse and DCS/FSX in analog mode?
