Frag Posted March 24, 2022 Posted March 24, 2022 Hi guys, I did notice that the Apache commonly hold a crabbing stance even with 0 wind configured in the editor. Is it normal? I would say that a bit of crabbing should take place when we change direction, but it should correct itself with the air flow after few hundred meters. Am I missing something or it is normal to have the chopper behaving this way even with no wind?

I also quoted his post in the bug reports section under a similar post about crabbing. https://forum.dcs.world/topic/296438-advice-on-aerodynamic-trim/?do=findComment&comment=4924727
fjacobsen Posted March 24, 2022 Posted March 24, 2022 Note that in order for the Tail Rotor to keep You on a steady heading, You need to add left pedal, which will push You sideways, which again requires some left cyclic. | i7-10700K 3.8-5.1Ghz | 64GB RAM | RTX 4070 12GB | 1x1TB M.2.

GOAE Posted March 25, 2022 Posted March 25, 2022 (edited) You're unaware of translating tendency it sounds like. The aircraft will always push you right naturally because the anti-torque rotor is blowing air to the left. The main rotor is moving air mostly down but also in a counterclockwise swirl due to its circular motion, whereas the anti-torque is always blowing air to the left; since both are not entirely opposite forces they don't completely cancel out. The rotors are on different planes after all. Only the torque of the main rotor gets canceled out (when properly trimmed), the translation and lift are separate forces that are not canceled out.

While explanation is correct, TR is blowing to the left
