Twitchy AircraftTypes

I've recently made a video, and there the large Allied and Soviet planes (Yuri planes are affected too) can be seen "twitching" at times for some reason.

The planes were made by MigEater, chk them here: https://forums.revora.net/topic/55382-props-to-ya/

Footage (twitchy planes start appearing at 2:37 and it keeps happening to planes that have fired their Primary= at least once, doesn't end until AircraftType de-spawns):

This is caused by a combination of the animated HVA & the banking/rolling effect that planes have when turning. To fix it add PitchSpeed=1 to the aircraft, this will disable the banking/rolling & stop the twitching.

I presume that the aircraft roll is normally calculated from the aircraft's current location to it's new move point in a curve etc. With the addition of the HVA animation though it's instead calculated every frame, so when flying at some angles the aircraft switches between flying straight, then turning/rolling & then back to straight etc with each frame making it "twitch".

Fixed. To make it more realistic, ROT of the planes reduced to 1.
It looks good now.

A similar bug is present in TS too. Sometimes AI-controlled aircraft fly to the edge of the map and continuously re-calculate a landing spot, causing a twitchy motion.
