Hey all,
I just wanted to query a thing I've found with the Viper at Low altitude (at or below 300ft, although in the vid it happens up to 2500ft), and at high speeds (650-700)<. I have found that in these conditions, the Viper initiates a wobble, similar to an Underdamped door which increases in severity as it continues, in straight and level flight, during acceleration, deceleration or sustained speed (it always ends in decel as the viper strays left and right as seen below). It looks as if the rudder is attempting to correct a minor oscillation but underdamps and starts oscillating around the velocity vector. This behaviour can be seen below. This was performed at between 2/3 fuel and under.
Would this be considered normal behavior for the Viper IRL? The I have not noticed this in any other aircraft, and I am wondering whether this is an anomaly in the FCS or an actual noted real world problem with the aircraft. It has been noted by various other sources that the Viper can fly in autopilot under these conditions with the LANTIRN pod, which makes me think that this may be an anomaly within the DCS FCS coding? Would much appreciate clarification.
I noticed this while using terrain masking while out for CAP, and as such when I took out the airframe for some envelope pushing and familiarisation, I recorded the above footage.
Cheers,
Charlie.
