Bug: SU-25 Force-Feedback Airbrake

[Khangirey]

Tested with the VPForce Rhino FFB.

The SU-25 is one of the few aircraft that have a specific force feedback effect on the engagement of the airbrake. When the airbrake deploys, the stick will mechanically "click" back and forth in a rhythmic fashion. This makes flying with the airbrake out very annoying. I was hoping that the developers could remove airbrake FFB effects in the meantime until a more proper fix is deployed. Many other aircraft don't have any effect at all for the brake, so this wouldn't be removing something that will be missed.

I wonder if that's related to the "su-25 view shakes whenever airbrakes are out" bug...?

[AeriaGloria]

Does this happen at any speed or only above Mach 0.62-0.7? 

[Ironhand]

Su-25 Clean, No shaking beyond high speed shake at around TAS 900 k/hr, M 0.76.

Su-25 Dirty, Shakes right down to TAS 360 km/hr (probably further but that's where I stopped) (TRK of this attached)

This is amateur guesswork, but isn't it possible that this is the same function as the stick shaker, to let the pilot know that the airbrakes are deploying?　I am a fidgety person and sometimes forget to close the airbrakes.

The Su-25, which descends rapidly with the airbrakes deployed when dropping unguided bombs, will have these on the wingtips that do not deviate from the aircraft's center of gravity to avoid deflecting its path due to brake deployment The Su-25 appears to be a very particular aircraft design in this regard.

The FSX F-18C was interesting in that the deployment of the airbrakes raises the nose of the plane so that the back is pulled backward.

I really like the centerless SWFFB2, as it allows for easy, subtle aircraft control and gives the illusion of improved formation flying.

Personally - I use an MSSWFF2 too, and find the airbrake shaker a very useful reminder the air brakes are extended.
