History

In 2008, the SVAF were requesting a new combat jet capable of large weapon capacity, powerful avionics and EW suite, semi-stealth and supercruise, as well as supermanuverability, to replace the aging Su-35SM and to streamline the airforce's inventory, resulting in reduced operating costs and logistical burden. The contract was awarded to the RAE, which now is renamed to RDS (Relheon Defense Systems) and they developed a plane that would go on to form the backbone of SVAF multirole strike capability.

AG2 = Turn on lights
AG3 = Drop the AHSSM
Trim = Trim
Throttle beyond 90% = Afterburners

User guide and issues

The plane may flatspin when PSMing below 400kmh while also being sideways.

The plane may shake if you try to pitch when the afterburners is on, caused by the FBW over-correction.

The plane's speed, manuverability, and stability may degrade when in high altitude.
