4th Gen Dual engine Mid/Light fighter with 3D Thrust Vectoring.
I would like to suggest a 4th Gen Mid/Light fighter with 3D thrust vectoring as a main feature with a size in-between the F/A-26B and F-45A with decent speed. To fully make use of 3D Thrust Vectoring the aircraft would have to have the engines set a good distance apart, so for inspiration I would like to suggest something along the lines of the MiG-29/Su-27 with engines set a good distance apart and room for underslung ordinance. (Note: This is not a request for a MiG-29/Su-27 just a source of inspiration.) We do already have an aircraft with similar engine placement in the EF-24G although it does not have TVC. Pulling from these planes for inspiration would satisfy the people that want RedFor playable planes. This could also lead to possible Equipment such as Infrared Search & Track (IRST) Which could be added to airframes with integrated TGP/EOTS ,although not required.
Ultimately I would like to see a Mid sized Fighter with 3D TVC as a main feature. This could be controlled by the Fly-By-Wire system and only turn on under a certain speed or alternately forced on by a Switch on the same panel with the G limit and flight assist. Performance wise I would like to see this plane have a Decent Top speed and Acceleration similar to but less than the F/A-26B, be able to Pull Around 12 Gs before damage. For example the F/A-26B can sustain 13Gs before taking airframe damage, and the T-55 can Sustain 11Gs before taking airframe damage, this would place it between the F/A-26B and T-55 performance wise filling the gap in playable planes. I would like this to be a good dogfighter but not the Flat out best as this would make it boring.
TLDR:
4th Gen Mid/Light Fighter Dual Engines
3D Thrust Vectoring as a main feature
12Gs Sustained before damage
Speed Slightly slower than F/A-26B
Minor focus on Close in Air to Air performance
