Here is a new plane, with Delta wings!
Moreover, i gave you 3 presets, one already on the plane, and 2 others next to him if you want!

It can go to 1688kph(Mach˜1.42).
It can fight other fighters even if he's armed.
It turns well and accelerate fast.
It has 2 flares lunchers and 1 chaff luncher.

Try it and see how far you can go with it :}
()(P.S.:It took me a half day to do it and perfection it, more version to come maybe.)()

Here is the A-1B version, highly improved in maneuvrability, rotate more calmy, but still with speed, and can turns better or with less energy losses by the trim position! Enjoy.
