I just need a little help getting this thing the fly, it's a little different than simpleplanes physics. I think it's probably from a lack of thrust.

You are probably right. It has a huge cockpit that may be blocking the inlets. @kansaspilot

@Planeacceleration the main issue is that the inlets aren't getting any air, due to the size of the cockpit, and the position, and size of the inlets.
My advice for how to fix the design would be to remove the inlets on the side, and put a large scoop style inlet on the bottom (look at the F-16 for an example).
additionally the twin tails may be a little too close to each other to work in that position, to fix this you could either tilt them (like on an F-18), or space them out a little.

Honestly after trying to fix it for you, i think the whole design may be flawed.

Thanks, that would be awesome if you could post and Tag me to it. Yeah I wasn't sure how to make flaps because there was no VTOL bar or Activation Groups. -

Oh, one other thing I though needed a tweak: the default deflection angle of 35 degrees makes for a very sensitive roll. So for a nimble fight like this you can turn that down. (I set the roll controls to 10, pitch to 20, and flaps to 30). Let me know if you want I can upload my tweaked version.

The number one issue here is the amount of air making it into the inlets. Your engines are rated to produce >500 kN but they were only putting out ~85 kN. The thing is SimpleRockets2 doesn't seem to do a good job of letting air flow around things and into inlets. If you look at your plane from head on the canopy occludes a lot of the inlet area. By tweaking the inlet and canopy shapes I was able to get actual takeoff thrust to be over 300 kN which should be plenty for a 22 kg plane.
Even with lots of thrust the plane still was being slow to rotate and takeoff. I'm no expert with the plane design by a threw a smattering of tweaks in:
- Moved the rear landing gear forward to make the pivot point closer to the COM
- Lengthened the forward landing gear to give the plane a very slightly upward pitch
- Added another set of control surfaces to the wings to act as flaps and bound them to Slider 1 with the left side inverted.
With these tweaks I was able to rotate and take off at 110 kts with runway to spare (instead of 150 kts very close to the end of the runway).
