Have not flown the T-38, but the F-5 A/B for 7 years and I found the model is pretty good. Even the final turn is, IMO, well simulated...the plane looses speed very quickly during a steep final turn and set up a dangerous high sink rate...so don't drop the nose!
Maybe a tip: make sure the nozzles are at minimum in full Mil (not in afterburner range) if you have a throttle with an afterburner setting....Otherwise you will not have the needed full mil power during a steep final turn.
Have fun!
