Compared to the old one, this version has a lot of internal changes

Weight, Lift and general performance

the old Raf-23 weight was just fuel, when you are low on fuel the fighter turned like a X-29 and the landing procedures were too complicate. this new version have a new weight balance starting from the clean fighter, then the weapons, and finally the fuel

Speed

this RAF-23 reachs better the speed that are designed, Mach 2.25 at 40000ft (1502kt) and 850kt at sea level, being a fast interceptor

Manuevability

as any heavy Interceptor is not too important the manuevability, dogfighting with other realistic fighters is ok, but compared with regular fighters in the website you feel it
