I have to ask why you'd want a KI84 that can do 427 mph when it sheds parts just above 430 mph?


  Ya I know silly question.......

The 426 mph referenced by the OP is TRUE AIR SPEED.

Structural failures are based upon INDICATED AIRSPEED.

426 mph TAS at 23,000 feet is about 292 INDICATED AIR SPEED, very far away from breaking parts off.

 As you may notice I didnt mention IAS or TAS! Just take an 84 up to about 25k,then dive,watch E6B,then when above 430 TAS pull out of dive,then report your findings!

 I would have to test again to quote the actual figures but IIRC it's about .61 Mach and pulling out breaks both elevators!



  YMMV!

Seems there are many caveats to how AC performance is modeled in AH.  There doesn't seem to be a "standard." For example, some are modeled if HO fuel was available in the field, others not for balance reasons.

The D11's in the field were not equipped with Hamilton "paddle blade" props from the factory but were equipped at  airfields by representatives from Republic and by unit maintenance crews.  This prop gave the D11 a significant boost in climb rate. Of course, this has been discussed on this forum several times.  The fact remains, the Hamilton Standard prop is not modeled on the D11 in AH.
