Yes that is a very cool video of the KI-43 on u tube. I've always thought that the zero was an ugly plane but that the Oscar was a very clean and sleek design. I've got a 1/72 Hasegawa model of one hanging in my basement.
In reguards to the airframe, the Hurricane would be far tougher than the
F4F or the p 40. There are several reasons for this.
The F4F, P40 and most WW II planes are of stressed skin construction, meaning that the skin of the aircraft is part of the load bearing structure of the aircraft. Any damage to the skin brings a resultant loss in the structural integrity of the airframe. These airframes are vunerable to machine guns ripping the skin or the overpressure from cannon shells rupturing the skin. The Hurricane is based on an older English method of construction. Although tubular steel airframes had been used since WW I, most of these used low quality mild steel that was welded together. This resulted in a heavy airframe that wasn't really that strong. Hawkers solution to the problem was to use lightweight high quality steel alloys held together with mechanical fastners.
This type of structure is very resistant to damage especially from over pressure but also from mg fire. It was also much more easily repaired. The wing is a two spar structure running clean through the fuselage. The spars are also made of steel , the two in the center section being made of heat treated spring steel using Hawkers welll known dumbell spar. The only stressed skin construction on the Hurricane was from the gun bays outward to the wing tips. Keep in mind the Hurricanes wings are also 18 inches thick at the gun bays adding to this immense strength. For its size the Hurricane is relatively light , the main drawback of this type of construction is that it leads to a bulkier less efficient airframe.
