SPAD XIII = full operational weight: 820 kg
Hawker Hurricane Mk. IIB = full operational weight: 3740 kg
I chose the Hurricane, because it's tail was partially wood and canvas.
Actually, the aft was aluminum tubing with fabric covering on the Hurricane. The early models only used sheet aluminum on the forward fuselage. Later it was used on the forward fuselage, wings, and the fin, and stabilizers, with fabric covering the fuselage aft of the cockpit, and the control surfaces.
One thing too, about WWI arms, is the way guns jammed. Guns mounted away from the pilot were dead with one jam. With them mounted in front of the pilot, if a jam occurred, the pilot had a chance to clear the jam. In WWII planes, with wing mounted guns, once jammed, they were jammed. The early 4 gunned P-51 sufferred from this problem. Plus the guns have to be charged before firing, and then in the cold skies over Europe, how do you keep the guns from freezing? Especially in the cooler times of the year.
Wing construction too was a big issue. As was powerplants for aviation. Most of those old aero engines didn't use ringed pistons. They used pistons that had oilgrooves for lubrication, which effects the power output. Also, the size of the pistons were huge for the horsepower they developed. Pison rings allow for higher compression, but with higher compression, now you need a higher octane fuel, or the engine will knock itself apart over time. Like the P-38 the Italians captured. They insisted on flying it regularly, but because they used a lower octance avgas, compared to the Americans, and the British, the engines didn't last long.
There is a lot of other factors too, but I need to go and finish planting corn and beans out in the back acre.
