I don't understand why you guys keep saying weight = thrust.
Weight=mass*g
-> mass directly proportional to weight and g is constant
greater mass/weight in free fall gives you more inertia to overcome drag forces. Inertia is not thrust. p-47 was big plane with big torque radial engine (not the best drag profile to slip through the air). So it was a trade. A big engine to drive a big prop of a big plane with big drag profile. If p 47 want more acceleration off the line, simply take a steeper dive angle than fw 190 and fill up the tank with fuel and load up on bombs. So, inertia is not constant either. It depends on the loadout and dive angle.
