Interesting new fact I discovered on the site concerned the Italian Folgore MC.202 fighter. Its left wing was over 8" longer than its right to counteract the engine's torque. Did any other aeroplanes adopt this approach?
Well, from the powerplant side istr that the Benz engine in the BF109, being an inverted design suffered from excessive oil intrusion into one bank of cylinders due to the way the crank slung the oil around in the crankcase and this affected the mixture and smooth running of the engine. The solution was to change the compression ratio in one bank so as to redress the balance!
I'd love to know is this bizarre solution is in fact true and not a myth. I rather hope it is, it's just too clever not to be true!
