Hey whizz what kind of aeroplane do you have in mind?
The spectrum is so broad that your question is impossible to answer....everything from gb's 172 to my Bonanza.
In fact those two probably neatly bookend the 'lighty' spectrum.
I didn't mean my post to put you off...far from it in fact...just to give you an idea where to start looking for the answers you seem to want.
BTW gb I completely agree with you...nice to see someone who appreciates the classics
