True enough. True enough. We overdo things a lot in the US of A.

Look at the Sig Kadet Senior. 80" wingspan with a .40 size engine. That's a design that would have fit in during the 1970's. Most 80" models I now see at my IMAA club have 40 to 50cc gas engines or 1.2 to 1.60 glow. I remember .40 being a "large" engine and a lot of .074 and .15 size models that we now would slap .46 size engines on. We also fly models a LOT harder than I remember seeing as a kid/teenager. I flew mine like they were eggshells - and stick and tissue isn't much less fragile. We're suffering a bit for the weight penalty of iron-on coverings and solid fuselages.

Bigger servos and heavier linkages need bigger engines which add weight and require bigger servos and heavier linkages which add weight and . . .

A vicious circle.
