Thats true but there's nothing stopping us from making a GP airframe smaller.......just like by necessity the EP airframes evolved into the fragile painted eggshell that we have today !!!!!

Those bloated goldfish are the mutant offspring of F3P planes that escaped into the wild from their aquarium.
However, it's a bit like animals bred for show or anorexic fashion models, as long as the schedules/judges keeps encouraging and rewarding the trend then it will flourish..
It'd take a brave person to turn up at a WC smaller model so they can run a heavier IC engine.
You'd need somebody with more courage than the bloke who showed up at the WC with an electric triplane.
