Funkie, C152 inverted - only gently downwards and quietly
. The amount of forward stick needed in the Grob/Firefly etc. is because the aerofoil is very inefficient when inverted (much higher AoA needed to generate same lift at a given speed). Stall speed is much higher too. All much easier in a Pitts or similar with symmetrical aerofoil.
Next time you're up, try working out which way to bank in order to turn in a particular direction. Great fun
.
