I've mentioned this before, but my old 520 was truly a STOL plane. Full flaps, full power, it stalled at 39kts per POH. I kid you not. Took that to desert dirt strips, Johnson Creek etc. At home base at El Monte lined up on the chevrons, I could be off before the threshold about 600ft later. It was amazing in that regard, but that was all down to the geared engines - they had insane amounts of torque and you just can't get the same acceleration on direct drive engines.
