I have experienced a bit of the reverse situation! I must have had good instruction, because I repeatedly tried to consult the POH, of my newly (but not new) bought plane only to find it offered no answers. For one example, I searched in vain for a schematic of the electrics, so in the end I had to concoct my own - luckily helped by a fellow flying the exact same type. Also, the one thing approaching a POH published by the manufacturer only covered the tailwheel version, and of course I have the three-wheel variant.
@above: I had to look twice at the "rods, poles and perches" bit - then laughed my head off!
