Nightmare to work on, engine is upside down and and faces backwards. Everything is hard to get to, manuals are ****, cowls and panels held together by self tapping screws.
Alignment of belts, pulleys and shafts are "fun" (especially oil cooler blower shaft as when the boot is loaded it changes alignment). The drive belt clearance sdb is wonderful especially when the plenum is manufactured with next to no clearance.
Topping up oil in the pulley is a job filled with lots of swear words and banging your head on sharp things, then to lock them up again with no room for any tools. Damper rod ends are a good spot for corrosion you cant see.
A well track/balanced machine flies great though and plenty of room in cockpit for 2 people.
