I spent two days in HKG last week which allowed me to go to my stainless steel and tool shop. The blokes from the factory told me that I would need a 13mm and 14mm "crowfoot" for the propeller and engine mount as a normal socket will not fit the torque wrench. I also got a 14mm allen key, for the nose wheel bolt and a 38mm socket for the main gear wheel nuts. I also purchased some 3mm 4mm and 5mm button heads screws and washers.
