FMS FMM080P Owner's manual

Hello! I've read the FMS 980MM P-39 HELLS BELLS Operating Manual. This document contains information about a radio-controlled airplane with a 980mm wingspan, and 6-channel radio control. It uses a brushless outrunner motor and can achieve high speeds. I understand it provides assembly instructions, safety precautions, and spare parts lists. I'm ready to answer your questions!
What is the recommended battery for High Speed (HS) version?

What is the recommended center of gravity (CG)?

What is the motor rotation direction?

What should i do if the motor is rotating in the wrong direction?
