Does anyone have a maintainence manual for the scorpion 133 helicopter. I have one thats ready for flight but would like a copy of the manual before i do. I have the 133 engine manual but would like one for the air frame. I need to know how often the belts, chains and bearings need checking and replacing. Also, how tight must the belts be. I keep getting told they must be tight. How "tight" is tight? If any one can help i would be greatful.
