Main problem with this kit is unclear instruction. You better look on some photos while completing rotor hub. The instruction has very small drawings. Cockpit glass doesn't fit to fuselage so be prepared for few sessions with sandpaper. Also, You'll have to fill a lot of...I forgot english term...I'll try to describe: marks on parts after pushing sprue out of casting form. Some of them are placed on parts being difficult to sand f.ex. wheels. To make this short - good luck :)
