This is my second alternative model built out of set 31017. I've almost given up when I was trying to build it. I was not able to attach main rotor to body till I've found Frederic Bouchard's helicopter that showed me good way how to do it. If you wanna build it there are building instructions at buildinst.sweb.cz
Hi! Thank you for your comment. I looked what you built with this set. It's all very creative, especially the windshields in black, well thought out! Your helicopter is very aerodynamic. Mine is more square!
