Buyer beware this is a cheap crappy model! The plastic is VERY brittle and oily. Part of the propeller pin broke while trying to squeeze it in place so then I decided to pin it with a piece of paperclip and the part of the rotor housing broke while I was carving out the hole with my Xacto. This is from Michael’s and only my second Revell modell. I am now very leery of all their stuff.
