Great looking canopy that comes stock with your 450x! I love the color scheme on this and it does the job acting as a canopy on your 450x. Anyone who has any Blade heli know the canopies are fairly thin and usually will crack during a crash so just be carefull with it. The seam on the bottom could be glued a little bit better so I usually just apply some extra glue before I fly it to ensure is stays connected. 4/5 for me just because of how fragile all Blade canopies are.
