Blade 130x BO-105. Test flown a few times and then sat in my basement in a box for a few years. The blades have some staining but the model works fine and I will include a set of new blades unopened.
It's durable, EXCEPT for the tail and kick-up gears, those are delicate. Need to get metal gears for this heli. Not a 3D machine, too underpowered for that, but is still a fun flyer.
