My S2 Max serves as the backyard basher of my fleet and has lived a hard life (as did the original S2 I had before it). While I feel that the Max improved on the original S2 in pretty much every way, I found the plastic frame to be extremely fragile and unforgiving in rough landings. I have replaced several of these plastic frames while everything else on the heli survives fine (I've replaced a few feathering shafts and blade grips but thats it). So I was excited when they offered this CF frame because not only does it look better than plastic but it HAS to be a little more durable doesn't it??? Install was super easy and quick. I haven't crashed it with the CF frame yet but I have high hopes for a little better durability.
