these blades have great performance have bought these before and will buy againRoot thickness where the blade grips are installed is 5.63mm, measured with calipers. Does not fit Trex 450L.It's been a while since i bought this blades but i just realized that HK should commit to their custommers and at least offer an apologyze for this defective useless item.
Mine were thicker and dont even fit in the blade grip. Couldn't even bolt them to the heli wich btw its an align 450L dominator 6S. Bolt hole did't even had a brass tube inserted. Finish is horrible!! Really guys, i'm not a delicated nor fanatic guy, but this is a complete lack of finish.
Why i give 1 star on value?!?!?! Because even when they are ectremely cheap, i coudn't even bolt them!! Any price paid justifies a useless item.
I really expect from HK at least an apologyze and remove this item so no one can buy this item again.Don't buy those blades. HK shouldn't sell them.
I have 4 pairs. All of the useless.
Really awful product.
