Decent blades, although shipping is a little high. Nice performance in four and five blade rigid heads in my 450's.

Weights are very close matched.

this will be a great match to the scale rotor head. hope it has sufficient rigidity and not flex too much

These blades are excellent for those who want to use main rotor scale with more than two helicopter blades with flybar system, without needing to use 3G equipment Flybar-less.

I use these blades with the HK 450 4-blade Rotorhead. The only issue is that the root of the blades are too thick, caused a severe vibration on the first test run, which destroyed my three cycling servos (although MG servos :-( ). After i sanded the root of the blades, as described in a review here, and changing my servos and the main rotor shaft, the helicopter is running perfectly smooth. Nevertheless i give 4 Stars, as the blades are almost perfect for this price. But DONT FORGET TO SAND THE ROOT, that cost me a lot of money...

I purchased six. They all weigh exactly the same. They are flexible, yet stiff enough for multirotor flight. They have molded in lamination details at the root and realistic looking "trim tabs" near the tips. They are perfect for my A109 project.
