Look like nice blades. The Poles have been doing good work for years and have come up with a lot of good Aviation stuff. Something to keep an eye on. Bet the Shipping would almost double the cost.
That site is not working for me at all, just a blank page.
Website is back up and running.

I am ready to purchase new blades but am hesitant to import an unknown product....

Which profiles are those , Chuck? I am getting pricing done at the moment on a new blade extrusion in 8H12 .....but if there is a better profile I would be keen to see it. Also , what grade aluminium is recommended.If those blades broke at 300kn (67,000 lbs) in a pull test, it goes without saying that the resin is properly cured.
The thing that puzzles me is why they should select a failed 1940s helicopter airfoil (NACA 8H12) that Bensen picked for ease of hand starting. There are a number of modern rotorcraft airfoils that offer better lift/drag ratios.
Have they got any pics/details on their hub bars? Would like to know if they fit straight into our rotorheads.Yep
Almost convinced now to ship a set over to oz to try.....
