mechanic Posted March 9, 2010 Report Share Posted March 9, 2010 Hey, I read this on Vertical Online. A few other notable news bits at RHC include the return to aluminum main rotor blades. The R66 has them now and the R44 will soon, followed by the R22. Anyone operating a current model need not worry, as this will not impact the use of the stainless steel blades now in service. What is the main difference in the alum vs. stainless blades?? Just the material or structure of the design? Thanks Quote Link to comment Share on other sites More sharing options...
