Curious what's its ROD in autos at 80 Kts ?
300c (3 blades )is about 1800 ft min
500HS(4 blades )is about 2000
500D/E ( 5 blades )about 2300
So would assume that with 6 blades must be getting close to 2600 ???
Not a great comparison I know as 300 blades are about 4 inches longer than c d or e model ones about the same length as 600 ones
