features
- carbon composite blades
- nickel leading edges
order number
- 330-3B-A/78G-78-S-R (before slash is hub model, after slash is blade model)
- Hub
- 330 = hub series
- 3B = number of blades
- A = SAE-2 1/2" flange
B = SAE-2 7/16" flange
- Blade
- 78G = Blade Style
- diameter
- S = Standard operation (increase pressure to increase pitch, goes to flat pitch on oil pressure loss)
C = Counter-Weight (feathers on oil pressure loss) - R = right hand turn (clockwise as seen from pilot)
L = left hand turn
- Hub
