Package contains: 4 pcs of blade no. 8501, diameter: 13,0" Pitch range: 15-21". For propeller models 8901 & 8902
Blade kit 8512
The blades are from spring 2013 made of a new stronger and stiffer material colored grey. That´s why the bladekit has changed p/n to 8512 (8511 obsolete being replaced by 8512 ). The new blades are compatible with older propellers, but should not be mixed with the older black one's other than in emergency cases.
