Important Event Report!!!

[White, Chris]

Thanks Bob for putting out that report.  I sure hated to hear that,
cause as you know the 3-blade is sure impressive on the 160/Arresti IV
combo!!

Today, while running an OS 1.60 with Master Airscrew three-blade 16 x 10
on the ground, ONE blade departed cleanly at the hub at near full power.
The blade travelled approx. 45 yards, directly in line with the prop
disc-plane of the engine.  There were no injuries.

 

This particular MA nylon prop had approximately 75 flights with the OS
1.60 on Aeroslave pipe setup.  Ground peak rpm was in the 85-8600 rpm
range.

 

Based on other reports of three blade failures on the OS 1.60, I won't
encourage their use any longer.  Two brands, several different owners,
different setups.  Common elements - OS 1.60 on pipe and three blade
setup.

 

This is just an FYI to those interested.
