<DIV>There are several carbon fiber options for 3 blade props that we should consider at: <A href="http://www.desertaircraft.com">http://www.desertaircraft.com</A></DIV>
<DIV> </DIV>
<DIV>Here are the options:</DIV>
<DIV> </DIV>
<DIV>16x12 Air Models $74</DIV>
<DIV>16x13 Bolly $52</DIV>
<DIV>16.5x12 Bolly $52</DIV>
<DIV>16x11 Mejzlik $54</DIV>
<DIV>16.5 x14 Mejzlik $58</DIV>
<DIV> </DIV>
<DIV>The question is: Have someone tried this props for pattern? It would be interesting to find out which one of this props is equivalent to the one we are using now. I will call DA tomorrow to find out if they know something in regard applications in the engine we use.</DIV>

<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>

<DIV><FONT face=Arial size=2>This is just an FYI to those interested.</FONT></DIV>
