Webra 1.45 Prop

[David Flynt]

I have a ground clearance problem also but with a Webra 160.  Would this engine (mc carb) spin a 15x12 4 blade?

Thanks,

David

  You might be surprised how well the APC 16x13 works - very good vertical and braking for the relatively high pitch - and yes, it will go fast with the hammer down.  The 15x11 4 blade is also possible - but probably a little light on load.

    With the ground clearance problem, you are probably need a 3 or 4  blade. Bob Pastorello is an expert.

    Otherwise, the 1.45 wants to turn a 17x10 or 17x12.  Any less diameter, and you would need the pitch so high, it would make the airplane too fast.

      Need advice on prop for the 1.45 Webra.  I have a definite ground clearance concern.  A 17" just barely clears in a level attitude.  TIA for any help.
