Hi All,

The P-880-3 is the new part number for the counterweighted blade MT  
Propeller on the narrow deck 540 engine.  It has a single control  lever.  The
six 
screws on the top of the unit are loosened to rotate the  arm into the desired

position, and then tightened again.

The P-440-15 unit has two arms.  The lower arm is the control stop  arm.  The 
upper arm is removable on a splined shaft, and can be positioned  where 
required.

Regards,
Jim Ayers

I received a P-880-3 governor for my 3  bladed MTV-9-B-C/C198-52
counterweighted propeller. Narrow deck. Hasn't  been started yet.

Hi All,

On the P-440-15 governor for the  counterweighted blade MT Propeller, I  
measured 2 1/4" of travel from  the factory.  Anyone get anything  different?

If you have the  narrow deck engine MT governor on a wide deck  engine the 
travel will  be greater, since the low pitch (high RPM) stop has to be
turned 
almost  totally back in the pitch stop block.

Jim Ayers

So the real question  is: what is the true  necessary throw for all controls
??  (This  is for us that build our  own control quadrants :-)
Can someone  provide the linear control throw  for:
Throttle
Propeller  pitch
Mixture
thanks !!
