I am considering using the Catto prop with a parrallel valve 180hp.
I need to figure out how heavy the crush plate and extension needs to be to bring the C of G ahead.
Does anyone know the arm (distance) of the prop flange for a parrallel valve engine?
David,
You are fairly close to where I live. I have a -6 with the O-320/Sensenich combo and have a slightly unusual situtation (at least in my mind). I would like to ask where you trim tab is in normal cruise flight. Mine is "up" at almost the limit. W&B is 70.70" ewcg and 1166#. Flys alright but bugs me that the trim tab is so deflected. I talked to Scott at Vans and he said no problem, but looks very odd to me. Everyone else I talk to "says" there tab is neutral in flight, but most had electric trim with indicator so they really did not know. Just wondering if you know where your tab is in cruise.
