I'm New Here
Hello All,
Hoping someone can help with a prop question.
RV7A with a XIO-360-A1A has a Hoffman C/S composite prop with a PCU5000X governor.
On runup the prop cycles appropriately,
However in level flight can only get prop to decrease to 2500 despite any further pulling of the prop cable.
As I ascend, the prop speed then decreases to 2300, and when I head down, it speeds up back to 2600 even with small attitude changes.
Cant seem to keep it constant with small changes in attitude.
Sent in Governor and its bench tested fine. stops are in place where should be.
Prop was recently overhauled and has less than 50 hrs.
engine running fine otherwise. no leak or oil on prop.
The front of the Hoffman has some sort of pressure relief valve that I'm not familiar with however, wondering if this needs an adjustment?
Also when the plane is sitting, I can very easily move the blades through their fine-coarse pitch range by twisting them.
Sent messages to Hoffman, however they keep sending to more and more technicians trying to figure it out.
anyone familiar with Hoffman props could offer some insight??
Jon
