Sounds like you did a good job. Dont mess with success! After you fly for a while at various flight conditions if you want to change it you always can, say at the next CI.

Default About the white Delrin pitch cylinder

"Of course, you can always use a protractor if you want and not use the pitch cylinder."

This may be obvious, but it wasn't to me and I did not see it in print anywhere: if you do decide, as I did, to use the suggested replacement hub (D-1?) and do not replace the white Delrin cylinder (which I did not) you have to make sure that the blades are seated as far out as possible when you tighten the new hub. I failed to do so and was surprised when my spinner would no longer fit. It acted as if the blades had become fatter, which led to me wondering if they were being pulled in further and presenting a wider part of the prop to the spinner.

I contacted Sensenich and quickly received an answer: I could put the cylinder back in to ensure proper blade positioning, or make sure that the blades are as far out as possible.

I'm putting the cylinder back in. YMMV.

The Sensenich engineer assured me that the D1 cover was much stronger than the original and was more than adequate to the task. I guess we'll see if that proves true.

It is my understanding that the three-hole hub cover is an optional alternative offered by Sensenich but its availability may be delayed by production issues. The use of a three-hole cover on an older one-big-hole cover means that you lose the auto-adjustment capability (not a big deal in my view) or you have to send the whole prop back to Sensenich for a pitch-adjuster mod. Lots of info on this in previous posts. Also, read Sensenich's FAQ and SB.

The FAQ (http://www.sensenich.com/wp-content/...16-06-revB.pdf) provides great information. Am I correct in thinking that Sensenich will sell us just the front cover half ‘E’ or ‘F’? If so what’s the cost?

I ordered only front half of Rev “F” Hub Cover with mounting bolts and hardware in July, 2018 for $195. Sensenich says this is discount price but I think they would have provided it for free based on severity of the SB...

Scott,
This is a link to a post (post 119) from Sensenich about this in another thread.
