Hey Bill-

Sorry to learn about the woes you are experiencing with the rebuild. You know you don't want to sell your BABY (airplane baby that is)! Yes it all is
quite daunting, especially with the problems you have had but keep your chin up and just plod along day by day. Things have a way of working out. They just take longer than we would like sometimes. Hang in there. Hope 2010
will be a great year for you and your family!

To be clear, Whirlwind Propellers makes the prop hub sized for 7/16" bolts. My O-360 will have 1/2" bolts. I knew this going in and worked with American Propeller, Whirlwind, and Sam @ Saber to make sure the prop I was ordering would be machined for 1/2" bolts. So, when it arrived with the smaller holes I was disappointed.

Whirlwind's plan was to have Saber make hubs that reduce the bolt size from the 1/2" on my O-360 hub to the 7/16" bolts for the prop. A few months back when this came up I refused to go this route and was told they would make the hubs sized for the 1/2" bolt. Hearing that, I placed my prop order and ordered a prop extension with 1/2" bolts from Saber.

My feeling is that there must be a reason Lycoming increased the bolt size. Even though Whirlwind insists the 7/16" bolts are fine up to 200 hp I am not comfortable doing that. Increasing bolt size is one thing but reducing them is another thing entirely.

Today being New Year's Eve, it was difficult getting everyone on the phone to resolve this.

As it stands, unless Whirlwind wants to make a new hub sized for 1/2" bolts and can get it to me within a month, this is going back. Also going back is the prop extension as there is a difference between extensions intended for wood and metal props. (Sam is great to deal with and will change out the extension for me. Thanks Sam!)

I spoke with Craig Catto today and he can whip out a two bladed prop fairly quickly.

In short, if your engine has 1/2” bolts I cannot recommend the Whirlwind Ground Adjustable Propeller. If you have 7/16” bolts it looks like it might be a good propeller option. Note, I have not flown with this prop, nor have I been able to mount it on my engine.

PS. This prop is "sized" for 150 to 200 hp engines so it is not like I'm trying to make it work with my O-360.

Default One Word Bill

Hartzell. Unless you have a solid crank then Sensenich. I beat Mike Thompson in a race last year because he had to slow down and deviate around light rain on course with his Catto.

I keep telling him that!

Besides, why stop now? The 9 is upgraded to an oversized engine, and might as well go all out with the sensation of power, and the ability to do things unknown to the fixed pitchers. His plane will be a "wimp" no more....

No thanks. Adding a blue knob requires replacing my throttle quadrant which would require remaking the switch sub panels to make room for the wider TQ.

That and I don't want the weight or complexity of a CS prop. If I did, it would be the 200RV from Whirlwind, the other Whirlwind.

If I go with Catto, I'll just have him install the leading edge tape so rain won't be an issue.

One other thing, NO WAY am I going to install a CS prop now. I can just imagine the posts LA would be making about me going completely over to the dark side.

Good news today. I just got word that my ECi engine kit should ship tomorrow. That's just a little less than three months from when I ordered it.

The engine mount and gear leg are boxed up and ready to go back.
The Whirl Wind prop and spinner are boxed and ready to go back.
The Saber prop extension is boxed and ready to go back.

I'll order a Catto prop & spinner, a different Saber extension for wood props, assemble the engine, and hope Van's can turn around the engine mount quickly.
