I put together a historical recollection of my Kitfox build and development for those that are interested.

Nicely done !

You have some great outdoor pictures!
I really liked the close up shots of the panel as well.
Congrats on completing a really nice plane !

Great website. Photos, videos and awesome scenery, the whole works.

Now to get the Skywagons Only Club to recognize the performance of the Kitfox…

Awesome looking KF!
290D powered? Sweet!
Pretty good match-up with a Skywagon for a 2-ship fleet.

Scrolling down your webpage, I saw your old prop spacer without drive lugs.
My old C150/150 used a Sensenich prop with a spacer which looked very similar. You'll notice that there's an extra pair of holes in your old spacer, my Sensenich spacer had a set of dowels in those holes which matched up with a set of extra holes in the prop. The prop and spacer were a press fit, generally the Sensenich prop is sold with the spacer factory installed. Mine was p/n 74DM6-S5-54, the "S5" indicated a 1-1/4" spacer. FWIW I still have the S5 spacer if anyone needs one.

Love it, thanks for taking the time to post this. It's great inspiration.

Here's a coulpe pics of my old Sensenich spacer.
It's a press fit onto the prop via the two dowels which fit into a pair of extra holes in the prop, then the spacer/prop combo goes onto the crank flange engaging the drive studs, & the prop bolts go through the whole works.
FWIW I think the Saber spacer in your website pics is a better deal, with it's own set of six drive lugs.

Been thinking more about your Kitfox.
Looks like a great airplane. Like I said before, something like this would be a great stablemate to a C180, or a great replacement should a guy want to downsize a little.
I'm curious as to the empty and gross weight?
Also curious if you had to take any extraordinary measures (such as aft ballast) to keep the CG under control with that Lycoming 290 on the nose?

The Kitfox is designed for the bigger engines like the O-235, IO-240, so the O-290 doesn't weigh anymore than those setups. It is recommended to sweep the wings forward 1 degree to help with the CG. The airframe handles the engine very nicely. It is a real economical airplane. The empty weight and gross weight are almost exactly like the carbon cub. 440lbs useful for ELSA, 670 lbs useful for Amateur built.
