Davis DA-11

[Eric Witherspoon]

I've been looking for an article on the Davis DA-11 "Mower Power to the People". I found the DA-9 article in the August 1996 issue, so I believe the DA-11 article would have been after that. I thought the DA-11 was on the cover. Now I'm thinking it was one of the Experimenter magazines when that was printed as a separate publication. Anyone have this, and could scan or photo it for me?

Along that line - will EAA be scanning the older printed Experimenters as part of the searchable online archive?

Just did a quick google search for it and the one page article popped up at AirplaneZone.com. Hope that helps.

There was just the one page only in Sport Aviation. Contact magazine did a full article, and I think it was reprinted in the alternative engine book series.

Got it. Thanks!

I would love to find plans for the DA-11, but my research suggests plans were never sold. What similar all-metal, high speed (90+ kt), low operating cost single seaters would be comparable to the DA-11?

The DA-5A. Plans were not available for quite a while, but are now available again see davisda2.com. I have a set. Some of the pages show 100% size parts, but the duplication process makes them slightly off, so would need to check dimensions and rescale the copies. The brake attachment at the landing gear isn't defined, but I asked on the forum on that site, and they provided the equivalent drawing from the DA-2A.

If you read the article that I was asking about, there's a significant issue - Davis couldn't kit it way back then because no lawnmower company wants their engines used in airplanes. Also check max pilot weight - might be lower than you need.

The DA-5A can handle a pilot up to about 205 lb.

Another option with lots of current builders, completed / project airplanes for sale, and an ongoing source of parts & support is the Onex by Sonex.
