Could it be Ross Walton's Tripe? It was for sale a while back and I think I read somewhere that it was being switched to a rotary.
Here, I found this info on another forum.
"Some time around the new year I stumbled across a web page about a Fokker Triplane replica in the States which stated that the machine was due to be auctioned sometime in May.
The machine in question is a replica of
Werner Voss' pre-production Fokker F.1 103/17, complete with all the F.1 features (eg. convex tailplane leading edges) and powered by an original rotary engine. As such ,it seems to be something a bit special compared to your 'average' Triplane replica.
I'd not heard of this machine before, and having googled like mad and hunted high and low for any info on this machine I can't find that page again and there doesn't appear to be any other info about it available anywhere.
Can anyone reassure me that this machine actually does exist and that I'm not losing my marbles?:confused:

Here's another, perhaps from this forum's Baldeagle-

Ant, the Triplane you refer to is the one in my photo in post #24 with the black-and-white striped horizontal tail (later changed to Voss' colors), 3rd from left. It was owned by Ross Walton in Kentucky, and has since been sold to Javier Arango in California. The web site belonged to Ross,
Vintage Aero Fabrics, distributor of aviation fabrics , and the listing for the Triplane has been removed since it was sold."
