So I recently bought a Wind Racer kit from Will at Tippecanoe boats, maker of the T37 rc racing sailboat.
These are a wind mobile, yard art.
I know this is not directly rc sail boat related, but hey, fun is fun. Here’s a short video of the one in my backyard. Easy assembly, you paint or varnish, then assemble.
Here’s a link to where to buy one should you want to: http://www.tippecanoeboats.com/windracer
