Just wanted to drop a note from Indiana, USA to thank all the contributors to this site. Middle of winter here, snow on the ground, more falling at this moment. Have had an absolute blast with landyacht constructed with ideas presented on this site. I would classify mine as a class 5 I suppose. (8'6" x 5'8" with 6m? sailboat sail, steel frame construction, stayed mast). Friend built a mini (dimensions?, windsurfer sail 4-5m?, entirely wood frame, 20" bicycle wheels and 3 forks). We cannot get over how close racing has been. About dead even most days if the wind is blowing (15-20mph). Still trying to figure out tuning my sail. Will post pictures and video, have to figure out how and shoot in a lower resolution I think. (pictures are blurry present res) There's nothing quite like a powerslide when a gust hits on a layer of snow and ice! Destroyed a pair of wheel barrow tires in two hours last Monday sliding around.
Difficult in this area to come up with windsurfer parts, but next build will be LLmini with 2 inch drill tube and wood composite rear axle. Feel that stored energy return from gusts will really help acceleration.
Curious to know how Clemcos rubber tire steering head worked out. Looked simple and promising.
Once again thanks and have a good day.
