Google, I just cut a basic float shape from blue styrofoam. It's kinda rough but it was just a proof of concept. Struts are toothpicks. I did find that they might be just a hair too small as at full throttle it almost submerges the front. Surface tension and the inability to hydroplane (lacks the power) keeps it firmly nailed to the water. Have to play with the adtl. wing & maybe a different shape float.

Micro - Take 94 to St. Cloud, then south on hwy23 for 35 miles and you're at my back door! Swing by and we'll fly sometime.
