I'm building a Bridi Big Bee for my Honda GX25. I must have gotten the last Big Bee from Sheldon's about 2 weeks ago, I tried to order another 3 days later, and they were out. Every single piece of wood in this kit was solid, Ribs, bulkheads, fuse sides, hatch, etc. I spent some time with a router and dremel cutting holes in everything. I've heard they fly real well even over 15 lbs, so I hope I'll have a floater, and the Honda won't be pulling it around like a G62.
