Actually, I've built several sizes and makes of it, it's a hard core flyer, the larger you make it the better. The plans are simple, make a ring, make the front end heavier then the rear, you have a geobat. I did a 16" FOAMie of it, I broke it up into 4 sections, it's glide ratio is incredible, there wasn't even a need to add weight, I'll be building another soon to be a trainer, it's just that easy to fly.........
Ragged views of the original, 170 crashes into the walls and keeps on flying, hehe.
