RE: 56' razor yak
Just started flying my new Razor-Yak this week. Equipped with OS-91, digital Hitec servos, Futaba 2.4 Ghz radio. Wow! It really flies well. I am doing 3-D stuff that other my planes never could. I started flying with CG at 8", first flights with battery up near engine. Moved battery back into wing today and CG now at 8.5". Now I am kicking myself for not getting this one done sooner. It does harriers in low rates. waterfall loops need high rates for elevator. I'm still learning this 3-D stuff, but this slab can do any of the tricks, it is just pilot limited, for now.
