Guizmo- set the AFRs as in the third paragraph above and you should be good to go.

Dave- yes, the Kasama is sized for 4-4.5mm grips, which means FG or CF blades. The Align 315/325 FGs work well for puttering around blades, and they're fairly cheap. All of the gray anodized aluminum parts on HD are the Sonix brand. Sadly, HD discontinued the DoD I believe.

Sorry about the crashes, folks. redvtr, it does sound like something malfunctioned in the head in flight. I had the pitch ranges set too high on mine and managed to bang the flybar levers against the grips (also doing flips, unsurprisingly). Mine didn't crash, but it sounds similar to what happened to yours.
