Foaminator,
I have 2 GWS Zeros. The first one turned out too heavy and I didn't have a good pack. The latest one flies much like yours.

Awesome! I love your video. I will post some detailed mods. and a pic soon. 8 cell HE Cell 700 NiMH, 3 HS-55's, Pixie 14 ESC, 13.25 oz. RTF, 8 minutes flight similar to yours(chasing seagulls, flying inverted, loops, rolls, etc.) Like you, it's my favorite plane. What do you think about a folding prop if taking the gear off to avoid breaking a prop or bending a shaft?
My next project is a HiPo GWS A-10.
Doug
