Interesting, congratulations! Links to gizmo's site, ecoinnovation (kiwi) and burmeister's site will enhance yours.
There is some overprinting of text on the balancing prop page.
Interesting disk brake setup. I will have to see a shop in Perth and ask if fittings are available to attach guy wires to mast pipes or if one always has to weld one.
Your welding is better than my "multi-point tacking"! I believe the cheap 120 A welders set off the thermal overload frequently causing the arc to disappear.
