Helix vs Eprops 140 cm - Thor 202/303 the Helix is a Sloppy Mess

The Helix measures at 25.5 mm with the hub at 25.0 mm. That's 0.5 mm of slop with a propeller that weighs 400% more, that could be described as "not good", maybe more like "mediocre". I have three Top 80 props (eprop, wooden, chinese), all have minimal or no slop.
