Dreiblatt (fixed) Printer JGAURORA-A5 Filament HK PETG Propeller Diameter 250mm Pitch 165mm Corresponds to 9.8x6.5 Motor shaft diameter 5mm Attachment of individual blades with a 2mm carbon rod and seconds adhesive. Attachment of the cap on the spinner with an M2 x 12mm socket screw. Weight 28.7g including screw. Performance testing on a test station running on ball bearings, resulting in minimal deviation of thrust measurement. Performance with 3s battery: 540g thrust 18 Amper 5000 RPM Performance with 4s battery: 650g thrust 23 Amper RPM not measured. Not yet tested in flight. Before the flight, I will, as always, coat my propellers with a very thin 2-component epoxy. From my experience, the propeller is not only smoother and more stable but also gains additional strength. Although at these low RPMs it's not necessary. The weight will increase by another 3g due to the coating. Have fun printing Hubert Lidlflieger https://www.youtube.com/watch?v=_pmWOvn3eN4
