Probably my favourite quad to fly, totally locked in, feels super efficient with awesome endurance, very light on controls without being wobbly or too floaty (Supafly 7" preset with RPM filtering).
4s build with 7x5.7x3 props, 1500-2200mah 4s LiPo (470-500g AUW) and 1550kv Flyfish 2506 motors.
Greate alternative to TBS Source Aureo, same weight with much stiffer frame and significantly better aerodynamics.

While the complete quad only weighs 320g without battery, and frame is 64g including aero canopy, it's much stiffer then traditional 7" frames, which are easily ~3x the weight.
Flight times with ~1500mah 4s battery (470g AUW) are 10-15 minutes, with 2200mah 4s battery are 20-25min when cruising.
With 5000mah 4s Li-on pack (600g AUW) I expect to see ~45min endurance.
In the photos you can see arm deflection comparision (20kg load) between average 7" frame with 141g weight (so definitely on the lighter side for 7") and SpaceDrone, the differency is even more noticeable when trying to twist the frame, comparing torsional stiffness.
