Eclipson Fly Baby - Maiden Flight

I was privileged to print, build, and fly the Eclipson Fly Baby during their beta test program! The plane printed very easily due to its vase-mode ("spiralize outer contour" in Cura) design. Most testers printed in LW-PLA, but I printed mine in Polymaker PLA Pro (green, red), Voxel PLA+ (yellow, white), and black Overture TPU for the tires.

Assembly was very straightforward and much like other Eclipson designs. The unique thing about this model is the lack of a monolithic spar; it instead utilizes fishing line anchored in the cockpit and on the landing gear to stabilize the wing. I was actually very surprised at how strong the wings felt. I think the fact that the anchor points being located halfway between the wingtip and the fuselage actually lends extra rigidity, limiting the distance between sections of the wing that are unsupported.

I also utilized the AMS unit on my new Bambu P1S to print the rudder in red/white stripes. I had to split (in the slicer) the top piece of the vertical stabilizer and print them separately (one green and then one red/white striped), but it came out looking great.

Due to my choice of filament, I needed a lot of extra weight up front to achieve CG, and ended up using a larger motor (Sunnysky 2216) and a heavy battery (4S 2200) to get it set up. Even given the extra weight, the plane flew well, was quite enjoyable, and looked great in the sky. The day was a little windier than expected, but the extra power from the motor easily carried the plane through any moments of questionable airspeed.

It definitely is a fun and unique model!
