Printed fixed-wing flyer takes to the air for a short first flight

The hardest part of this story comes right at the end. After a maiden flight with high-speed passes, sharp banks and climbs over the fields, the airplane went down following a tight turn. The maker puts it down to loss of control and says the crash was very bad, yet still considers the whole thing a very nice project. That attitude alone earns respect in my book.



As for how it came together, this is a fully printed fixed-wing model based on the Model Z from Eclipson, with a nose-mounted propeller and a conventional tail. Even the landing gear came off the printer, done in PLA with flexible TPU for the tyres, on a tricycle layout with small black wheels. Around 200 hours of printing and roughly $30 in filament produced an airframe of about 800 grams.



The looks are a highlight: a matte black fuselage with light teal-cyan accents on the canopy, wings and wingtips, plus tapered wings carrying cyan and black markings. Before the motor powered up, the control surfaces were deflected slightly as a check, then the plane rolled along a paved path, accelerated and lifted off.



The open item is the damage. The airborne time is given as 30 seconds, and nothing has been said about how much of the airframe can be saved after such a hard arrival. For me that is the trade-off with printed designs: they fly beautifully when everything goes right, but the margins at the edges feel thin.

Printing the gear legs in PLA but keeping the tyres in flexible TPU looks like a smart split to me. Rigid legs hold the alignment on a tricycle layout, while soft tyres give a bit of cushion on a paved rollout. The trade-off is that thin printed legs look like the first thing to snap in a hard landing.

I would like to know how the TPU tyres were attached to the printed gear. Was the flexible material printed directly onto the legs in one pass, or are the wheels separate pieces pushed on afterwards? With small black wheels on a tricycle setup, that joint seems like the fiddly part of the whole undercarriage.

If a second airframe ever gets printed, I would suggest trimming the weight below the current 800 grams. Less mass to haul around in a tight turn might leave more margin before control is lost, and a lighter plane should also come down gentler on that printed gear. Even a modest infill reduction could help.
