3D Printed Plastic Foil Hinge and Flap

Over 11 hours of fatigue testing and still no sign of cracking.
Price is not obscene.
Ability to do a decent fairing at the intersection.
Simpler construction of mainfoil.
Most of the stiffness implications are sorted.
This might be a goer.


  1. Is that really going to be strong enough twist wise with the full length of the flap?

  2. There's a cavity to be filled with carbon of some description, which should provide sufficient torsional strength and stiffness.
