2" Micro Quad - PETG edition by heliboy

Last crawled date: 3 years ago

Dragonfly is a 3D printed 2" micro quad designed to be made out of PETG, Nylon12 or Polycarbonate, which are reasonable strong materials. And it is designed to fly like a 5" quad... Providing a great platform for indoor flying, or simply to learn to fly quads LOS or FPV. Its especial good for back garden flying, crucially it is below the 250 gm weight limit for CAA or FAA registration.
The quad weighs about 104 gm and the motor can produce up to 250 gm of thrust depending on the battery pack used, providing an exciting but predictable flight experience.
Here is a link to a video of actual flight footage . To follow..

Filament for the Frame - you pas your money and takes your choice, I would go with PETG, White Nylon or Black Carbonite, for the flexible material TPU or flexible PLA work equally well… If you go for a fun pack I could print an number of alternate parts.
