Happymodel Mobula7 1s tinywhoop open prop conversion frame inspired by the flywoo firefly nano baby frame. Weighs about a 4g, 1g lighter than the happymodel ducted frame. Very strong, pretty much will never break as this frame with the mobula7 1s parts weighs around 23g without battery. Very fun to fly outdoors and even indoors if you're a good pilot.

Printed with PLA at 100% infill, 0.2mm layer height, 0.4mm nozzel.
