thingiverse

Looking for an affordable trainer quad that you'll still enjoy flying after mastering your moves? This H125 micro quad might be the perfect choice. Measuring just under 100mm long, about 75mm wide, and 125mm diagonally, this medium-sized micro quad is ideal for every skill level and age group. Weighing in at just 45 grams fully-stuffed, including the battery! We've based this micro around the 7mm brushed motor because they're inexpensive yet get the job done. Instead of using screws and aluminum spacers, the quad is designed with a peg system that saves weight and makes construction and repairs a breeze. Using a Turnigy nanotech 260mah lipo, you'll get about 4 1/2 minutes of flight time. To see this quad in action, check out our micro quad flight video.
