Looking for an affordable trainer quad that you’ll still enjoy flying after you've mastered your moves? This H125 micro quad might be the right choice. Measuring just under 100mm long, about 75mm wide, and 125mm diagonally, this is the perfect medium-sized micro quad for just about every skill level and every age. Weighing in at just 45 grams fully-stuffed, including the battery! We've based this micro around the 7mm brushed motor because we've found that they’re inexpensive yet get the job done. Instead of using screws and aluminum spacers, the quad is designed around a peg system that saves a significant amount of weight and makes construction and repairs a snap. Using a Turnigy nanotech 260mah lipo, you will get about 4 1/2 minutes of flight time. If you want to see this quad fly check out our micro quad flight video. If you have any suggestions on how we can modify our design to make it better just leave a comment. If you are looking to make and easy remix, our designs are also publicly available on Onshape. Please refer to links included at the bottom of the page for specific links to our designs. If you like this project, make sure to check out our other cool science projects on our youtube page!

Use your default settings
Top Plate: Print in PLA or ABS with no rafts or supports. Print with 4 shells and 15-20% infill. You may have to flip the design in your slicing program because of the LOSI slot.
Bottom Plate: Print in PLA or ABS WITHOUT rafts, but WITH supports. Print with 4 shells and 15-20% infill.
Spacer Pegs: Print in PLA or ABS with rafts and supports. Print with 3 shells and 100% infill. We suggest printing at least 4 at a time so that each peg has time to cool before another layer is added, ensuring that your pegs don't deform.
UPDATE (12/25/16): New design with squishy rubber Ninjaflex feet. These feet help absorb and disipate the impact when you have a rough landing. This requires a dual extruder printer capable of printing Ninjaflex. Use the same settings for all of the PLA/ABS parts, but print the Ninjaflex at 10-15% infil with two shells. There are four .STL files of the rubber feet. When dragged into your sclicer, make sure to reset their positions so that they align with the plastic base!
Assemble Your Micro Quad!
We've created a super in-depth tutorial video on how to assemble your micro quad. We've even created an entire step by step tutorial slide deck that’s laid out for teaching an intro class about drones. Our tutorial includes detailed photos of the quad through all steps of assembly, clear instructions on how to perform each step, and a complete CleanFlight configuration tool walkthrough. Our step-by-step student slide deck can be downloaded along with the .STL files on this page. Stay tuned for detailed repair videos, slide decks, and flight videos.
