Three independent motors and propellers should theoretically provide 510 g of thrust, so there are some mechanical losses when combining 3 of them in a single assembly. Once integrated into the engine housing, the three motors produced 490 g of thrust at 5700 RPM, with a larger propeller. As a baseline, tested a single motor on a scale with a 4.25-inch propeller on a scale, which produced 170 g of thrust at 21500 RPM. A variety of propellers can be mounted using 3D printed adaptors. A 3D printed conical gear is attached to each motor shaft, which drives a single output gear and shaft mounted in the center with two bearings. The assembly consists of three “180” type brushed DC motors, mounted radially in a 3D printed casing. As an experiment,, wanted to see if he could combine 3 small DC motors into a usable RC aircraft motor, effectively creating an electric radial engine.

But, it does fly, and it is a great step toward the next iteration. A mishap with the Center of Gravity demands a last minute design change which renders the rudder almost useless. You can see evidence of their excitement in the graffiti on the wings and fuselage- surely a huge success on that front! As for flying? Four large motors provide locomotion, and it’s barely enough to keep the beast flying. The build is anything but ordinary, and kids are involved in the construction, although the video doesn’t elaborate on it very much. A very light EPS foam is used to cut out the flying surfaces, while a denser green foam board is sourced from the local home building store to construct the fuselage. , known for building manned ultralight electric aircraft from foam, was roped in as the designer of the aircraft. ![]() Did it work well? We’ll let you be the judge after taking a gander at the video below the break. What do you do when you have a whole warehouse sized facility and an industrial sized CNC foam cutter? Clearly, the only choice is to build giant RC aircraft, and that’s exactly what the folks at teamed up with the illustrious to accomplish.
