$3.70Foamboard Aircraft Motor Mount – 1.5 deg

myminifactory

A 3D printable motor mount for a mid-size profile model aircraft with a wingspan of 1 to 1.5 meters (~ 39” to 60”), built from foamboard, cardboard, or balsa. The motor mount is suitable for many 450, 480 and power-10 size motors. It has built-in 1.5 degrees trust offsets, both downward and to the right, and pre-threaded M3 mounting holes for the motor. Originally designed to upgrade a “Hummer” for my club’s 2019 pylon racing season. It should work well with most foamboard kits, where a decent size motor with adequate offset trust is desired. The parts can be easily 3D printed, without any support, on a modern inexpensive 3D Printer. They can be printed with a variety of materials, including PETG, ABS and many other types of printable materials that are more heat tolerant than PLA. The motor mount must be printed with a heat tolerant material such as ABS or PETG. Do not print this part with PLA! This is because the motor can be exposed to high temperatures during flight or immidiately afterward, exceeding ~55 C (~ 130 F). At such temperature, PLA will likely deform, warp or even separate, thus causing loss of control of the model. I have successfully used this motor mount since early 2019. The upgraded aircraft flies true at much higher speed than stock, using a power 10 size motor – 1250kv, 3-cell, 600 watts power system, turning an APC 9x9E propeller.
