Adjustable Electric Motor Mount for RC Plane (NTM 42-58)

thingiverse

This is an electric motor mount designed for my Phoenix Edge 540 (55.5" wingspan). It is made to work with any of the cheap 42mm NTM prop-drive motors from Hobbyking. I made it to be roughly the right length so that the prop on the electric motor when mounted sits at the same length from the firewall as the prop did when on the original nitro motor. Motor mount holes are roughly 48x48mm (designed to be used with the aluminum plate that is included in the NTM prop drive accessory kit also from Hobbyking). Firewall mounting holes are approximately 45x45mm. All holes are 4mm so should work fine with 4-40 hardware or 3-4mm hardware. The mount is likely extremely over-built but I went for safety and durability! On 6s (22.2v) this motor is going to pull like crazy!

Print Settings Printer: Turnigy Fabrikator Rafts: No Supports: Yes Infill: 100% Notes: I would lay the mount on its side and print using lined supports for the middle, circular section. I would recommend 100% infill for maximum strength (remember this is essentially holding all of the weight of the plane plus any other forces the plane may experience). I am printing the piece in ABS, but PLA would probably be fine, too. NOTE: I would recommend doing several bench test to ensure that this mount is strong enough! It must support the entire weight of the loaded plane and more!
