Motor Nacelle/Mount For Twin Motor Setup - FliteTest Goblin

thingiverse

I made this motor nacelle for the FliteTest Goblin to make it easier to change motors. Most nacelles I found make it nearly impossible to change the motor after gluing the nacelle to the wing. Now you can easily screw the motor plate of and change the motor.It fits every wing with the widely used classic Flitetest airfoil with wing chord around 190 or 237mm. Flitetest uses that airfoil for some of their planes like the Goblin.It's made for a 22xx motor with 16x19 and 16x16 screw pattern. There are also versions for smaller motors like 14xx, 15xx and 18xx with screw patterns of 9x9, 12x12 and 12x16.You need some M3 screws for the bigger and M2 screws for the smaller ones to attach the motor plate to the nacelle. The holes in the cross section of the motor plate are slightly smaller so the screws cut a bit into the material. There are four holes to attach the motor plate but from my testing two screws are sufficient to hold everything in place.I printed this in PLA+ for testing but I'd recommend to print at least the motor plate with something more heat resistant like PETG.Print settings: 20% infill, 2 perimeters, top/bottom 3 layers, support on. 2024/01/03: Added medium sized (24mm diameter) nacelles and motor platesIf you'd like to see this nacelle adapted for other wing profiles or crew patterns just let me know or send me your wing profile. I'll see what I can do then.Enjoy and leave me a like or even a tip :-)
