Basic Foamie nacelle for quad motors

thingiverse

This is a basic nacelle for lightweight foam fixed wing aircraft. It should hold everything from an 180X to 220X size electric multirotor motor. Like I said, its a basic nacelle for home made foamies or for converting a single motor tractor/pusher style plane to a twin tractor. These would also certainly work for a single motor aircraft, just keep in mind that there is no angle to offset rotational torque. I have done a total tear down and rebuild after losing some tabs while screwing the firewall into the nacelle. So far the parts are sliding together without prep. The screw holes are holding up, and the rings are very supportive of the firewall. I also added thicker supports at the bottom corners of the plate and added some chamfering/fillets to make things less blocky and square. Thanks to my pal Stephen, I added screw holes every 45 degrees to allow more flexibility in motor/wire position.
