FT sparrow (universal) dual motor wing mount

thingiverse

Hi, check out my other designs at https://www.thingiverse.com/BuiltBrokenGlued/designs **Update December 2018** I've got an updated version of this mount with the motor mounted up at various angles - Wing Mounted Adjustable Motor Mount V2 (https://www.thingiverse.com/thing:3326361) This design was made for the FliteTest Sparrow, but it can fit any wing with a flat bottom profile. It's compatible with 1104 motors as is. Thread specifications: - 2mm thread with 9mm between centers for 1104 - 2mm thread with 12mm between centers for 1806 I tried using a rear mount motor (1806) and a 3D printed part from Thingiverse, but the balance was over 40g at the back even with a 3S 1400mah battery at the front. The motors are situated forward of the COG, which I believe is 1.75 inches behind the wing's front edge. I designed the motor mounts to be secured using hot glue in a 5mm x 15mm slot. The cables then run through the wing body to the center and come out at the rear of the servos. The only change made from this printed design is opening up the cable hole for easier access, as seen on the last picture showing the underside of the wing. I need to test fly the plane now. Firstly, I plan on using 4-inch quad props for minimal clearance when the plane is grounded. I'm open to any questions or suggestions you might have.
