Made this plate so i can mount my NAZA FC and other electronics on top of my HAL frame. Note that this is for the hexa version so i dont know if it fits the quad. If printing in ABS you need to scale it up 1% or so. Also the holes needs to be drilled out to 3mm due to shrinking. There is 4 versions of this plate: hal_plate_small.STL is compatible with dome cover. hal_plate.STL is to big for dome cover to fit but features extra mounting holes. hal_plate_small_no_flange.STL if you dont want the extra flange edge. hal_plate_small_360.STL see image and you will understand :)Print in 0.20mm layer 2 shells 15% infill to save some weight Scale up 1% for ABS Holes needs to be drilled out to 3mm due to shrinking.
