This is my 3rd miniquad design based from ekcs frame (http://www.rcgroups.com/forums/showthread.php?t=1839667) but I made a some changes to support LEDs on front and back and some shock absorber on the 4 sides. I have not yet printed this but hopefully someone will. I'm pretty sure you guys will like it. Recommended motor is upto 22xxThis is made from Sketchup. you'll be needing some 4 spacers between the power distribution board and your favorite flight controller board. There are 10 screw holes in that frame. Do not forget to put the battery strap on the bottom frame before you screw the two frames together. It will be best to use epoxy as well to stick the two frames together then tighten it with screws. For cleaner build, shorten the length of your ESC wires and solder the motor connection on the ESC board.
