Nice design but the motor mounting holes are too big for 1.4mm dia screw for 1102 motors. So I can not use this frame. Please design specific for the 0802 or 1102 motor mount holes for 105mm frame and 4 holes 2mm motor mount pattern for 105mm and 115mm frame. To much mounting pattern in 1 frame is not good.
