This product comes with 25mm standoffs.
This is the Diatone ET160 V1.0 Carbon Fiber Quadcopter Frame Kit, with an included 5V BEC equipped Power Distribution Board.
Don't let the micro size fool you; the ET160 is a fully functional quad capable of brushless power, FPV equipment and massive fun!
It all starts with a carbon fiber top deck and 2.5mm thick carbon fiber lower plate with variable motor mount holes to accommodate a wide range of brushless motors. The arms are also integrated into the lower plate as one complete carbon fiber piece. Standard 36mm bolt holes for the power distribution board/flight controller are present on the top and bottom for a drop in fit. Cutouts have been integrated into the frame for most FPV components, including the camera and antenna feed.
