The mark2 from GEPRC is the latest freestyle FPV frame that is the culmination of months testing and design iterations to give you the Mark 2, that is a zero compromise quadcopter frame.  At first glance, it may just look like any other freestyle HX frame, but when you take a closer look you will notice a bunch of smart design features that are listed below:

Key Features

• Available in 4 inch, 5 inch, 6 inch and 7 inch configurations.
• Aluminium central cross to add rigidity to the arms and protect electronics in a crash.
• Crumple zone on outer edges of arms to protect motors in a bad crash.
• Sleek 4mm arms to minimise wind resistance during flight (13.5mm wide).
• Separate arms to make replacing them easy and cheaper.
• Mark 2 uses YFS branded screws, 12.9 hardness, considerably stronger than most hardware other manufacturers use.
• Top mounted battery to ensure COG is in the centre of the frame (30mm standoff ensure battery is not inline with props)
• Rubber grommet for SMA/RP-SMA pigtail FPV antenna.
• Optional Gopro incliner

All of this combine to make for a strong, rigid freestyle frame that not only flies incredibly well, but is also super easy to build and repair.
