With aerial photography being increasingly promoted, DIY hobbyists have lots of choices about  the mainframe. Here I may strongly recommend DJI F330, Adopting 330mm frame made by fiberglass while the arms utilizes durable nylon. The flame wheel supports NAZA, KK, MK, MWC which can achieve hovering, cruising, even rolling, etc. More and more people apply the frame high-mobility activities like photography, advertisement shooting and other aerial activities.
DJI F330 main frame plates utilizes high-strength compound PCB material, which makes wiring of ESCs and battery easier and safer on the lower two frame plates which is also the power distribution board. Assembly is a breeze with pre-threaded brass sleeves for all of the frame bolts, so no lock-nuts are required. The quadcopter frame utilizes one size of bolt for the entire build, making the hardware very easy to keep in order only requiring one size of hex wrench to assemble.
What’s more, the overall frame design provides enough space when assemble to fit an autopilot systems between the top and bottom plates of DJI F330. Besides, the frame is very easy to build and held together by a set of shouldered bolts which pass through the holes in the top and bottom frame plates into the top and bottom of the arms. The total of 6 bolts per arm holds the frame plates in place and ensures that the frame is very solid, making it able to put up with a great deal of use or abuse!
Furthermore, DJI F330 frame features large mounting tabs at the front and rear of the main frame bottom plate for mounting cameras or other accessories, which makes a great way to take aerial video or fly FPV without the need to add any additional mounting brackets. Additionally, the frame adopts colored arms which are great for orientation. And pilots can identify flying direction in the right way without the need for different colored propellers. And the frame perfectly supports KK MK MWC controller as well.
