武器的设计，以适应V500 / H550和DJI Flamewheel多转子帧。
These arms are of very good quality. They are 25mm (1 inch) longer than stock DJI arms. They weigh exactly the same 55g as DJI arms and they are stiffer than the stock ones. Essentially you will get F600 out of F550 board and F500 out of F450 board respectively. This will allow you to use 11 inch props on either board if you choose so.
The LED boards that come with it are of great quality too.
Very well packaged - each arm in a sealed bag, a pair in their own box and shrink wrapped on the outside.They are realy good. The visibility is very good. Perfekt. I would buy again.
