I asked to let me deliver a second package, thinking that missing parts in the first package, but the second package is identical to the first ... the hardware is functioning quite normally, but there is no flak and plotting control device despite the fact that the manual describes how to mount and use them !! it's a shame and I feel that Amazon is doing there savings candle-end. Also, I do not know how I can get these accessories. However, I saw the guard because I now urgently needed.
