Holy StoneHS720G Aircraft Arm Kit (Left Front)

TLDR:-Correct arm a HS720G front left (markedA)-Packaging the arm comes in could lead todamage in transit-Arm has 25 AWG wires (4) that need to besoldered in place-No guide for drone arm replacement soyou're on your own-Replacement not recommended for abeginner*For those who read this I'm writing a detailed guide for HS720G arm replacement on the Holy Stone Subreddit soon, so be on the lookout for that.*First and foremost, this is an OEM front left arm for a HS720G (has the letter A marked on it). When I received the arm, it came in an light weight packaging envelope with no added padding for protection. With such sensitive parts you need to do better Holy Stone at protecting them in transit, I mean atleast wrap it in a little bubble wrap bare minimum.Now for the meat and potatoes of this review. This arm was a little painful to work on. There is no official guide for the HS720G as to which screws to remove on the drone so the top board can be accessed it took some experimentation to get the top cover off. The arm itself has four(4) 25 AWG wires that you need to attach to the correct position on the board. The colors are Red, Yellow, Black, and a second Black. The two black wires have different outer jackets to distinguish them from one another. Make sure you verify which is which before attaching. The board itself has the point soldered in place along with hot glue or some sort of hard superglue over them so I would not recommended removing the wires from the points on the board to mitigate damaging the board itself.My recommendation for repair:-verify wire positions on the board bytracing wires to their points.-cut the wires at the midpoint between thearm and the board-strip the wires back an 1/8in on existingwire attached to the board (do not stripthe wire back on the new arm since theyare pre tinned)-solder wires together and use liquidelectrical tape to cover solder joints (2coats)This worked for me and now the drone flys perfectly again.

I'm very sad that I bought this holy Stone drone. It took off and lost control from the controller and broke one of the control arms, which now I have to disassemble the entire drone to replace it.Please hire some new engineers who think things through a little better and maybe I'll buy your products in the future

I received the item promptly but it has no instructions on how to install it. It has some wires hanging out and some screws but absolutely no clue on what to do with them. Will you please send instructions on how to install a Holy Stone drone front left arm?
