Holy StoneHS720G Aircraft Arm Kit (Left Rear)

The Holy Stone HS720 has been a great purchase. Good Quality drone with great features. I have purchase 2 more of their drones since this one

I really like the hollies down drones but the arms arms to the motors they are really really thin and weak then they tend to even crack and break even and folding them out I have glued them several times with a really good Apoxsee glue and but I think they just need to make a different material and maybe thicker components on the swing out on the arms to prevent breakage.

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

Works better than ever after replacing the broken arm. Very happy with this purchase.

TLDR:-Correct arm a HS720G front left (marked A)-Packaging the arm comes in could lead to damage in transit-Arm has 25 AWG wires (4) that need to be soldered in place-No guide for drone arm replacement so you're on your own-Replacement not recommended for a beginner*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 by tracing wires to their points.-cut the wires at the midpoint between the arm and the board-strip the wires back an 1/8in on existing wire attached to the board (do not strip the wire back on the new arm since they are pre tinned)-solder wires together and use liquid electrical tape to cover solder joints (2 coats)This worked for me and now the drone flys perfectly again.

Great company to work with easily use product when you crash it

The arm in the pictures for HS720 or HS720E Holly Stone drone. The description, however says HS720G, which in fact is what they sent. If you were trying to buy the part based upon the picture no that the picture shows the wrong arm for the wrong DroneI ordered two of them back to back because I thought maybe they just sent the wrong one but in fact the picture was just wrong. The second arm never arrived.I called Holly stone support and found out that my arm was under warranty for the first three months. I owned the drone and they replaced it for free. I ordered directly from Holly Stone for additional arms for all four just in case of future accident. All four cost me $53 total.

Perfect work just like the original
