Currently fixing an inspire with a broken "wing". I found a carbon fiber tube replacement and cut a "sleeve" for the fix. I saw this on YouTube but decided against making one, bought a CF tube and cut the sleeve. I was very surprised on how it fits. It fits like a glove inside the inspire arm. You actually have to pinch the sleeve together and slide it into the arm. Once inside, even with out the adhesive, its in their good. Obviously you use adhesive to hold the sleeve in place that connects the broken arms together. I will be adding some filler adhesive to the outside after the inside adhesive is dry and cured. Please Note: This fix is if you are out of warranty and don't want to wait for DJI, or don't want to pay 400+ for a new arm. If anyone would need one, I will only have 9 of them. I'd let each go for $20 bucks shipped if someone would need one for a fix. If you are outside the USA the cost may be more based on shipping. PM me if your interested.
