Ph2t decided to do a frame conversion for the Tello as the next motor failed. He has ordered a 135mm CF frame off eBay, take off pcb and put it on the new frame. Also he tried to change the stock battery, using a LiPo one insted. In such a way he wanted to upgrade Tello – improve its capabilities and make it a little bit lighter. But, unfortunately, he failed. The only profit he got – he changed camera angle.
Follow the link to see how he did everything step by step and maybe you will be able to bring his experiment to the end.
