This Beta65X frame is customed for 65mm 2S whoop drone. This frame natively support 0x0x motors, like 0802, 0705 etc. Also it has a customed battery slot to support 2pcs 1S whoop style batteries. The FC mounting columns still match the whoop style FC boards. At the same time, we would like to keep it durable and light enough for a 2S whoop beast.
