While working on two recently acquired P2's that I'll call P2-A & P2-B, I noticed that P2-B has one V2.1 ESC with 960KV motor. The rest of the ESC's are not labeled so presuming V2.0, and the motors are unmarked so presuming OEM 2212. Since P2-A will be my main camera drone, I ordered a replacement ESC for P2-B that is supposedly a new V2.0, and ordered a T-motor upgrade for P2-A. Then I'll use one of those motors with the new old ESC on P2-B. This should make the ESC's and motors all match on both machines. However, the supplier described the ESC as V2.1 but in the picture he shows there is no V2.1 on the white SN label. Just the SN which would indicate it's actually a V2.0. He's double checking this now. If he posted the wrong picture and it really is a V2.1 ESC, then I'll have to buy 4 to make sure they all match in one of the P2's. My question is, is there any advantage at all to using a V2.1 ESC in a P2 that isn't using the 2312 motors? The T-motor upgrade is supposedly completely compatible with the stock V2.0 ESC's so thoughts?
