I've recently bought a FT Radial 1806 Brushless Motor and a BLHeli 20A ESC (xt/60). They aren't connecting, I know the male FT motor connectors are be 2mm banana plugs, while the ESC might be 3.5 or 4mm tube. Can anyone confirm what the ESC connector information is? And what would be the most cost effective way of solving this issue? The battery I bought comes with an xt/60 plug which works with the current ESC.
Thanks in advance. (Photos are attached)
