I've never ran connector adapters before so I'm not sure. They should all fit snugly together and stay that way. I'd consider using electrical tape to keep them securely joined and use a temp gun to check temps not just on the motor and ESC, but on the wires and connections also perhaps. Resistance leads to heat gains. You might be clued into a potential issue if you notice one wire getting hotter with use.Oh yeah, will do! It's really squirrley as is.
By the way, the connectors are giving me issues with current not being consistent. It cuts out and is slow to respond once it gets warmed up. This could be due to just bending one if them from a hard jump. Not sure. But I can literally feel the power running through the motor wires. Never felt them before, so not sure if this is normal.
