Yes, you're adding more resistance. You're right. But in reality on an average, stock gun it'll make three parts of f*ck all difference unless the connector is of such poor quality that you probably shouldn't be using it at all. Yes, changing the adaptor on the gun wiring to a Deans connector and going straight in IS the better way to do it but let's try and keep a modicum of perspective, shall we?

Also worth bearing in mind that a poorly soldered Deans connector will actually present MORE resistance than a properly crimped Tamiya connector. I agree that the Tamiya connector is the lowest of the low when it comes to contact resistance, reliability and the good old wiggle test but in terms of the amount of additional resistance we're talking about in the case of the OP it really doesn't make much difference.

I agree with all you say and will leave it there
