Agreed. Deans are totally worth it, especially with a G36 series weapon. (due to the multiple connections) In a G36, the battery connects to a small tamiya, then the fuse, then another tamiya which connects to the GB. My connectors were getting SUPER hot and the JG motor could barely pull my SP110. (like 10 rps at best lol) I added deans and my ROF shot up like 4 rps. (no joke, it's MUCH faster) Trigger response and battery life are also much better. If I bypased the fuse (while the tamiyas were still on) by connecting directly to the GB, avoiding the other tamiyas, it would shoot with about a 1-2 rps increase (when the battery is low) If I plugged it in normally, the gun wouldn't shoot. (battery had the same charge lol) That's how much resistance there was.
Hobbyking.com has deans for $10 shipped for 10 pairs. They are better than normal deans because they are made of nylon fiber so they won't melt as easy while you are soldering them on. They also have ridges on them so you get a better grip on the plugs. They are extremely hard to connect at first, so what I do is get some pliers and I just squeeze the contacts (? connector part thingy) with pliers a few times. It breaks them in.
