Is 12ga wire good enough? Then Deans should be enough contact area. I saw an article somewhere in one of the mags a while back that did a test of all of the major types of plugs out there and the Deans and traxxas came out on top having no detectable difference between the plug and a piece of 12 ga wire the same length as the plug. That seems good enough for me.
I personally would be a bit annoyed if deans changed their plugs. I have way to much stuff with the deans on there now to go back and update all of the plugs. I thought about going to traxxas or the new Losi 5mm bullet style connectors, but I did some math on what it would cost and it was a few hundred dollars
Kinda scarry actually. Makes me think how much money ive spent on this hobby over the years. if there is tah much in just plugs.
Also, the hobby city T-Stlye deans connectors are not as good as the "real thing" I bought some zippy packs a while back and was having issues with them not having the punch I thought they should. Then I noticed that the plugs that came on those packs were getting pretty hot during use. I took them off and replaced the imitations with the real deal Deans and all the issues were gone. No more hot plugs and punch as good as any of my other packs. The cheap plugs were the problem.
I have avoided the imiataions ever since that. Do what you want, but in my experience you get what you pay for.
$3 vs having issues with a multi hundered dollar brushless setup. Seems like simple math to me.
