O man really the 42 slicks are out of stock already? Been trying to manuever funds around with they wife to buy one so I didn't preorder. Ugh. That's a bummer.
There are still some available for preorder at ADChobbystore.com. Rob is a great guy to deal with.
It won't work with Dean's connectors.
what you CAN do, though is just get two of those anti spark things and put one on both the negative and positive...hook both of those up, ESC arms, and then plug in the Deans.
Or you could simply have two deans in parallel. On one of the deans you hook up a resistor in series with the positive lead.
