We just received another shipment of "The Jigs Up" soldering jig. It's one of our most popular tools. It's designed to allow for the soldering of Deans connectors, Traxxas connectors, and any plug that uses cup and bullet style connection (EC3, XT60, etc). It also has two alligator clips that hold wires together for easy patch jobs.
We use one here in the store every day, and it's made the task of soldering much easier. I highly recommend picking one up if you do any soldering at all. The jig runs $24.99, and we have plenty in stock.
