This product is not compatible with any of my existing HXT 4mm ESC's or batteries. The red and black plugs are reversed in this product. The black should be male and the red should be female in order to match existing products. You have a quality issue.
ProgressiveRC Comment: Thanks for your feedback, we are looking at product revisions to make this a much more useful accessory!
