back when fightercat racing was in business selling their esc's, I dealt with Ben. I purchased and ran 2 or 3 different esc's on my neu 2230 12-s rigger. I kept destroying them till i realized the cooling blocks were leaking. Ben was very good replacing the failed units until the defective blocks were discovered. Then they stopped selling esc's. These alien esc's are obviously the same esc's that were sold as fightercat esc's. Does anyone know if the leaking issue was solved? If it was, I would be willing to give them another try.
