Review: Good marine esc - Really happy with this esc Running 6s on a 3670 200kv motor Really cool Recommend buying the programmer I already own 2 of these 150amp esc's Would definitely recommend Update: I own now 4 marine 150 amp esc 2 are defective straight out of the box.. Didn't know it until I was ready to install... For $65. plus some soldering and connections. It's still a good deal. Frustrated to say the least.
Review: Simple power upgrade - Replaced esc in Traxxas Spartan boat..wow what an upgrade this paired with a new leopard motor pushed the limits on my boat...stays cool and simple to pair up
