  1. Peter Hill (verified owner)

    Well pleased with this motor. On 2s 3000ma Lipo and watercooled ESC directly replaced a ED Racer diesel in a Vic Smeed Pirana 28” launch with better than original performance. Used original prop , shaft and uj coupling drilled/tapped to fit motor. Good battery life of 30 mins running. Only battery got hot!
