Brian Buaas has been running my old Dave Frank Executone to NAMBA two lap records and Electric Nationals class wins. It was equipped with a Scorpion HK 4035 800, a Castle ICE 200 lite ESC with added water cooling, and two Gens Ace 5300 4S packs in series. The Scorpion isn't cheap, but it's durable as is the Castle ICE ESC. The cost should be in the $550 to $600 area depending on the street prices. We melted a lot of less expensive components before settling on these. We're pulling around 150 amps, but could pull more with these components, if needed.
Brian added to the battery with 2 more 4S 5000 mah packs giving an 8S 2P setup and did pull more current at the nationals, toasting one Scorpion. He propped down and still easily won with a spare motor. I just finished converting the boat to Neu power with the 1527 1.5Y. It should be faster still with currents in the 200 amp range. The increases in Scorpion pricing make the Neu motors competitive.
