Hobbywing 10BL60 is what I've been using in Seydlitz and NC. I also have the brushed version in my Iron Duke & Lutzow. The fans are removable for our purposes. View: https://www.amazon.com/Hobbywing-30105060004-Quicrun-WP-10BL60-Waterproof-Controls/dp/B00P8CQYZ0
Does anybody know of any dual brushless ESC setups? I've had good success using dual brushed ESCs from the robot marketplace and similar as an all-in-one board for certain boats. One ESC for propulsion, the other for pump. But I haven't seen any similar brushless setups.
