I wanted to share some videos of the finished setup, and runs with the ML Boatworks 54" Formula 357 SR1. I was pleasantly surprised, and the 15+ minute runs times, were even better. The setup is a Leopard 5692, 540kv motor, castle 200a esc, 4s lipo setup with 10800mah of capacity (4s2p), and an x470 prop, cut down to 52mm. The loaded rpm on this is only around 7100rpm, but it is plenty fast! Enjoy, Mike
