I built a LOC Stovi about 3-4 months ago with the 24mm motor mount option (instead of the 29mm). The instructions explicitly state that it "is designed for single 24mm or 29mm motor usage only". But on at least one retailer's product description page it states that this "is propelled by a mighty 7x24mm motor cluster". Now, I would NEVER ignore manufacturer's recommendations and build something potentially unsafe. But, I was wondering if anyone has flown this on a 7 motor cluster? How much nose ballast was added? What motors were used? How stable was the flight (slight veer, squirrelly, CATO, etc.). Just curious.
