I understand the Hybrid Titan for the dual is one titan and one bowden. The Titan Dual is two titans either side by side or front and back; depending on the carriage mount. Are most Dual owners going with Dual Titans? Which carriage mounts? Is there a RC6 firmware for Dual Titans? What motors are recommended for the Titan Dual? My original or would I gain anything from pancake style? If so, where to source those from? Wiring?
