Titan Tornado
The Tornado is a 1-meter twin tractor designed for maximizing your FPV fun. It packs a tight punch in a small form factor while being a swiss army knife in terms of configuration. Featuring a swappable nose and tail-cam, Tornado can be configured for almost any kind of FPV experience you desire. Multiple noses supporting multiple cameras are included, as well as blanks for the community to modify. Designed with aerobatics in mind, it’s got large control surfaces ready to command ludicrous pitch/roll rates and maintain stability at any speed. Of course it wouldn’t be a Titan without space for large batteries – allowing for ultra-long-range flights if desired. Wing bays on either side ensure maximum antenna separation, while the smooth contours reduce interference drag and help Tornado cut through the air like a hot knife through butter. Better call your weather-man, because this plane is sure to stir up a storm at speeds of over 220km/h.
