The German TT-Copter, introduced in 2004, was one of the very first multirotors on the market. Since then it has gone through many software and hardware versions and is still the best flying machine in heading hold mode plus is now also offering autopilot features with a lot of different sensors and flight modes.
All hardware is ready to fly and is combined on the main flight controller, the TT-CopterControl needed for flying in heading hold mode. It also includes a simple autohover feature for hands-free flying.
If more assistance in flight is needed up tu fully autonomous flight, the TT-HoverControl can be added (just plug and fly). With the TT-HoverControl the pilot can focus on taking pictures or watching a scene from above through video goggles.
The TT-Copter comes in RTF Versions, but also kits or parts can be purchased to build yourself a TT-Copter.
