A TT-Copter is a versatile multicopter designed for aerobatics. It was specially developed for fast flight and quick response to controls. One can fly all positive-pitch figures. It can also be used for hovering indoors. It was developed to be robust and withstand also hard crashes. With powerful motors, extremely fast maneuvers or heavy payloads are possible.

Development
Development began shortly after the release of the Silverlit X-UFO in 2004, starting with an improved control for the X-UFO. Due to financial problems, the project was unfortunately delayed for a prolonged period before it was finally completed in 2008.
Target Audience
- Funflier
- big thrust to size ratio
- direct control
- spacious flights
- precision flight
- loopings (also indoors)
- flips
- hovering
- camera flights
Technology
TT-Copter uses 3 piezo gyros for flight stabilization. The closed loop controller runs on an ATMega8 that also reads the remote control inputs and controls the motor controllers. A particularly useful feature is the automatic calibration flight in which the controller learns the parameters needed for the copter hardware it is mounted on. It is therefore not necessary to trim the PID controller parameters by hand.
Although the TT-Copter does not use an accelerometer, it breaks (if properly trimmed) its flight and starts hovering. Nonetheless, the pilot is not being constrained in any way by this function: all flight maneuvers known from helicopter flight except negative-pitch maneuvers are possible.
Technical Data
- PCB size: 51 x 51 mm
- PCB hole distance: 45 mm (63 mm diagonal)
- PCB hole diameter: 4 mm
- sensors: 3 piezo gyros
- motor controllers: standard PPM controllers
- battery: Lipo, from 3S
- remote control: 4-8 channel transmitter
- protocol: PPM (sum signal)
Feature List
- Auto learing: No need to set the control parameters by hand.
- Support for small and big copters.
- Hovering without ACC: Drift-free hovering without correction inputs from the remote control.
- No special expensive motor controllers needed.
- All settings can be chosen via the remote control.
- 2 servo connectors
- Support for x or + configuration.
Assembly
The PCB is completely soldered. Only the connectors for power, motor controllers and remote control receiver have to be soldered by the user.
