Master tx is the DX9 - w/o touching anything, THR reads -100, AIL:-1, ELE:+3, rud:0, GER:-100, AX1:-100. Using toggle switch A for wireless trainer transfer with master override enabled.
The cursor moves smoothly with no hesitation while following stick/gimbal movement on the primary controls stop to stop.
Three of us shared the flight and half of it was with the slave, DX6i. After flight, aileron trim on the DX9 was showing some right - perhaps to combat the introduction of the left rudder(?) and a small amount of down elevator.
