When it works, it seems to work well. It has not shown any of the glitching associated with the old DSM2(?) when using both types of receivers on my DX4C.

However, the transmitter and receiver occasionally don't sync properly on power-up. I must cycle the power on both transmitter and receiver (sometimes several times) to get the link firmly established. When one must get on the track quickly, with other racers waiting to start a race, it's a real pain.
