Hey Guys, Ken McSpadden here, one of the Viperjet flyers in the video.

I was able to program the DX18 sequencer to do the pulsed smoke with the help of Andy Kunz who writes the airware for Spektrum radios. It wasn't difficult, but it also wasn't something I could come up with on my own without his help. In fact, I'll have to look again at the radio when I get home to remember exactly how we did it! The basics are that the sequencer was setup so that when it was finished traveling from the beginning of the sequence to the end, it would reverse itself and travel back to the beginning, where it would reverse itself again and travel to the end.... creating a continuous back and forth seguence. Setting the values and speed of the sequence was pretty straight forward. To switch the smoke on and off, I created a couple of mixes. One mix would turn the smoke on constantly and was just a smoke pump channel to a set value... and the other mix would mix the smoke pump channel onto the constantly running sequence. I used a 3 position switch so position 0 would be smoke off, position 1 is constant smoke, and position 2 is pulsed smoke.

I'll go look at the radio later and try to give you some more specifics, but this might give you a few clues to get started on your own.

Thanks,
