It's actually worse than that... If you keep the timer circuit of the MJC intact, on a Spitfire Remote you'll have to hold the AUX button for at least that long (4 seconds?) to get the timer to trip. Gee, that doesn't sound like much fun... So on mine, I bypassed the timer and when I hit the AUX button for a 1/2 second or so, the MJC will give a spin. Hold it longer, it will spin until you release, and only spin when I hit the button.
That's the way I wired my MJC to my Spitfire, and so far, I am really happy with the setup. It gives me more control, the decoy doesn't spin all the time on a set cycle (boring...), it's really easy to keep your thumb on the AUX and hit it a few times every 5 minutes or so, and the MJC's batteries will last much longer.
Works for me...
