Hi, I'm using 3 program mixers in offset mixing mode on the T18MZ for sequencing the electric landing gear and gear doors on a M2000, the start/stop delay duration can be programmed up to 35 sec. On the M2000, the 3 main gear doors close when the gear is down, the 2 small gear doors (servo driven) remain open on the front wheel. I have made a small video of the sequencing programming but unfortunately it is in French...maybe you can have a look and find your way as the software of my T18MZ is in English. The programming of the M2000 sequencing starts at 8:55 on the video:
