i think the 530T does auto up and auto down. it can also control up to two motors

the 529T might only do auto down but not auto up.

i'm just pulling this stuff off the top of my head so i could be wrong. since the price of a 530T isn't much more expensive, you might as well skip the 529T.

 

I'm with this guy. In fact he and I were talking about this a while back...

I hope you get it to work.

 

Neat idea, but you'll REALLY be screwed if the top ever misfolds due to sagging elastic straps.

 

well the way these modules work, if that was to happen, wouldn't you just press the switch again to stop it in it's current position ?
