Has anyone used any of these? Any pros or cons? Do they work with APM?

Idea for time trial - fly a $100 uav:

GPS $14-28

Autopilot ~$25

Motor/battery/ESC $20

SPAD Airframe / servos $15

Update frequency according to manual:

et-318: 1Hz

et-3531: 1Hz

et-314: 1Hz

et-3631: 1Hz

em-411, I don't know

I expect all other modules to have the same rate, I didn't find their manuals so it's a bit guessing...

Hi,

good news, what is he update frequency of this module?

Thanks.

This is cool - it cuts the GPS price in half - and suggests a $100 drone may be possible.

DealExtreme is - or would appear to be - a broker - much like amazon is for much of its catalog. My orders arrive in spits and spats; but it all gets here.

Yes the re-fund only took aprox one week.. but indeed my buy was from a recently posted item thatbefore and after my order was in-stock and continue to be in-stock all the time but they never shipped it for 3 weeks... but that was only my case and dont mean that the same will happen to others :)

They are indeed slow with shipping, although in my experience it is better to buy items listed recently than items that are listed long ago. I always received my items, never had to cancel an order. I hope it was easy to get your money back from them...
Ramon Natal April 12, 2011 at 3:59am

Great deal but dont trust DE, had issues with them, never shipped a in-stock product for 3 weeks, so i decided to cancel the order... i have read that for other people they work just fine.. but that was mi case... thanks for the info. ! ;)
