"If you want to stop the motors, first flip upside-down.  Then as it falls, the motors will spin in normal direction and can easily re-start. "

"More or less the same history, I was pushing it to its limits, I wanted to descend as fast as possible, one second after cutting the throttle it started to rotate in all directions like crazy and it finally... crashed :| "

"Hi, Yeah its not so good that the motors can stop completely when taking down throttle - because they might just not restart. I have done this stunt 100 times with my MikroKopters - no problem because they idle at zero throttle. The first time I…"

"Just don't forget you can't power everything from the USB! And I'd be concerned connecting both your main battery and the USB together, because of no diode protection. "

Keith S replied to John Campen's discussion Missing APM board component . Diode?
"That would work! It's a little bit larger, SMB instead of SMA. Tiny bit longer 4.3mm vs. 4.0 and a bit wide 2.3mm vs. 1.7mm. Keith"

Keith S replied to John Campen's discussion Missing APM board component . Diode?
"You could short the diode position with a jumper wire, then the rx side would power the APM, but be carefull, and remove the jumper before connecting the USB. That should work till you get a schottky 1A diode in there. Maybe a switch for now?"

I have done absolutely nothing with the Remzibi OSD, I purchased it assuming that it would read data from the APM1 or APM2, not so.  It appears the MinimOSD will but I am not sure about the software just yet. My impression of working with DIY Drones and open project is like trying to put together a jig saw puzzle made up of several puzzles mixed together and half of the pieces missing with the picture on the box totally unrelated to parts inside. My luck with the APM2 has been not to good, I took it back so it could be tested.  But I am trying to fly it in Acro mode but they only fly it in Stabilized mode and they plan on dropping Acro mode because of the problems it has!!!  Oh well. I have not given up on them, I trust that things will come together and it will be a great product.  They have a very good foundation and are working very hard on development.  Their goals are the same as mine, for now I am working on the mechanical side of things.  I have been very successful at removing vibration that is messing up my video ventures and I am very impressed at how well the ducted fans work.
