Actually it should work off the analogs, I tried it once and I think it worked, it's been so long, but it takes mere seconds to try. It won't be sufficient if the servos are connected to the camera board, but otherwise I think it will work. But again, I haven't tried this since week 4 of build, and I
think it works. I'd be interested in the results of a test. Of course even if it powers on the lower power levels could screw with it, so give it a thorough test, and at any doubt, switch over the PWMs to boost the power level. The "problem" is the 7.2v on the PWMs are taken, interestingly enough from the 7.2v "Backup" Battery (Let's not get in to why a backup battery is a primary power source, I perfer to call it auxilliary battery) so if that dies, so does the camera, which does tend to kill the battery quickly, so I recommend use of the in-circuit recharger released by IFI.
