John Dell replied to Colin Sadler's discussion Motors don't start until half throttle
"So when you calibrate the ESCs directly from the receiver they work fine?
If so just plug them into the APM and dont try and calibrate any more  (assuming you have not tried that already)"

John Dell replied to John Dell's discussion Naza M vs. APM 2

Per your question on transmitters and camera's... I am using Immersion RC 5.8GHz 600mW Tx with a FatShark NTSC 420TVL camera and a MinimOSD. Its all 5V and the transmitter / camera can be run from one of your ESCs"

John Dell replied to Dennis R.'s discussion Quad spins continuously 180 degrees non stop.
Did you check all the obvious stuff like motors oriented and wired correctly?  Prop on the correct way and in the right orientation?"

John Dell replied to Austin Suhler's discussion Level automatically adjusting in flight...
"For clarification, after you level your quad the pitch and roll show level....and then they become offset by 15 degrees while left on its own or do you need to do something to get it to show out of level?  Does this happen gradually or instantly? …"

Had a chance to compare the Naza M to AMP 2 this weekend and wanted to share the experience.The comparison was done on two similarly sized custom built quads at ~24" span running the same props, motors, PDU and ESCs.  The Naza quad had a Go Pro and…

John Dell replied to Graham Dyer's discussion Automated Parachute Drop / Camera Trigger?
I spend 45 min reading on how to trigger a servo to drop a chute and come to find out it was not working... same frustration. Hopefully a fix in in the works.... currently I am achieving this directly from the receiver"

"I have observed this on my Quad for every version of APM I have used  (I have had my Quad about 7 months).  RTL has worked maybe 10% of the time.... the remaining 90% is scary.  I have mentioned this on few posts as far back as April.  I know others…"

John Dell replied to Umer's discussion Indoor tethered testing Arducopter Hexa
"Do you know what caused your initial flip?

I have never flown on a tether but I assume some of the yaw problems you are facing may be a result of the tether restraining the copter and the controller compensating.

Throttle control is learned from…"

John Dell replied to Gent Armedo's discussion APM 2.0 Dataflash issue. Help needed.
"I had a similar problem as I was never able to access logs.  From CLI it also told me no dataflash card found.  I removed it and reinserted it and CLI was then able to at least see the dataflash but anytime I browse for logs there are none. Logging…"
