"Have a look on ebay for a 'screen tool'. They are a plastic tool which cost a few bucks and a perfect size to get under the connector and lift it safely.

"An investment of a couple of dollars from Amazon or Ebay will gain you what's known as a 'pry tool' used in mobile phone repair. Just google 'mobile pry tool' and you'll find plenty of examples. They look like this:

"Thanks for the warning, Randy.
I can't locate the link for the manual download of -rc5 for the downgrade. Are you able to advise how to obtain it?"

"70% throttle to maintain a steady hover is incredibly underpowered. Something's clearly wrong. If you're confident that there's nothing wrong with the 'copter, have you tried a different LIPO?"
"I can confirm I'm seeing the same behavior but am not sure if it was me upgrading to this firmware or MP."
"You shouldn't need to touch those when starting out.
The tunable parameters for flight are on the "Extended Tuning" tab. Their default value should get you a reasonably stable take off. You may need to slightly tweak to keep it stable, but it…"

"The default PID's are normally pretty acceptable to get you in the air on your maiden. Have you experienced any problems with the settings?"
"It certainly sounds like a Sync issue to me. EG: https://www.youtube.com/watch?v=5pBdDMxWsgs
You absolutely should have signal and ground wires attached to your APM/Pixhawk.. Leave any BEC power disabled until you've sorted the issue."

"Don't trim the radio.
Setup your flight controller properly and allow it to manage individual channel throttles."

"Yeah; eCalc isn't perfect but it gives a good indication on performance. I ran the numbers on your existing setup (making a few assumptions) and got this:
It's not exact, but eCalc tends to be conservative. I'd say it's close enough to match…"

"Just to add to this, if you can't match up Ecalc to your specs without a premium account, I'm happy to help. Just add the AUW, the prop specs and the battery voltage."
"Sandy,
Your copter is significantly underpowered. You'll need to improve its lift performance.
It's probably possible via a change to your props. Put the appropriate details into Ecalc and see if you can change the props to get your hover at…"

"Hi Jeff,
I'm by no means an expert but a brief look at your log seemed to show some strange inverse relationship between your two magnetometers on the Y & Z axis,
Try recalibrating the magnetometers."

"Hi all,
Does anyone have any thoughts on how to debug this?
Many thanks."

Hi there,I've been slowly building and tuning my first quad and have noticed a small anomaly I can't figure out.For some reason, my GPS' relative altitude is showing a negative value both before takeoff and after landing. The value is not consistent…
