  I've been using the APM 2.5 controllers that come on the Cheerson Cx-20 and the Quanum Nova, and a Pixhawk on a hexacopter 550 build and never had issues with GPS lock or low satellite counts, yet hear all the time about GPS issues in the various multirotor forums around the Internet. I just assembled a HK H.A.L. quad and used an APM 2.7 FC and for the very first time ran into GPS issues with a VERY long time to lock and low satellite counts. This problem would go away when I plugged in the USB though. After chasing ghosts thru the power system and adding filters, etc, I noticed that when the dome where the GPS was mounted was lifted up, it was a little more than an inch further away from the APM than when it was down in the flight mode (GPS is mounted on the top). So I ran some copper tape on the inside of the dome under the GPS to shield it from the APM and now get as good of reception as I get on both the APM quads (CX-20 & Nova) and the Pixhawk on the Hex! So my question is to people having GPS reception issues, how well is your GPS shielded? If you are having problems, is it shielded well enough?

  @Ali you can use basically what ever quad for that. It can be even 2 sticks crossed with motors mounted on end of those. As long as its all symmetrical. Symmetrical frame just makes initial software development more easier. I would say have/make frame that has motor to motor distance something around 60-65cm for start.

  • 1. @amirhossein, no you should not do that. You only need to calibrate accels if you change orientation of your autopilot for example when you change it or do bigger modifications to your frame. Also rarely when we make bigger changes on software, accel calibration is needed. 

    There is quick accel calibration check when you connect your mattery but that is different calibration initiated from MissionPlanner or other GCS.

  It's possible to find older vers of 3DR services?

  I have Mission Planner 1.3.3.1 and Arducopter V 3.2.1, but so far I could not open nor play any log, What I have to do to display the logs or play them?

  I click in the download log and play log button in the Planner without any result

  Thank you

  I think Richard's solution is better :)

  Just created a mod for apm planner 2.0 that allows you to trigger flight modes using keystrokes. I'm working on another mod that will allow me to use a midi foot pedal board to trigger flight modes and expression pedals for rate/gain tuning.

  If anyone is interested and would like to take advantage of key commands for flight modes, just reply here and I'll forward you the details.
