"It is a pity that this app is no longer being actively developed. Is it not possible to share development with the Mission Planner team?"

"First of all, I would recommend getting the Frsky FLVSS sensor since it can output cell voltages as well as total voltage of the LiPo.

I started by using the telemetry radios and the Tower GCS app. You will need an Android phone or tablet with OTG…"

"The extra current draw is most likely due to the heavier frame.

I believe the power module gives inaccurate voltage readings even if it is calibrated in Mission Planner. If the volts are incorrect, then it is very likely the amp readings are…"

"HobbyKing ships the Turnigy worldwide from any one of it's distribution centres in USA, Europe, UK, Australia, Hong Kong, . . ."

"The Turnigy 9XR Pro is a good inexpensive radio. You will also need a transmitter module that plugs in the back of the radio and a compatible receiver that mounts on the drone.
Check out the RC groups forum for loads of info and help…"

"First check the stick on the radio to see that it is recognizing your input of full left, centre and full right rudder. My radio has a graphic and numerical display so I can see the value (-100, 0, +100). Double check with Mission Planner on the…"

"I recalibrated the sticks on my radio and also in Mission Planner.
After 2 more test flights, the involuntary yaw has stopped :)"

"Scenario 1
If you do not check the box to verify height, the craft will fly to the altitude specified in the waypoint relative to the home altitude i.e. 100 metres above your home altitude. So if your home altitude is 20 metres above sea level that…"

"If you are using a power module, check this. I was getting similar drop off and suspected the batteries. I installed a small GT Power watt meter and the minimum voltage recorded during a flight was much higher than the flight controller claimed!"

"I have just done my 1st autotune (Pitch & Roll) on my S500 frame, 11x45 props and SS 3108-720 motors. 3S Nanotech 4500. ZTW Spider 30 ESCs. Weight 1450 grams.

The new PIDs were stored but I have no idea if they are "reasonable". They certainly have…"

"Hampus,

These numbers are being reported by the power module/pixhawk. I made the mistake of taking them as the truth and blamed the batteries! ;).
I installed a small watt meter which records the min voltage and max amps during a flight. In my case…"

"I am having a similar problem. 
After a recent crash, I am now getting low voltage (3S < 10.2) battery failsafe conditions after only 2-3 minutes which can be seen in the logs. The real time telemetry confirms a reported low voltage of around 9.5…"

"You do need 5V from a BEC, so you should not need to step-up.

Watch this for a very simple solution. They sell the trigger board and the micro USB<->Trigger cable. And they explain the settings in Mission Planner  :)
