MultiWii

Had the same issue once, was pulling my hair out until I found that I was missing the hash (#) in front of the define statement for the board type.

Check your board type. Maybe replace the entire config.h with a fresh one just to be sure.

What OS are you running?
Do you see the communication lights on the FC flash?
Are you sure you are using the right serial port?

Make sure you plug in the FC before starting up Ardunio. At worst disconnect all connections to the FC other then the USB cable, the FC is powered by USB.

Once the power starts to drop noticeably land and disarm, arm again and see if the power has been restored.

By disarming and arming again it will clear internal flight data, so if its software related you should see the power restore (I think).

I am having a similar issue. Did any of these suggestions work for you?

Have you calibrated the ESC's?

I have been using the bluetooth module form HK and the range is really limited (2.4ghz radio as well), getting about 10 meters before the connection is lost. Any experiences using a long range link?

The app is great, I love it! I will no longer have to take my laptop with me to tune the PID values and make settings changes. I am so donating to this one... The phone is running Cyogenmod 9 which is Andriod 4.04 so it passes the 2.2 min requirement. But I did notice that the Dashboard 3, maps and ...

well tovrin you were correct [face palm]. Calibrating the ESC's fixed the issue.

Thanks for the suggestion

Let me confirm the build details of the device, I am abit slow so it will take a few days

Change the MINTHROTTLE until the props start to spin when armed, then scale back if you don't want this behaviour.

What does the GUI show? Have you played with the EXPO settings?

Did you purchase the SK450 arms from HK?

I had these arms (not a dead cat) and could not get it to fly until the gyro filtering was enabled and even then it had issues. Have seen other people talk very negativly about the HK arms yet others don't seem to mind them.

What is the spec required for this app?
I have an old Samsung Galaxy S2 and this app does not appear, but a newer cheaper android phone does list it in google play.

No I have not. Using RC timer ESC that has been flashed with the simonK firmware. Does this mean there is no point in calibrating the ESC's ?

The frame has very little vibrations and the flight controller is mounted on foam. The GUI graphs look a lot better then my Tri

Having an issue with a new quad that I have been building. During its first flight I was trying to trim it in acro mode and it keep wanting to lean to the right. Had the sub trim set to -120 (thats full on the 9x) and it was not enough to correct it. Basically with the trim centred the aileron needs...
