Does anybody know , how can I test It ?, I don't want to test it out again .

devangflyer

Everything is ready for a new flight !

Ensure module is high enough above props plane. Compass is mounted on the bottom of the module so ensure you have set roll 180 degree.

devangflyer

Just tried it , with my hand holding it , works fine in stabilise , but as soon as I set in Loiter , it tried to get higher , but because my hand was holding it , it couldn't , BASICALLY THE PROBLEM IS STILL THERE . PLEASE HELP !

devangflyer

Is there some other mode , which requires gps other than rtl so that I can test the gps ?

Just tried it in alt hold (no gps required ) . It gives the same result , the problem can be in the barometer .

See, sometimes root cause can be completely different than we think. I hope you have followed guide of copter.ardupilot.com
There two important steps needs to be done carefully.
Compass and accelerometer celebration. Have you performed them as per guidelines given on the wiki? One more think ensure that compass is facing in correct direction(north-north). Also as i said check whethet roll rotation is set to 180 degree as the compass is upside down on the external module.

devangflyer

Yes I have done everything right , as you said .

devangflyer

I have contacted sp4mm3r to replace my controller , they should reply back by tomorrow

Does the Mission Planner HUD shows correct reading (ie E,W,N,S) when your copter is pointed to the respective direction?

devangflyer

Yes sir , but the barometer goes wild . Already contacted seller to replace it .

I couldn't understand what does it mean. Are you experiencing altitude drop while flying?

devangflyer

Altititude increase ! It goes up in full speed

phanivyas

Which firmware are you using? 3.1.5?

phanivyas

This is a known issue with 3.1.5 where the quad jumps upto 2m when you takeoff first time in loiter or alt hold modes. It seems this was fixed in 3.2 (still in beta stage). And what about the compass problem? You said the quad was moving diagonally, is that fixed? Not all GPS module has compass at the bottom so you have to make sure while selecting rotation roll in MP.

devangflyer

Is there a way I can try 3.2 ? It doesn't go to 2m , it keeps on going up until and unless I switch the mode . I don't know about diagonal as the only testing I have done with it after the crash is by holding it with my hand inside my room .
Can you tell me how to test for compass ?

phanivyas

Yes! You can try 3.2 RC7 (which is the latest) from your Mission Planner firmware selection page (select beta firmware). It might be risky, I would suggest you to stick with 3.1.5 until 3.2 is released. Compass test can be done through CLI (Test-> Compass) or by looking in the HUD. My GPS module has compass on top of it so I had to set Rotation Roll as None (0). Make sure you check this physically or by performing the test.
