GP2 current sensor and OSD
Posted: Wed Dec 12, 2012 2:06 pm
Hello everybody!
Finally the rain stopped and I could make my first flights with the GP2 module. I installed the GP2 in the same airframe where it used to be the old one and I tried with the same config. The plane flies very well, I feel to say that much better than with the old one specially the Auto-Thottle that runs very smooth. I made 3 flights with it and the behavior is perfect in stabilized and in Auto mode with auto take-off and several waypoints.
But I have a cuople of problems with it...
First, I see that my current sensor does not mesaure correctly, It says that at full throttle is taking 16ah from the battery but I have tested at home that it drawns 32Ah. With the mAh consumed the problem is the opposite, when landed says that it where drawn 8830mah fom the battery but when I made the recharge the batteries chraged 3900mah that seems more realistic in accordance of the time fliying and past flights with the other planes.
Is there any option to calibrate the current sensor?
Second, In all the flights the OSD quit working. Simply dissapears the OSD data and you can see only the video. It happens randomly, sometimes at the time of taking-off and sometimes in flight. If you want to have OSD again I have to unplug and plug again the battery, rebooting the module does not make the OSD to work and in the log says "No OSD found" until unpluging. It also detects the video as NTSC instead of PAL that is what I am using.
Any idea?
Thanks,
Santiago.
