Problem with APM Mission Planner

Hi all,

I am a high school teacher working with a group of students to design and build a quad copter camera platform. The students have done a super job designing their own frame and mounting all the hardware. The copter flies extremely well in stabilize mode, but it does not follow a flight plan at all. It lingers in the general vicinity and climbs, but does not make a genuine effort to get to the waypoints. We have increased the waypoint P value but it does not appear to have any affect. We will download and analyze the log files tomorrow, but wanted to know if there are any suggestions for how to proceed to analyze this problem.

Thanks

I must have posted this question in the wrong section of the forum so here it is again as it pertains to APM planner:

I've been getting inconsistent results with the on board logger. My last flight was recorded just fine with the ground station, but APM never recorded the flight. The weird thing is that I had cleared the logs prior to the flight and when I tried to download the log, I got 2 completely worthless logs and a 3rd one which was just waypoints from an older flight.

The next day I ran into the same issue again.

I had a great flight in the morning with the onboard logger working just fine. Landed, downloaded the log, cleared the log. I then turned everything off for a few hours. I went out again in the evening for a quick flight. Loaded a new mission with 2 waypoints. Landed and there were no log to be downloaded again!?! Furthermore the plane could not hold an RTL circle and did not come back from it's intended waypoints. I had to fly it back manually. I'm not sure if those are related issues or not.

Attached is the ground control station log of that flight.

Any suggestions?

I have a feeling the board is too close to the motor or a source of EMF.
