I think I read that the D pod is really uncommon to require tuning. It's more for less typical platforms like dual boom with inverted V-tail, when then only small adjustments.

Good luck, Charles.  Get er up high. 

I'm about to start changing PIDs.  One method I read about is to adjust P and leave I and D at zero, then it all gets kind of fuzzy when you should add I and D, but I is for controlling overshoot and I'm still clueless about D.

almost made it out for a fly today but the wind kicked it up a notch too much

Thats an ok module its really small too!, and great price Anwar!!

as long as it allows for serial output using the pins needed without the additional purchase of a breakout or interface board it will work great

Here the MTK GPS module is for just $14 but I am not yet sure:

Good, I should be able to follow it when I'm ready for a GCS. 

I raised the pitch compensation in the PID section which should help when it reaches HEAD_MAX.

Still a work in progress....

Well Harry it was the best 32 dollars i ever spent !

im not sure on the distance to remain connected yet tho

but it displays all the pitch yaw roll ect on separate gauges in realtime

might be usefull for tweaking pids ..that im really not looking forward to doing lol

Thanks Chris, I will pm you

Makes me want to have telemetry.  Glad I could help, Charles. 

I crashed again today, but not because of anything the Ardupilot did.  I was coming around to land and got too close to some light poles along the road.  I goosed it and tried to climb and clipped a tree.  It spun like a top and spilled its guts in the road.  I looked and a dump truck was coming so I ran out in the road and held my hand up while I picked up the parts. 

The flight was useful as I'm ready to start tweaking some of the PID's.  I reduced HEAD_MAX to 3000 and with the stick all the way over, it almost held altitude.  I think that means Pitch_Nav needs increasing so it will add elevator sooner.
