in atti it will mostly maintain level flight and mostly stay at when elevation i throttle it to. if I try and fly it in a direction it wont hold elevation very well. When in hover it drifts in what ever direction it chooses. if I dont keep adjusting with the ail/elev stick it will drift until collision or dead battery..lol
You didn't say what mode this was in (or I missed it). The copter will drift randomly on ATTI mode even after leveling itself; more so in manual, where it will hold whatever attitude you command, so you do need to continually correct out drift. So long as the drift is random (you don't see a continual tendency to pull in a particular consistent direction), this is perfectly normal.
If the copter feels twitchy, consider dialing in some expo on your transmitter. My quad felt much more twitchy in manual vs. ATTI, so I have my TX setup to add about 20% expo when I switch to manual. Made it much better.
bad CG makes atti and altitude hold change with tilting the craft.
the sunlight bit is a sudden fall, even with full throttle it falls till the sun gets off the controller
breeze will make it drift in atti, gps will add input to keep it in place. if atti is consistently drifting one direction, theres something called imu calibration. you put it on a flat table, hit calibrate, fly, add correction next time you calibrate it till it's holding relatively still. if your expecting it to jump up and sit in one place forever in atti your nutts. You have to fly these things. if that's a problem, your still needing to fly gps mode.
i believe your gonna be something like 8-10 degrees off set. standing behind the craft, the wire should point off to the right, say 8 degrees will get ya going. Theres a website to calculate it, but using that to start, calibrate the gps, then fly straight lines and see if it's going straight or flying a little sideways, turn the gps puck till it's flying nice straight lines, recalibrate it, and you should have a rock solid gps system
Aggrevated... I have to ask.. Your originally from England, Right? but now living in Florida?

lol No sir.
I HAVE spent a lot of time with them and several years in England. I dated an Irish woman for all of 6 years as well. I could hardly understand her when she got mad..lol Short little fiery red head!
That link takes me to a HTTP 500 error page :upset:
I just picked up on a couple of words you used.... "Bloody" is one of them, and "Complete Wanker" was the other. I was born in England and got a laugh out of the words, when I read them. lol
