Hi finally was able to test my jDrones quad outdoors but I'm not sure everything is ok, but maybe, having never flew copter, this is the right behavior.
Behavior I noticed in the quad
First problem I've seen is that the quad drift quite a lot forward/left. If I don't touch any stick it move a lot to one side.
Also, after I take off it climbs, but then when I remove just enough throttle to stop the climb, it starts descending, and it feels like there is no sweet spot where it doesn't climb or descend.
Yaw on the other end works perfectly.
Another thing I noticed is that if I pitch or roll, the quad looses height and I have to correct with the throttle to keep it at more or less the same height: I would have expected it to just move, not also loose a lot of height.
I checked the frame and it looks ok, no obvious misaligned motor or arm. Only possible issue I found is that a motor doesn't oppose the same resistance when I turn it manually as the others, but not sure this is a issue.
Are these normal behaviors that I should learn to counterbalance or is there something wrong in my frame?
I've attached the log: if you have a look at it, you'll notice that I have a lot o roll/pitch even when not applying any stick.
Any advice will be appreciated.
