I've been trying to fly my arducopter for the first time. But it just won't take off straight up vertically.
The way i'm doing it, is i'm slowly pushing the throttle and expecting to see it slowly hovering. and expecting to see it stabilize itself. Instead, the copter drags lifts itself diagonally and drags itself to the wall. Does anybody know what might be the problem? Am I doing the take-off correctly by pushing the throttle slowly, instead of full throttle in one shot?
oh, i forgot to mention, the radio is calibrated well, the motors are also calibrated well. And even if the motors are slightly not calibrated, I still expect the copter to auto balance itself, correct?
Thank you, guys..
I had a similar problem last week. I found that I had one motor down on power and replaced it. But I found in previous experiences a slow increase in throttle at the start of flight is does not do as good a take off as a more aggressive setting.
I think your expectations of how your quad will fly may be a little high, it generally has to be controlled most of the time especially if it hasn't been tuned, even then expect drifting when hovering and constant throttle changes to maintain the same height. A quad is easier to fly than a RC helicopter but only just. A few seconds normally is the most you can take your hands off the controls, unless in loiter or one of the other navigation modes.
Throttle slowly is the correct way to take off, I normally throttle up until it just lifts off, controlling it's attitude all the time, I then keep it low in ground effect for a few seconds just to make sure everything is fine and then increase the throttle slowly until it's at head height and out of ground effect. It flies a lot better up out of ground effect.
thanks for the input guys..
I manage to fly it last week (then took a break from it for a while)
So Graham, I completely get what your saying now. So when you say "... if it hasn't been tuned", how can we tune it?
