Your flight is good. I like it. I brought a helicoter from ShenZhen at a price 180RMB only fly up and down and a little bit forward. Once I lower than the battery power, it dropped on the ground. **** ...
Your 1st time?
???BATTERY POWER??? why lowering it
or you mean attitude control
The attitude control of mine ( actually all control but Yaw control)is not proportional.
ie ...it not going to lower 50% of the attitude when you lower the power 50%..
Think about this as you r driving a car.
Starting Point is A; your car position is B
you need to accelerate to get it moving...however the car will keep on moving forward until you hit the brake to decelerate ...
Steady attitude is like maintain the displacement from point A to point B
Change attitude require you to increase power as well to decrease power, vice versa.
Therefore,
Change in attitude is to add and remove vertical momentum on the plane.
Now, at the end to make it realistic in life, put slope(uphill) on the road as gravity acts on the helicopter. and as well air fraction.
at the end, here is the answer to your question, lower the power it will drop, when it drops , give it some power to stop the momentum of falling..
