just a little update on my V911 hiccup or jerking problem, i think i got it solve... but need to see later if still got hiccup...
btw, i did notice, it is not only hiccup, but my V911 suddenly after like a 2-3 minutes flight, it started to hover about 5 cm from ground even in full throttle.... so, i suspect this thing...

the motor is rotating while it is flying, so as you can see from the pic, i think the force exert on the wire from the holder make a disruption on the power, myb... LOL... btw, when my heli only can hover for 5 cm only, i did try rotate the motor like in the picture on the right, and it can fly high again, then after a few minutes, it hover 5 cm again and when i check, the motor again rotate to the early position as in the left picture... so i rotate it back, and superglue it...
myb this will solve the problem...

p/s: u also can see that the red wire got some black mark, i think it got burn from the exert force from the holder...
