Finally vibration free

[BruceHuang]

Hello guys,

I am so pleased because finally I have tuned my AP ship vibration free.

Just to share my experience, the main problems I have found is the head speed and blade. I set my headspeed at 1350 rpm and using align 800mm blades. Before I set my headspeed at 1200,1300 and 1400 rpm and I have had jello effect, then, I have tried RJX 810mm and rotertech 830mm semi blades, both give me the jello effect. Today, I got my align 800mm blades and set the rpm at 1350, then it's vibration free. The align blades are relatively lighter, I think it might be a solution to vibration. And the headspeed, it is essential, as many pilots have experienced that higher headspeed causes more vibration. Of course, I have balanced my heli very well. Mounting the batteries also very important. Before, I have striped both the batteries on a 2.5mm cf plates below, and because the weight and thin cf plates, it has caused up and down movement, therefore vibration.

I have tested the heli just now, the wind was blowing at approx. 15 km/h. The footage is good. I will try to get some shoot tomorrow at the countryside and I will post the footage. Right now, it is the rainy season at where I live, so no promises for the footage, but I will definitely post a short footage soon.

A short test footage, without any post, just a bit of colour correction.
