Thread: Trex 450 vbar up and down as if in high wind

Hi Guys,

I've just converted my 450 to fbl using the Align 3g head and a mini V-bar.

I have tackled most of my vibe issues but there is still some way to go in
this regard.

I'm finding the heli is moving up and down as if in a high wind situation.
This is the best way for me to describe the issue.
Tried a test flight indoors and the issue is still there.
Also tried various different head speeds to make sure this was not the issue.

I have also provided a link to the v-bar log below:

(pls right click and select 'save target as')

Also worried about this part of the log:

1:38 Antenna Switched The Signal from one of the sattelites was missing. The Main reciver is switched over to the other
connector. In Case of a single reciver connected, one frame was lost.
1:39 Antenna Switched The Signal from one of the sattelites was missing. The Main reciver is switched over to the other
connector. In Case of a single reciver connected, one frame was lost.

I'm only using one sat and the V-bar, so whats it switching over to?

I hope someone can help out with some advice on what to try next?

Surinder.

Any suggestions guys I'm really pulling my hair out with this?

Could it be a problem with the head itself?

Hi sacko,

Any suggestions on what gain values to try. Where do I find the controls for cyclic gain?
