450 450X with new Align DS425M

[Wolf714]

well thanks to some good advice here, & a good bit of trial/ error/ minimal problems- plus good luck- I finally got my 450X airborne again with dew worries.

the only issue I have now is pretty odd to me, because the Align DS425M is obviously a much better quality servo than the stock eflite the bird came with, &, which inexplicably failed without warning.

the tail wobbles/ wags ever so slightly, & while I go up & down numbers with the DX6i gyro % setting, either it wobbles faster the more I increase the gyro value, or it gets sluggish as I go down the scale.

to the credit of the old, stock, now tossed T- servo, this regime of 'wobble/ wag' never happened! not once. & the gyro gain was way high too; up to the mid, upper 70's.

now I've got the T- servo dialed in @ about 59- 61-- kinda just trying to get a feel for it again- but like I said, previously the tail was ROCK solid; no movement whatsoever.

any comments or advice will be appreciated, & also again thanks to those who helped me out after my last posting here.

Not that i'm an expert on 3GX, but once you get rid of the fast wag with your gyro gain in the radio.
Go into the 3GX settings and reduce the tail lock gain until the wag is gone.
I'm just reading this from what I have found on the inter web
Hope it helps

3GX means nothing to me! I have the Spektrum AR7200BX which I can make adjustments to, & have already done far as setting up my 450X with a 'foreign' T- servo; the Align DS425M

The thing that finally got me in the air again, with enough confidence such that I did not expect a mechanical/ electronic failue, was changing the 'REVERSE' setting on my DX6i radio from 'R' to 'N' ..

As I stated in my last post the tail either wags really fast as I increase the G- gain; the % numbers on the DX6i, or it gets sluggish & wobbly as I go down the scale..

I wonder if on the DX6i there's a way to fix this, besides going to the AR7200BX.. or, if I do need to adjust th beastX, what parameter do I access & then change?

I read in a post from another site like this, that the feathering shaft damaged in a crash may have caused a similar issue. Based on how I see the rotorhead behaving now, it all looks 5 by 5; completely good.
But I do realize these machines are incredibly sensitive -- so the trick is to troubleshoot it down to minutia -- much of which I simply do not understand, much less am I aware of

Sorry Wolf,
Had it in my head it was 3GX
With the beast X. Get rid of the fast wag as I said before by adjusting your Radio Gyro gain.
Then turn up Dial 3 on the BX which controls tail dynamics, until it stops drifting back and forth.
