Blade 130X Tail Grip Flip Mod.

So I have been flying the 130X since it came out and have tried all the "fixes" with some success.
Recently I have had a problem, 2 separate times (maybe 3 if I think back to some of the first in flight failures). What I found was happening was that the tail pitch links were coming off of the tail grip balls in flight during hard collective "pops" or left to right tail inputs. This resulted in the bottom pin on the slider breaking and of course the helicopter would piro out of control and hit the deck.
I hate trailing edge control, so between that and the 2 repeated failures, I decide to give the "grip flip" a try.
Basically I just reversed the servo in the holder, reversed the tail grips, reversed the pitch links in the slider, and bent the rod to clear the tail servo gears now facing rearward and correct the new geometry because it is off to the side slightly now.
Test flew it and was very impressed with the "feel" of the tail. It felt more responsive, precise and best of all did not fail in flight from links popping off
Give it a try

Hi, why did you change the orientation of the tail servo instead of reversing the yawing channel? Wouldn't that have exactly the same result?
By "correct the new geometry because it is off to the side slightly now" you mean increase/decrease of the rod lentgh?
Thanks!
