Default vBar NEO w/ vLink back flip issue

Hi,
Been experiencing this issue by this morning when I gave maiden flight to my Goblin Fireball.
Everytime I do back flip, I have to correct its position by giving left rudder. Almost 45 degree correction. In every position from upright to inverted. But when I do front flip, this issue is not so apparent.
Anyone experienced this issue before? How can I fix it?
Thank you for your assistance.

Note :
I am using vBar NEO 6 with Rescue with vBar vControl.

RPM is too low and the tail cannot keep it straight with the load of cyclic and collective. You can also try to increase elevator precomp.

Hi,
My first suspect, But when I do pitch pump, the tail is not moving, so I thought it's somewhere else and when I do front flip, the tail is relatively straight..I once read here but I forget where, that when we flip it forward and the tail can't keep straight then we have issue with phasing. I search all day long but still I can't find it.
By the way, I will check elevator precomp out.
Thank you.

Swashplate phasing that is not correct will mix elevator and aileron input, has nothing to do with tail input/output.

The fireball works great with default settings on Neo, but it needs high rpm, so follow manual on rpm recommendations.

Set up HS for 3800 rpm, I think it will run fine since here (on the goblin 280 section) they run 3800 rpm and works fine.
