Default mini v bar aileron bobble

after a crash and a rebuild i have started flying my logo 480 with vtx blades, i am noticing an aileron bobble when i start a forward flip , i'm careful not to give an aileron input and i can also see it in tik toks, i did rebuild the head with new thrust washers and dampeners , which i set to soft , and i'm running 2100 headspeed , i tried increasing the head gain but the bobble got worse , i also lowered the elevator optimizer by 10 down to 35 , any ideas as to what i should try next?

Hi guy, look that to check if has inverted the thrust bearing during assembly, or put dumper more hard, or check the feathering shaft ij not bend.

If this is your first set of VTX blades on this heli,i would turn down your rotor gain 10 points at a time until the bobble goes away.
I tried a set of Vtx blades on my 700 heli from a set of Cyclones and i also had a noticeable bobble from the VTX blades,i guess since the VTX blades are alot more aerodynamically efficient than the Cyclones, that i had to turn down my rotor gain a lot along with pitch range and cyclic response...
As you've already experimented turning up the rotor gain which caused it to be worse,why not go the other way until it stops?
