Default V2 mini titan pitch pump issues

Hi Guys,
My heli cant do pitch pumps. Running HW 40A esc with align servos, beastx.
On the bench everything work find, in the air ok as well accept when I pump the
pitch, heli reacts very slowly to changes. Is it possible that 3A internal Bec
is insufficient to handle 3 servos at one go ? Btw thers no binding or tightness
of the linkages.

Thanks

What are your throttle curves and pitch curves?
If you can't do pitch pumps, could it be because it's bogging down?

Can't see the bec being the issue.

Idle up 80% flat curve. Pitch +- 10%. Its the same under normal throttle.
Pump pitch & the heli just takes it's own sweet time to react. So strange
