Flight configuration in auto Aviao vtol

hello!!! I am having problems with my VTOL, it is not flying very well, every time it activates the multirotor, it seems that it is not maintaining a speed to remain stable in Airplane flight and it is not following the programmed lines in the mission very well, can someone analyze my log and help me fix it?

flying in Airplane mode, the engines turn off, but when passing a wp, it seems that the rear engine slows down and the multirotor is activated, as if the q_assistant came into action, it seems that it is not obeying the cruise speed that I programmed…. I’m using a custom v-tail template. when I fly in FBWA mode, it flies very well, but in auto mode it is not so good.
