Can any body help me? something about CruiseAder Claire

This type of plane has four motors, the two rear motors rotate horizontal in FW mode as well as the front motors, is that true?
Or the rear motors remain vertical, only front motors rotate horizontal like E-flite Convergence?
The document does not make it clear.

I suggest going to the Slack forum to try to contact the Maintainer: Samay Siga. Maybe someone in the dev team can direct you to the right source.

Good luck.
