Wycome Air Centre is definitely run as a separate entity and was never a "Cabair School of Flying". I think the rest of Cabair were trying to use WAC as a model for how things should be done.
I think the issues at Cabair generally came about because the new investors have spent the majority of the last 12 months arguing between themselves and not in keeping an eye on where the business was going.
Problems will always come about when people invest in aviation companies without having a real idea about the business.
