I love the Taurus and I think it is the BEST aerobatic plane for the pattern sequence in use in the early sixties and for REED systems. If you do not consider flying reed in an old pattern schedule,m then the taurus is not for you. Even if the OS 55 will provide twice as much the power of the old VECO 45, nevertheless the design is not a good one for Proportional systems and it is not at ease with inverted maneuvers, as well as rotation around the X axis.
I'm building one right now, but I plan to use a VECO 50 and a modern "REED" system...
