OK here goes. The TQ can accept all the bits from a hyper PRO. A lot of the Hyper PBS bits will not fit however. The difference is in the type of steering/suspension set up. The PBS is pivot ball suspension and the TQ and pro is C-hub. you could however change the whole front and rear ends and change one to the other. Choose the type you like and buy that one. C-hub steers sharper but is less adjustable and vice versa. One is not better than the other just different. Some parts however are the same for both but tend not to belong to the front or rear sections.
Hope this helps
