Hey bud,

A lot would have changed in that amount of time out of the game.

Check out the Australian for sale page, there may be something in there for you. https://www.rctech.net/forum/australia-sale-trade-103/

RB were good engines in their time, however are no longer made or supported with parts.
Novarossi, O.S. Max power, Gimar, Ilessi tuned engines are now the way to go.

As for servos try to match them to your reciever/transmitter.
