Hi Barry, I have ran the original RB5 recently too and it was competitive and decent.
Instructions you can download of the kyosho website

If you need any set ups search petit rc or give us a shout as there are plenty out there to get you going in the right direction.
Check the diffs all lubed and you have oil in the shocks and you should be on your way.
Good luck. I really enjoyed my run with the original RB5
