A fellow enthusiast….. I have an early model Austrak RT45 with MT500 motors which I have put new seals in but still have a problem with one motor which I have narrowed down to valve body (I think).
I am wanting to find somebody who can help me with parts/knowledge to fix.
I also have a later model chassy & some parts, not enough to rebuild but could be helpful to others.
Hope to hear from somebody!!!
