Hi Bud
Great find and well done you, after my first RC car (Tamiya Hotshot), my first serious club racer was a brand new PB Maxima (which is essentially a modified updated mustang) loved racing that car and great handling but let down by its plastic parts. Many times I lost the front one way bearing drives because the plasric ball joints popped out, In addition to keeping having to strip the chassis down because the belt had slipped off due to the tensioner failing (metal screw in plastic housing).
Eventually bought a new Yokomo YZ870c (one of the first in the country) and raced with that (still have that car), but would've loved to still have that Maxima.
