Tuned up A10 motor dumped into Gold Star chassis resulted in a collector’s piece that can’t make it against minor Jap’s. Excess vibration and an engine that fell apart if used to the limit for an excessive length of time. However, there are some stock A10’s in Goldie chassis that make for useful tackle with upgraded electrics. These have all of the pose, style and none of the inherent hassles. Stock RGS’s are too expensive but the fake stuff can be bought cheaply.
