GMP King Cobra

Development of the standard Cobra with the upgraded Pro-head (with no coning angle) and initial kits had natural aluminium side frames however, later model had black parts.  Most pivot points were upgraded with bearings instead of the plain bushes of the standard Cobra and the engine mount was made to suit a sixty size engine.  Tail boom and fins were the same as the competitor.
