I have great respect for good engineering, I remember reports of this engine operating regularly well past the manufacturer's max. RPM's in a GAUI NX4 with no issues.
Great pity this engine is no longer available...
They were in general, GREAT engines: When they were still around, national Dutch championship 1/8th scale offroad buggy was won twice in a row with a GO engine.
I still have one (Rotorstar Apache branded) brandnew in box including the original cooling fan and the original Vortex heli muffler additional to the one I have been flying the past 7 years (identical set-up WRT fan and muffler).
I did however change the heatsink-eads for those of the MK II which are better in every respect.
