I have never had this happen before looking for some answers why this may happen. It was not over compression, the standard shims are being used. Fuel is good quality 16% nitro content.

For 16% Nitro you should have a 0.20mm shim only.
What plug you're using? Just could've been a faulty plug.
Plug fatigue can occur under high sustained RPM's, and this is where the plug stays shiny and the wire just fractures for no reason. When this happens it is usually not a carb. tuning or head clearance problem.
If you see the wire start to pull out of the hole this means that the engine is scavenging really hard and when this occurs the engine is making serious power.
Try a new plug and see if happens again.

It will happen when the compression is abnormal.
If that is a new engine,you need to adjust the shims to get the suitable compression.
If it is a old engine,and it works fine before. There must have some parts which cause the compression abnormal. Or you change the fuel lately....etc.

High Temps
Got to run today and no more flame out but the temps were a little high. Changed plug to a nova 5 from a os 7 and the response was beter, it had no power under 270 but it was not zinging at these temps, should i try shiming the clutch bell of the shoes and can a smaller track give high temps to

For 30% Nitro I'd use total 0.50mm shims, so if you say you have 1 alu, which is 0.30mm, the copper should be 0.20mm, but you must measure the copper one you have on, because there are thiner ones.
