ok cool i did the pinch test at the track and it did get faster and it died in about 6 seconds i think i got the tune right if you ask me thanks for your help.
the loading up on idle you say is right that makes me feel compfortable with it thanks. least it didnt die earlyer than the 4-5 seconds mark so it must mean its not to lean which is the main thing im worried about so job done i say.thanks thanks thanks guys well done.

It all depends on the engine, air temperature, track conditions, driving style, fuel, glow plug, etc. so you can see there are many variables to consider. Therefore if it preforms well, exhibits a smoke trail on acceleration and doesn't load up or bog down then you're in the right range.
u r right on! my .21 RB WS7 1 runs around 250F +/- sometime i push it to 280F. this engine is sweet on idle... those deep sond is sooo nice. The problem is, it takes longer time to warm up on first run. temperture will hoover around 190F for 1st half tank and the buggys run some what sluggish but when the engine warms up to 200F it's power pack.

I agree not to tune on temperature but i strongly believe that the temperature reading serve as a guide as to how far you can push the engine before it Kaboom!
