Cheers mad_genius.

I cranked her up again today. Took your advice; this time she ran ALOT better.

And oh the power! I was afraid that the tether may rip the entire tail assembly off.

I'm still concerned (less but still concerned) about running it 'too' lean. The manual raves on in bold capitals about not running it too lean. I was wondering. What are the things too look for to know whether your engine is running too lean?

Hey there,

great to see another Aussie joining the addiction, or rather the hobby As for if it running to lean, the engine will run hotter the normal(but that is sometimes hard to tell). It will also most likely cut out at full throttle due to fuel starvation. There will be an absence of fuel spitting out the exhaust and no smoke.

One thing to remember is that we have altitude to account for. Engines do lean out some once you go up due to pressure changes so it is always good to be a little rich without being too rich if you get me. All my engines have a decent trail of smoke blowing once in the air.

Hope that helps,
