Default Fuel Percentages

People,

I'm just trying to figure out what the optimum nitro/oil percentages for the not-so-sunny UK are. Running an 18ss with an O'Donnell 077 in fairly damp conditions (most of the time). Generally fairly low baro pressure (less than 29.92 or 1013mb) and purely used for bashing off road.

And if I could be so bold as to sneak in an extra - expecting delivery of Hellfire K4.6 High Output in January... Any idea what will be opti percentages given the above conditions?

Sorry if this sounds thick - still trying to figure out what it all means!

Okay..... so not much of a response! How about a different tact - I assume different plugs work better or worse with different fuels and different weather conditions. Given the previously posted weather (damp, low pressure) can anybody recommend an optimum setup?

Please?

Anyone??

I'll get my coat.

wat is your question?

generally racers use 10% oil and either 25% or 20% nitro. i prefer hotter plugs as it helps it idle better.

Thanks Doomah

I guess the question is whether or not people use differing fuel percentages or plug types with different weather conditions/barometric pressures to give optimum performance. Hotter plugs for better idling is a start.

People spend vast amounts of money on their engines and the tiniest performance enhancing techniques, and spend hours trying to fine tune the little suckers and this just seemed like another area to look at. I don't race, I build and bash for fun. But in the colder and wetter days, I like to look at ways I can improve the overall package. As there are so many different fuels etc out there, I wondered if it was a feature in racing.

ok, here is a link that will help you choose what plug you run depending on what %nitro u use and the weather temp.... a 5plug (hot) seems the go for you.... the od77 is a hot/warm plug, so your in the ball park.
