The weather forecast on qualification day will be humid, colder maybe 28C, with possible rain.
What should I do, afm ?
Should I use 25% nitro ? C8TF glow plug ? Thank you for your racing tips.
I would not worry about changing Nitro % based on weather conditions. If anything I would maybe change the heat range of the plug. I only do this if the weather takes a big change from qualifing day to main day. On very humid days I might go to a slightly hotter plug. I normally use cold plugs; But with 16% fuel I use a Med heat plug just to give me a little better bottom end.
Pass you soon...
