Ok...so I on't have to change anything on the engine to run less nitro? I heard it was reccomended to change the head spacing when going to 30% from 20% so I assumed it would be the same if going with less nitro as well. I want to try using 10-15% and see how that runs in my engines. I have been using MC-59 plugs as well for most of my engines. so I guess that won't change either.[8D]

Do you get your nitro, oil and methanol lacally or do you have to order it all online? how is shipping for these chemicals? are they considered hazardous materials? I would like to try and find them locally but I really don't know where to start looking for them?

Thanks again for all your help!
