one very important thing to add to this great post>>
don't go and buy the first brake cleaner u see. for our savys this "must" be "non-chlorinated" brake cleaner. any other type and u will melt everything plastic it touches!!!
the non-chlorinated type is plastic safe!

i am new to nitro and rc and with all the info being shared here i feel i have a lifetime of knowledge already..
