its all common knowledge up for grabs on the interwebs or if you are an experienced nitro head you just know things
if rc heads lack the instruments to do proper research or lack the lust to do it, only then i can imagine a nitro hotline being the last resort paid method for help hahaha
and again this common knowledge can be gained by anyone if they put the effort and time in it hahaha, its just a matter of are you going to do it? or not
Just reminiscing about hobbico i loved it
