First of all Thank you very much all you posted in here, what I concluded is that, naturally excessive use of nitro or it's higher percentage may cause an engine damage, which ofcourse nobody would like that. Nitro is not harmful, its an additive to add extra power, extra RPM as well as easy engine tunning.

I'd like to ask Piper Chuck, from which country your mother in law belongs and which is her first language? spanish?, as my first language is not english its Urdu and my wife's first language is English. People ask me why my wife can't speak my language, so I say that I don't have problem talking to her in english so thatswhy she never learned where as my son 6 1/2 speaks my language perfectly with few masculine & feminine mistakes as he is from my wife's first husband and I love him as my own son. My wife still gets amazed how he speaks her husband's language main reason, he interacts with kids a lot, his whole life is revolving around playing lol .

Well, as far as Im here in Karachi, Pakistan, I'm using that FAI fuel 80/20, upon arriving to USA I'd be using 15% to 20% Nitro. Thanks to all for your replies. If anyone likes to add further clarification to it, It would increase my info more.
