                             Questions on fuel
    
    
    Hi, my name is Art I am new to RC Notes.
    
     1. Just got off the phone with Tower Hobbies and I'm confused about
    the difference between sport and premium fuel? The answer I got
    from them was their is more nitro in premium than sport fuel.
    
     2. Now logic tells me that if it is rated 10% it shouldn't make
    a difference in how it burns, unless the other ingredients are taken
    into concederation.
    
     3. Would be very thankfull to all for any understanding of this.

    The only thing I can say is that with some "sport" fuels (I don't
    know about towers) they use a reclaimed nitro. This is nitro that
    has been used in some other chemical process and then seperated.
    They say that they only get nitro from this process?

    	The Tower catalog states that the premium fule has a greater
    concentration of lubricants and is all synthetic oil. The sport
    fuel uses castor and synthetic.

    I'll tell Ya, I sell a fuel from Penn. called S&W. You'll see it
    advertized in Flying Models. When I order the only item that changes
    the price per gallon is "Nitro" content. 100% castor,100% synthetic,
    15-18-20-22% oil. Whatever ya want. It's all the same price. 10%
    Nitro,12.5% nitro,20% nitro. They all cost different prices. The
    NITRO is the costly item in our fuel.

881.5Hazardous substances in fuelGIDDAY::CHADDSun Jan 21 1990 19:0227
On the subject of fuel mixture's I would like to raise the question of
hazardous substances that are used by various groups in fuel. While I don't like
to point fingers at any group it appears to be the biggest risk takers are the
Old Timer movement. They are experimenting with some "exotic" mixture's for 
economy not performance.

I recently read an article where the author was dismayed that  people were
still asking where they get such substances as nitro benzene, zylene, and
paraledhyde to name a few. The hazards nature of these substances have been
well documented. The risk is not only to the used but also any bystander or
helper that inhales the fumes. The same author also reported he had recently
had surgery for cancer and the surgeon while he could not guarantee the cause to
be contact with these "exotic" substances in his early modelling career
indicated it was a probable cause. 

In Australia Tetra-nitro-methane, nitro benzene and hydrazine are banned. I am 
interested to see comment on:-

	1. What substances are banned in other countries.
	2. What other substances should be avoided in fuel.

It is possible for some quite safe substances in there raw unburnt/mixed state 
to become toxic or dangerous as a fuel. Any person in these notes with 
chemists knowledge may like to explain (simply) what is happening with things 
such as trioxides etc.
