I am getting back into RC planes after 20 years. My daughter is old enough to have taken an interest. Many things have changed, glues, RTF planes, etc. One question I had was about fuel storage. We are using 10% nitro fuel. Everyone seems to be dispensing from the plastic gallons the product is sold in....I was alway told (20 yrs ago) to transfer the fuel to a metal can. The idea I thought had to do with sunlight exposure??? I see Tower sells a non-transparent plastic gallon....Is it a problem to use the 'factory' clear bottle on my field box....???? Thanks for any help
