I should have been more specific. Many modelers still prefer
combustion engines to power their models. They are powered, contrary
to popular belief, mainly by methanol. Nitromethane can be added to
improve certain properties of the fuel. I use 5% on the large engines,
and 15% on the smaller ones. Very few modelers use more than 40%
nitro. There's also 15-20% oil in the mix.

What I should have said, was that no other type of battery is
considered when choosing batteries for electrically powered models.
Even that would not be entirely accurate. Some modelers choose the
LiFePo4 batteries. They have less energy density than LiPo, but are
safer and more tolerant to abuse, such as over- and under charging.
