yes correct or not...... I guess I call it glow fuel, as there are many different mix's of nitro, castrol,synthetic ,and I am sure we don't even want to start including home brew, and ethanol, and glow motors running gasoline and gasoline motors running glow !! ha ha
Ok I will give you MY personal preferences...
Glow, messy,expensive, and I can't tune an engine to save my life ! I realize that s blasphemy
Gasoline, once set they run pretty reliable, conversions are interesting, they power the size of planes I prefer lately.
Electric, love them..but I only fly small electrics with interchangeable batteries mainly , They are clean, quiet, small, good run times. Electrics can do anything the others can nowadays, if you setup right. I prefer them for small trunk sized planes.
