I see lots of people who do both electric and liquid fuels. Like this one guy who does electric 3D, electric gliders, EDF, glow aerobatics, gas aerobatics, turbines (I may have missed something).
A small percentile compared with numbers of those who don't.
Different power sources have their advantages in different applications
Logic has nothing to do with it. As the originator intended gauging by his footer, this is one of the half dozen questions which ALWAYS end up in a circular emotional argument. eg: electric vs gas, mode 1 vs mode 2, castor vs synthetic, etc. Sit back and watch the fireworks as merry go round goes around and around.
