I think modern electric systems, just like good ARFs, have moved our hobby another step towards being a pure piloting endeavor. It's getting close to plug, trim and play now and we can devote our time to perfecting the piloting part of the art. That's even more important to us lower-class guys.
I've been learning about glow engines for more than 50 years and it's hard to see what I've learned become irrelevant, but it's sure nice to be able to just fly. I took a deep breath, opened my wallet and made the switch this year and I won't go back.
