Hi Rob
Started with rubber power a while back - around 40 years, then diesel / glow CL, eventually into RC, both glow and gliders around 1979. Flew pattern, scale, open and mini (equiv to HLG) gliders, mostly sport, some comps.
Also dabbled on the fringes of indoor CO2 / ruber scale!
Gave up gliders - pointless and boring. Gave up comps - far too much of unobtainable spare time needed in all directions. I look back on my little forays into scale comps with great affection. Through all that, my big love was designing my own sports glow powered models - always small-ish in size, usually pretty fast, almost inevitably aerobatic.
Around 1985, built my first electric. It wasn't a snoarer and you could swap the pack without taking the model apart. That must have had a long lasting effect on me!
Really looked at electrics for sports flying around 1996, after my first trip to KRC. After seeing Keith Shaw fly his 20 cell, 65" semiscale Me 35 at KRC 97, I decided that I wanted something like it. Shortly afterwards, the dust got thicker on the glow models, and I haven't flown wet power since maybe 1998. Can now get what performance I need out of an electric. It is a greater challenge to do so, from buying suitable stuff, to assembling a model that is light enough to offset that battery, to flying without an almost endless amount of power on tap all the time.
If I wanted a glow model, I'd go buy one. Okay, my wife would roll her eyes at the funny smells in the house once more, but she's very tolerant of my funny little hobby. But I don't need the oil, smell and fuss, so why bother? I've flown at a few mixed fuel fields, no seems to mind - or even notice - my electrics. One or two have gone off all thoughtful.
Heck, it's a big world. It can stand the odd guy who, faced with the noise restraints threatening our hobby, flies a Zenoah 62 with no muffler (maybe but not for long though

) That means all in between are fine.
