I'd love to convert to electric and fly down the local park, but money wise it doesn't make a whole lot of sense.
Converting to electric from say a .46 motor, then going to a larger electric setup similar to stepping your .46 to a .60 costs $100's more if you buy decent gear, it just isn't worth it imho.

If the prices for electric gear ever became more realistic, I'd be first in line.
But for now I'd rather drop $35 bucks for a full tank of fuel and fly all day, then $400 bucks for a few batteries and have to wait to charge them AFTER they cool down.
