I have half-heartedly investigated this aspect of the hobby (glo vs elec) & concluded that in order to get the same performance in similar airframes (not the normal elec "flimsies"), you have to spend a LOT of money on electric models.

It is reasonably cheap (similar to glo) to do electric with light and fragile airframes (also, usually smaller airframes). However, size & substance really cost big bucks in the "live better electrically" world. So much so that I'm not going there until the price comes down to believable levels for power to match the glo models.
