I am some what attached to my glow planes the fuel it up and fly thing is great but I see alot of my club mates going elec and having a blast doing it.
it seems like the set up fee is about the same the lipos are getting lower in cost which is the real bottom line cost.
as for radios I would recomend getting a multi model memory programable radio so you can program and fly several models with one transmitter power doesn't matter glow or elec or servo size alot of guys fly there flat out foamy planes and there 1/5 scale planes on the same transmitter they sure have gotten better in the last 20+ years
