Having flown YS for years and been a devoted YS guy and just switching to electric after the NATS this year I can give you some perspective of what I found. First off, THEY BOTH WORK and they BOTH WORK WELL. Both have tremendous power and torque. Being electric the torque is delivered even more instantaneously than the YS, which understanding how electric motors work didn't surprise me, but I was surprised at just how much torque is at your finger tips. The cost of glow fuel seems to be going up, and the cost of batteries is coming down. You can run the cheaper packs from hobby city and they work really well. Some of the other packs do have more power with them, but they all have more than you will ever need. I really like having zero vibration on the airframe which electric provides. It's also nice to not have to carry all the extra support equipment. I have 5 sets of packs, and if they are all charged, i can just go to the field with the 5 packs and fly 5 times and go home without bringing anything extra. Our field doesn't have power, so if I want to fly more, I have to bring my generator as well as my charge box. There is definitely less routine maintenance on the electric stuff although I still check everything regularly. One advantage to the YS is flight time though as you can fly up to twice as long on a flight (depending on tank size) as you can with a typical electric setup. Bottom line is they both work. With glow I think the investment is spread out over time, whereas electric you need to purchase packs, chargers and everything else up front, but in the end, if you take care of the batteries as described they will last a long time and your cost per flight keeps going down with the more cycles you can get from a pack.
