Soooooooooo... with glow we used to go to the field with: Starter (1Kg); glow plug batt (few grams), fuel can (2 to 4 kgs) and pump for refueling (200 grams). With electrics we have to bring 1+battery pack (1Kg each), charger (1/2 a kg?), generator (at least 5kg), fuel for it... we can also just bring 4 battery pack for a normal flying day (leaving all the re-charging stuff at home).
Being so, I'll keep my 4S glow setting... I don't see where the "real" advantage is, specially if I consider the cost of the batteries.
Instead with gas we bring just the fuel can, right?
You can kill me but it's how I see it.
