Not the same size, but I flew a 50 size plane converted to electric by Mr Arun at Sholavaram last Sunday. Hadn't flown electric conversions of such size so far, the feel is completely different ! I have to also admit that glow/gas feels more at home at this size (could be just a personal feeling/preference)
I believe Sai/RCForAll supplied the motor and the ESC.
With the (earlier?) concerns about glow fuel, it is no wonder people were considering electric conversions even on their bigger models.
