Thanks for the input. in response to Flipprob The 1320 gr. is "Fluggewicht mit RC-anlage" I Think that is an all up weight but the German thing is cofusing. Exeter , I understand there is still a danger factor with electric but at least the kids won't be messin with needle valves 1/2 inch from the prop or trying to finger start a glo engine ( yeah kids learn about chicken sticks the hard way). Still no one has been able to say what electric will preform like a .20 cu in glow engine
So we are looking at 46.5 oz, or approx. 3lbs...........hey look at that.....those were the numbers I already ran

Somewhere in the vicinity of 360-410 watts should do the trick.
Motor Options on a 3 cell 11.1 volt LiPo:
E-Flite Power 10, Himax 3516-1130 (on the low end of the watt range)
(you could go up to a 4cell 14.8 volt LiPo on these, but probably do not need to, benefit is more watts running less current=longer flight times, but you are forced to run a little smaller prop.)
Himax HC3522-0990 - 400-430watts
E-Flite Power 15 - 425watts
Axi 2820-12
As for a 0.20 electric conversion - it would be closer to the E-Flite Power 10 or HImax HC3516-1130 class - 350-375 watt motors
