Hmmmmmmmmmm doesn't 10.5 pounds equal the same wing loading no matter what type engine it has in it?
I have yet to see a 10.5 lb glow takeoff with 0 fuel in it

So no it wouldnt
Figuring 20 oz of glow, then your 10.5 lb model at takeoff would need to weight in at about 9.25 lbs to be the same as the 10.5 e-model on takeoff.
