RE: Brio - Glow to Electric
Kelly, many Brios, maybe even most of them, were heavy to begin with. I remember buying the last couple of them and the fuses alone weighed 46 ounces (canopy and chin included). My finished model (my design wings and stabs) sports a gas engine and weighs in at 11# 5 ozs which includes 5 ounces of nose weight. The wing area is 1110 square inches and the model flies very well since wing loading is reasonable
It appears that you're not affraid to tackle the challenge so let me suggest that you build another set of wings with plus 100 squares in area. Try to get the weight the same or slightly lower if you can. It won't reduce flying weight much but will make the model feel lighter on the wing
