Whats the flight pack and fuel weigh?
The motor mount or beams and epoxy and enforcements?
On these little guys 3 ounces make a whopping difference.The glow should fly and perform,but I'd bet that a proper E set up would kick its Butt in every way.
Its cool to see these minis in glow though,years ago,they would not have worked as well in such a tiny airframe.
I used to have an OS15 in a Pylon Mustang,that thing ripped,good times.
