Jack is right . . you can't bolt a glow motor to this airframe without strategic strengthening. An experienced builder can easily set this up for glow without much trouble at all . . .

An EP airframe is not that much different to a GP airframe, but they can go a little lighter on areas that would be normally weakened by glow vibration. When you know what areas these are, you can strengthen them . . . as they would have if they built it for glow. It all adds minimal weight done correctly. The rest of the airframe is subjected to the same forces with either power system, so generally the airframe is very adequate.
