My first electric to glow conversion…

I'm converting a scratch-built 60”ws Decathlon from electric to glow. Why? Because I had nice running OS 46 and I didn’t want to spend the $$ for an electric motor and speed controller. Assuming no defects, do the electric airframes hold up under the vibrations of glow engines? Am I asking for a structural failure here? With its light weight, I want to use this plane as a slow flyer – no acrobatics.

Thanks
