As most of my models are electric powered, it has become second nature for me to become almost fanatical about weight reduction when I build. This practice still carries over when building glow powered.
And it's a great habit to get into!
Too many glow flyers have gotten use to stuffing a bigger engine in an overweight plane. While the larger engine will provide the "pull" necessary to get it in the air, the wing loading starts getting so high that the aircraft becomes a pig.
