If you are doing a predator stye plane then electric is for low noise. Nitro is noisy. A nitro engine shouldn't put any more stress on the airframe than electric, thrust is thrust. Not sure if gas or electric is heavier any more with the new lighter lithium batteries. Back in the day batteries were heavy. In most of the online videos I see of larger electric planes they fly like they look heavy to me.
