Using velcro may result in weight savings compared to using machine screws to hold the electronics in place, at least if you are using steel screws. We switched from using #8-32 and #4-40 steel screws to the equivalent nylon screws a few years back and saved, as I recall somewhere on the order of one pound.

Industrial-strength, adhesive backed velcro should be available at your local hardware store. I usually get ours at Rona or Home Depot. It is also great for securing lexan body panels and many other parts that may need to be repositioned.
