So I got my new goods today and I have a question about mounting them in my airplane. I don't like the idea of small electronics flopping around while I'm doing manuvers so I would like to use some velcro to mount them to formers etc. Is this ok or do I need to use something like double sided foam tape?

Also, if I use a voltmeter with a simulated load of 250mA, is this enough to set the regulator?
