Basic, old school works just as well as gadgets. I'm a tech geek, but you may find a lot of that stuff stays in the drawer. The one gadget I find handy is a Robart incidence meter, but still not a must-have item. When measuring CG, I put some trim tape (or a magic marker) on the manufacturer's recommended CG, then have a ready reference during the final build phase. <div>

He hadn't checked the Cg, so I downloaded the manual on my phone and we used a tape measure to mark the spot on each wing. It was assembled, so another member and I used our Mk1-A fingertips to lift the plane. It was spot-on, which was reassuring. After all that, we had to wait an hour to maiden it. Seems he forgot to fully charge the battery lol. </div><div>Good luck, have fun and Happy New Year!</div>
