You will likely spend more hours building than flying. Take the time to set up your work area and invest what you need to make the build enjoyable. Just a couple of years ago would have said that a good high speed (3,000+ RPM) pneumatic drill was essential. Today's, small lithium battery drills are now good enough. Get a small light weight one, The 12 volt size seems about right. Must have multiple batteries so can swap out to recharge while you keep working. Select one that has both high and low speed range with the high as high as you can find, about 1,800 RPM seems about top for battery powered drills. Small and light weight allows working in tighter spots, but more important, lessens hand and arm fatigue that causes errors. The good battery operated drills have one advantage over low cost pneumatic drills, the soft slow start is less liable to result in drill bits walking. (The good pneumatic drill like Sioux do have a trigger that allows for soft slow starts, but can buy a couple of small good quality lithium battery drills for the price of one of those.)
