Neither! Try a ratcheting screw driver, you will mess up lots of screws using a cordless drill. I never use power tools to remove or install anything on light aircraft. Get a small tube of Boelube and put a dab on the threads of each screw, they will go in like butter and won't strip the threads off the first time they are installed into a new nutplate.

Wink my experience

ok, so I'm not a builder, just put 1,000's of screws in and out at annual etc.

when I was a kid, I removed the zillion screws from the typical Cessna's required at annual and other maintenance. Sometimes they would be frozen, underwing, and otherwise a real bear to remove.
in ONLY this instance, I would endorse an impact driver to remove them.

I've used a small 12v dewalt drill to remove and drive screws during maintenance of my RV, and as long as you turn the clutch down, so that it slips before you strip the screw head, and tighten the last few turns with a hand screwdriver, I can't see the problem with this.
If you overdrive and warp skins and strip nutplates, well, you'll learn your lesson pretty quickly!!!!

although kind of slow, I don't see why a good cordless screwdriver wouldn't take care of 90% of the tasks around the shop.

you don't really need the speed or weight and force of a big drill in most cases...and these little angle babies fit in places even a hand screwdriver won't!

My .02..

For tough, seized screws, the impact driver would probably work better for removal. I would not use it for installation.

Several of these are in hangars around my airport. Not super fast but great torque and battery life and won't break the bank. Buy 2.

Mike S showed me his stash of bee's wax for screw threads. Used it. Works great.

I use this one from Black and Decker. It allows to you "feel" the amount of torque that is applied. It is very intuitive to use. It allows you to put the correct amount of downward force so that the screw head does not strip and gently apply just enough torque to move the screw and control the last bit as it tightens up. It has a Gyro in it and senses your hand position.
