I have the most AWESOME set up and I love it!
Go to Sears and purchase this 4 volt Power Drill:

Then go buy a metric bit set from Ed's Tools:

That will give you a great set up. That is what I use for all my R/C builds. The drill is very light and fits in your hand nicely and does not have too much power that will strip screws, but just enough for all your R/C needs.
The bit set is the best and I swear by Ed's tools as would a lot of other members on here I am sure.
Good luck!
