Forgive me for my laymen knowledge, but I have a question about drilling. I bought a Kadet LT-40, and as I have had no experience building R/C planes, I was wondering if there was any reason not to use an electric drill. I ask because I have seen pictures of other planes being assembled using hand drills, but other instructions say electric or hand, as for mine, it says "Drill", so please let me know if theres any reason not to use an electric drill to do the drilling. Thanks.

No problem.

I agree with MinnFlyer and have used my electric drill in many cases. The one thing you need to be careful with is the weight and power of the drill. I find that I have more control with a small hand drill when the holes are small and in softer material. Sometimes a power drill tends to grip the side of the wood and will pull it in rather quickly. Otherwise, drill away.

hookedonrc defines the problem well. What you can do is take a scrap piece of plywood and place it over the balsa you plan to drill. You'll need to register it somehow. For example, draw centerlines on the balsa and then on the plywood and line them up. The plywood will support the drill when you start it. Of course you'll have to clamp the ply to the balsa so it doesn't spin off.

I just use my dewalt cordless or a drill press if I want it perfectly striaght.
