We studied the planes and read the manual a few times and feel comfortable. We are starting slow on the wings, don't really want to mess the spars up.
We started by machine countersinking the tank skin nutplate mounting holes. We are still betting organized, and it took me about a hour. I used my rechargable electric drill. I find it much easier to make smooth accurate countersinks. Slower RPM and less chance of chattering. Works for me, and the holes turned out nice.
