RE: Your best building blunders! ...post em' here.
The other day, I took my Pawnee to the field for its first flight after its rebuild. I was ready to fuel it up and realized that I had to forgotten to install a fuel dot and with a tight cowling, no way to get to the fuel lines. It hit me that that's what I needed to get at the hobby shop, but got sidetracked. Since it would have been a pain to take of the cowling just to get to the fuel lines, I decided to fly my other plane. When I got home, I found a fuel dot, so take of the cowling and what did I find? I forgot to put any fuel lines on the fuel tank[:@]!! Glad that I didn't pull the cowl off at the field - the peanut gallery would have eaten me up!! That's what happens when you working on three planes at that the same time[X(]
I won't go into how many times I done stupid CA tricks in over 25 years of balas related modeling.
