I find that a Margarita and a little music keeps me working at the building table On a serious note, building an airplane is like some other projects. The last 10% of the build takes 90% of the time. My last build, a restored Taurus built from three planes(http://www.rcuniverse.com/forum/m_82...tm.htm#8323460), seemed to take more tequilla than normal(just kidding). That old saying of one step forward and two steps back did not come close. I was making three to four steps back for every step forward. But I said to myself that I would not let all the frustrations beat me. And they did not, she is now flying again.
