I am used to building and I have pretty good results. I am sure I could correct the Focus Sport well, but I wouldn't be happy with the idea of paying for an ARF and getting a bad kit. I have read and saved Troy Newman's complete build thread. That is awesome and is the reason that I would consider the Focus Sport. I am very familiar with the linkage setup that he is talking about. I just set up my new SIG Somethin' Extra like that. You can see my new "Flight Streak" aka Sumpthin Extra on the kit forum under "another somethin' extra build. It really flies nice. I even tried to fly it with gloves on in our 14 degree temps today. I had to pull my right glove off though. God this weather is inhuman!!
