I've built two SE's, and tons of other planes. I'd have to say that the Sig SE's instructions were the best I've seen, and this is one of the easiest planes to put together. From your photo, I can see that you did leave the elevator joiner wire out. You will have to cut the hingesto both the elevtors and the rudder since you have to install the elevator's first! Also, some people might choose to leave off the stab supports on the tailfeathers. They're the wires that support the tail and some might leave them off to save weight. You MUST put these on. If not, you will snap your stabs. I learned this the hard way. Fortunately, I was able to land mine and repair the stabs and install those supports! Also, I agree with everybody else that the .40LA is weak for this plane. I have an OS .46FX on mine and it seems to be the perfect combo! I use an APC 10x6 prop. Matt
