I definitely don't want to dampen your enthusiasm, but I do have to agree with Spitfire here. There is more to and advanced plane that having the ability to fly it. Just like you improve your flying skills by moving up increasingly more advanced planes, you also improve your building skills by working on different planes as you advance. A lot of times on more advanced planes they will assume that you know how to certain things (like locating the center of the firewall for your motor mount). My advice here would be one of two different things. First, put the Sukhoi aside until you get some more experience in both flying and assembling. Second, if you must do the Sukhoi next you may want to find somebody locally that can show you how to properly set up the plane. I know that this isn't the advice that you wanted to hear, but sometimes it's the best advice to give in cases like this. I would much rather see you have great success with this plane being flown later on down the road than see it turn into a pile of splinters in the very near future.

Hope this helps
