RE: From NexStar to Four Star
Just like everyone else noted, have someone else fly with you for the first few flights to trim it out and to show you how to take off and land. I went from a NexStar to a Cessna 182 then to a FourStar 40. The FourStar was easier to fly than the Cessna in my opinion.
Check out my build thread if you are going to build yours or if you just want to read the report of my FourStar 40 maiden flight here it is:

Good luck!
