I learned how to fly on a Avistar RTF w/ OS .40 LA. It took me 3 months of Sundays during the summer of 2004 to solo...now, my friend, Sun_Kissed_Girl was learning how to fly on it, but she had to fly it at 50% rates (A while ago, I took out the 4VF and put in a 7CAP), otherwise it was too much. Then, I won a Nexstar RTF at a raffle and gave it to her (because I now fly 60 size sport planes), and it she said it flies much better, even at full rates. I flew it, and they are waaaaay sloooooow

. Brought it in for landing, and I could causually walk faster than it was flying in! I can now fly better than people that have been at this for 15+ years, and SKG is on her way to soloing.
Well, theres my life story on flying, so, I do think the Avistar is a litte hot to learn on (was for me!), but its not that much of a significant difference (after flying the Avistar, Nexstar, and a Xtra Easy II)
