RE: Welcome to Club SAITO !
Funtanas:
Read the reports on both the 40 and 90 on the user reviews section. The 90 is a bit more docile than the 40. I had the 40 and loved it, after I got over the twitchies. My 40 had a FA91 in it. A friend at the field has a 90 with a Saito 150 and let me fly it. I would get a 90 before another 40.
