I highly recommend the World Models Super Sports 40. I flew a Hanger 9 Alpha trainer for about 6 months or so and moved on to this at the recommendation of several people. If you can land a trainer consistently you'll be able to land the SS 40 with no sweat. I have dual rate throws set on my JR 662 which allows me to switch between 65% (or whatever I set it to) and 100% or more if I choose. At 65% it flys a lot like a trainer but is still a little more responsive. At 100 + % it is a blast ! ! I highly recommend it if you are comfortable w/the trainer.
