I learned on several 2 to 4 channel trainer type aircraft (yes, this implies multiple "incidents"

) and after getting reasonably competent with a 4 channel trainer I went to my Tiger 2. Excellent plane (hey it's not all that ugly

). I had some help from my instructor when I first started flying it but I think if you're competent with a 4-channel trainer you'd do fine with the Tiger. Veeerrry smooth flyer, very solid in the air. With a 2-stroke .46 you can do some pretty cool stuff with it (it's not a 3D machine though, but the .46 makes it quick and gives nice vertical performance). I would say the Tiger is a good "medium" plane between your average 4-channel trainer and something like an Extra 300. Also good for learning inverted maneuvers that you probably weren't able to do with your trainer.
Oh yeah, it's also *really* easy to land, at least the tricycle version is (have not tried the taildragger yet, going to convert mine to taildragger soon).
