I dunno.. I, for one, like to recommend traditional trainers to learn on.. even re-learn on. That "tame cat 40" is a pretty neat looking plane, and it says it's a trainer, but I put that in the same category as that PTS P51 Mustang that some talk about. They are pretty, but they are not real trainers. Ok... don't all pounce on me all at once now.. I'm offering my opinion and that's all.
I started with a Tower Trainer 40 and later, after on-off-on training sessions, switched over to a Nexstar Select RTF. It didn't take me long to solo with that plane, well, how long is long.. well, flying three flights a day with an instructor on a buddy box, about once a week was all I could do at the time becaus that was all the time I could devote to flying RC. It took me about two months of this sort of flying to solo, although the instructor told me I could have solo'ed much earlier.
Aaaaaanyway, you (the OP) said you had a Nexstar and it gave you trouble with the landing. Well, you never said you were doing this alone or not, but I suspect you were. If you had an instructor to work with, the very first thing he/she would have done is to check the plane to see that it was set up properly, then maiden it for you to get the trims right so that the plane flew great and landed like it was supposed to.
If you intend to do it alone again, highly discouraged by me and others, well that tame-cat 40 will be no different than the Nexstar was. It needs to be set up properly and trimmed for straight and level flight with hands off, at about mid throttle, and then you can go from there. But, this is probably best to be left to an instructor or an experienced pilot because there are some subtle parts of flying that plane that he/she will see and be able to point out before you attempt to fly it yourself.
Anyway, no matter what you do, best of luck with it.
