The TT is kind of a fast little plane, there are some foam trainers out there with SAFE that fly really slow and would be really easy to learn on. Just google them. I cant remember the name of them right now...
If you want a really fun, inexpensive 3 channel that you can fly in the house, the UMX Vapor is a blast. Just a warning - cats see it as a bird and will leap to kill it.
You can fly it outside as well, but you need virtually NO wind whatsoever to fly it because it's so light.
Another fun one that we bought for my father last year for Christmas was the UMX Radian. It's got SAFE and is perhaps one of the easiest planes out there to put up into the air and glide with.
If you want more channels, the UMX Timber is a really nice little STOL plane, foam, with LED lights on the wingtips, that will take off in virtually nothing (I want to say 10 ft of runway or less?), and utilizes 5 channels, if you include the flaps (although you don't need to use them, but it makes it easier to slow that plane down and set it on the ground!)
Of course, those are all pretty much RTF/BNF planes, but they're still a lot of fun that are EASY to get up in the air and tool around with.
