I'm looking at getting a Tensor as my first foamie. Whatever I get, I'm going with a brushless outrunner (either the e-flite or himax).

What is the Tensor actually designed for? Is it just better at knife edge flight or is it just a better building and sturdier version of the Ultimate? I'm wanting something to fly in a gym in the winter and something that will fly in light winds the rest of the time. I also want something that is sturdier than the shock-flyer. The Ultimate was my first choice but I figure that the Tensor is probably the better design.

Thanks,

chris
