Yeah, I would agree with all of you who said they fly uh different. The two I have had fly or perhaps flew is a better word, greatly. takes getting used to. With my flatana I could pull the old "bank and yank" to turn and it worked fine, still needed a little rudder but not much. The biplanes roll 90 degrees and keep right on going.I have really started to like them, just ordered an Ultrafly Radix tonight to replace my smashed EPP bi-plane(gave itself to science i geuss, testing a vertical thrust vectoring thing I'm working on)wait till you see that system when its all worked out. I did standing loops so fast and hard something let go and it spiraled into a tree, then after getting shhok out and falling it was a pile of foam. gotta tame the system down alot. anyway, I'd say go for a biplane if you like the tensor, its kinda the same deal as the radix i ordered but a bit tuffer, then again I have gotten the 3-D thing down really really well, so crashing is few and far between, though a few bumps and bruises never go away it will happen sooner or later...
