U Can Do 3D
Tailwheel,
I believe I mentioned it at some point. I hate tailwheels which has a direct connection and possibility of transfer of force to rudder. I like the Klett tailwheels, but have been told they are not made any more, so I have a Du-Bro on mine.
Engine,
I just went from a YS120NC to a YS120SC, which has made the plane balistic. My uplines from hover is faster than some planes' down lines ha ha, and my tail is still attached. YS120 is what I say for power, or an OS160FX would be fun as well.
