Default SU27 Control Surface Setup for ARF

I just received a [link=http://www.nitroplanes.com/4-ch-russian-knight-su-27-.html]Nitro Planes SU-27 Flanker ARF [/link] yesterday and laid parts out to see what is entailed in assembly. Looks pretty straight forth, however, the manual seems more specific to an RTF which is already set up to fly meaning Rx is included with the plane and already wired and installed in the fuselage. There is also a radio Tx included with the RTF version that is not included with the ARF version. I opted for the ARF verison in order to use my own radio which I am comfortable with which includes many key features such as dual rates and exponential controls not customarily seen on the RTF radios. In laying out the wiring, it is not difficult to figure out which wires connect to which channels on my Rx unit but labelling the wires would not be a bad idea especially for the novice.

As for control throw limits and main reason for my post, there is nothing in the manual anywhere to specify what the throws are normally set to for starting out and for aerodynamics. For anyone that flies, we all know that there can be a huge difference in controlability based on where the control surface deflection is set to start. I can only assume that 3/16 deflection up and down on low rate should suffice with higher deflection for high rate but a diagram or notes would be a big help and takes nothign for the company making this model to include.

It appears that there is no rudder control for this plane aside from the steerign front wheel and I also assume that there is no mixing of channels as in flapperon or elevon. If there is any requirement or recommednation that I might have overlooked, please let me know.
