I would set it up at 3 degrees right and .5 degrees up. This will mean offsetting the engine 1/4" left and 1/16" down from center. However this is just a start to getting a good flying airplane. After setting the engine up at these angles, set the wing to .5 degrees positive. This is about 1/16" trailing edge low. the stab should be set at zero. Start with the CG at 40% from the leading edge at the root.
Activate a couple mixes. The first you want is about 1/16 to 3/32" of up elevator with full rudder deflection. The second is just a noticable amount of opposite aileron with rudder application. What these mixes are going to do is help eliminate the control cross coupling that all Extras seem to have. The other major thing is to get the ailerons set up correctly. Make sure you measure them and make sure you get exactly the same travel for both ailerons up and down. Don't assume the because the throws are the same in your TX that you are getting the same on the surface. Once that is set up the throw in about 8% differental.


Make absolutly sure the elevator is perfectly aligned with the stab. Take note on the maiden if you needed up or down trim. For down trim, move the CG forward opposite for up trim. This all should add up to a fairly nuetral flying airplane that will respond pure to control inputs and require little to no corrections on uplines.
