It will vary slightly depending on how you want to fly the airplane. I like a scale aerobat that is very predictable and has minimal control cross couple. This setup requires that the engine thrustline and stab are set to zero but the wing has 1/2 to 3/4 degree positive. Then adjust the CG so that no elevator trim is required.

3D setup is a bit different as it uses the typical 0-0-0 setup and you run the CG back enough that no elevator trim is required. Flying will be a higher pilot workload but the airplane will do post stall maneuvers easier. This setup will have a pronounced down pitch with rudder application unless mixed out with your TX that will never 100% be eliminated.

As stated above. 30% back from the wing LE at the root is a good starting point.
