Hi
Factory settings are fine, maybe a little less aileron because full aileron rolls very fast. With low power and full flaps it drops fast so reduce power when you are certain you have made the runway.
Try to land it smooth, because if you land hard you will bend the LG struts.
Factory CG es very nose heavy. Use the CG mentioned in this thread. I started with 90 mm in front of main wheel axle, which is a good starting point
The plane is rock solid and flies very well and it is predictable. I love it, so much that I bought a bigger one (Feibao)
Regards
Eduardo
