In response to post #517, regarding the strong pitch to the belly, you "could" try increasing the wing incidence. If your really observant, a 1/8" spacer placed between the wing TE and the wing saddle will effect a change. If your not so observant, make it a 1/4" spacer just for "experiment" sake. 1/4" should effect a serious change, as I'm sure it is several degrees. However, be prepared for the plane to pitch up when you take off, because it will need down trim of the elevator.

OR, use the mix function on your radio. Make rudder the master, and elevator the slave. Add a percentage of elevator that goes the correct direction for your radio. Check the other side of rudder.

If you have the Futaba 9C do the following: Open the mix menu and make the proper selections. Leave the menu open. Predetermine which direction of "dial" give the proper elevator mix response. Fly the plane in K.E. and use the dial to induce the correct mix. Fly many passess, and ensure it is the proper amount. This saves many landings and small changes. I do this with my pattern plane. The mix menus are easy to access in flight.
