Danny,
How can i give an airplane three flap positions(up, partial,and down) using a switch on the 8103 tx.?

You will set the LAND switch position in the landing menu. To set the other 2 positions, begin by going to the flap pot function, and setting it to 100% flap pot full. Then set up a flap to flap mix in program mix 4, press select until the arrow points at Offset. Rotate the flap pot to the full negative mark. Then press clear to store an offset. Then if you want to inhibit the pot, return to the flap pot function and press clear until you have inhibited it. Then go back to the mix, press select until the arrow points at SW. Press the + key until it says ELE>F. Then press select until the arrow points at the rate adjustments. Move the flap switch to the up position and enter in a percentage. Then recenter your servos with the flap switch in the up position. Adjust the percentage in the mix such that you get the amount of flaps you want moving from the up position to the center position.

You could set the flap pot to just be a trim pot so it does not have a large effect, or inhibit in in the flap pot function. You can set elevator compensation in the landing menu, or through a flap to elevator mix.
