Hi Steve, please use small caps when you type a post

First of all, the model must have a wingsweep function.

If your remote control unit has additional channels, you could assign it to "wingsweep" in the basic controls menu or to channel 25 in the advanced menu.

If your remote control unit has only 4 channels, some functions can also be controlled using the number-pad on your keyboard. For this Numlock must be activated. You have a total of 4 digital channels (operating like on/off switches) and 2 analog channels. You control the analog channels using the 2 (decrease) and 8 (increase) keys, and the 4 (decrease) and 6 (increase) keys. You can control the digital channels using the 1, 3, 7, and 9 keys. You can set up the digital channels with the functions retractable gear, smoke, tow hook, wheel brake and autorotation and the 2 analog channels for the flaps and wing sweep.
