First inhibit the control for the channel being used to drop the tank - controls are inhibited in Code 17. This is done so that the drop servo will only work as a result of pressing the snap button. For example, if Aux5/Ch10 is to be used for the drop servo, Inhibit AUX5 in the Code 17 function.

Next, set up a program mix, mixing the channel that is to drop the tank to itself (eg. AUX5 to AUX5 or Ch10 to Ch10). Touch "Page" and select the Snap Switch as the switch to activate the mix. Page back to the percentage display and while depressing the snap button, dial-in the percentage required to move the servo. If the servo travels in the wrong direction, touch "Turn" to reverse the direction of the mix.

When the switch is not depressed, the servo will probably be close to centered. If more travel is required, a precentage can be input with the snap switch not depressed, causing the servo to deflect in the opposite direction of the drop.

That should do it.
