Setup Paraglide
The basic paraglide control uses two servos, each of them pulling its own side of the brake lines (the rearmost lines). In the neutral position, the servo levers ("hands") are both in the upmost position. When turning, only one of the servos should pull its brake lines, i.e. the hand is going down. This is unlike the V-Tail or Elevon mix, where both servos move in the opposite directions during turns. When braking, both hands should go down simultaneously.
The main challenge with setting this up is to use the full range of the servo travel, instead of just half range. In other words, we want the servos to be at one end of its travel when the sticks are in the neutral position.
There are two different ways how to pilot the paraglide:
-
Aileron-elevator control, where the aileron direction controls the left servo only when the stick is moved to the left, and the right servo only when the stick moved to the right. In addition to that, pulling the elevator direction pulls both servos simultaneously, and pushing the elevator does nothing.
-
Full-scale control, where the left stick from the neutral to the outwards left position controls the full travel of the left servo, the right stick from the middle to the outwards right position controls the right servo, inwards movement of those sticks does nothing, and also the elevator direction movement does nothing. This simulates how full-scale paraglider pilots control the brake lines.
So far I did not find a good way how to set up the first mode with full servo travel using only three available mixes of FS-i6. So I will describe how to set up the second (full-scale like) type control:
I presume Mode 2 (throttle+rudder on the left stick) here. Plug the left servo
to Ch4 and the right servo to Ch1 of your receiver. Then set up the
following mixes in order to map half of the stick travel to the full travel
of the servos:
Key → Mix → Mix #1
Mix is On
Master Ch1
Slave Ch1
Pos. mix 100%
Neg. mix 0%
Offset -50%
Key → Mix → Mix #2
Mix is On
Master Ch4
Slave Ch4
Pos. mix 0%
Neg. mix 100%
Offset +50%
Some paraglides have additional servo(s) to control the A-lines (front lines). Also, some pilots use potentiometer for controlling the neutral position of the main servos, allowing them to fly in a slightly braked mode. So far I did not configure any of these features.
