12.1 Removing the throttle spring

The neutral position of the throttle stick is in the centre (zero position). A spring ensures
that the stick returns to the neutral position when you let go of it.
This design offers a lot of advantages to inexperienced pilots but may be impractical for
more experienced ones. For this reason, pilots can remove the throttle spring by which the
throttle's zero position is shifted from the centre to the bottom stop. In other words, the zero
position is reached by moving the stick to the bottom. Follow the instructions.
Avoid electromagnetic discharge! Discharge yourself
before touching electronic components.
