Collective Spring UPDATED – August 27, 2009

To prevent an unexpected movement of the collective in the event of failure of the spring or cable , the spring and cable provided with a Kit should be doubled. If you are using the cable and spring provided, please contact us for a second cable and spring to install on your helicopter to provide redundancy.

If your helicopter is constructed with another system, please be certain that it provides redundancy in the event of failure of the system being used.

While there have been no accidents attributed to this cause, such an event may prove unsettling to a novice pilot.
