REFLECTOR: Elevator Trim Spring

[Ron Brown]

Morning John,

No, lets try again.

The objective is to move the actuator forward a bit which provides more up 
(elevator down) trim.  (That is if you have a problem with not enough "up" 
trim when in cruise configuration, only one person in front seats.  This 
solution allowed me to not only cruise without pushing forward on the stick, 
but also to trim for a 500 fpm descent with a slight reduction in power).

To move the actuator forward, you will need to cut the canard attach bracket 
so that the hole is gone.  Now drill a new hole that is 1/4" to 3/8" forward 
of where the old hole was.

By the way, the bracket shown in the new on-line manual is different from my 
1999 kit.  The new bracket (Long Bracket VAB-02) shown on page 10-8 of the 
online manuals is shorter than mine.  What ever bracket you have, the 
objective is to move the forward part of the actuator about 3/8" toward the 
nose of the plane.
