Elevator control: Pull-pull vs push rod

[s.vannostrand at kodak.com]

Dan is the man!   I use the same pull-pull on elevator and rudder,but I 
use 30# coated steel fishing leader.  THat's 30# for each elevator half. 
It's lighter, easier to bend and work with, and seems reliable.  The wire 
exit guides are a must on a carbon fiber Aries fuse. 

For safety, I've seen several people put 4 eyelets at the servo end (2 at 
each arm) so that each elevator half has a dedicated wire.  Then, if a 
wire breaks, the other elevator half keeps working.  I've seen a Prophecy 
fly around and land after losing an elevator half.  I guess we really 
don't need a full elevator for basic flight.  This is a good idea, but the 
extra 2 eyelet linkages are a small weight penalty and its harder to wire 
up.  I've never done it this way (I use one looped wire for both halves), 
but after seeing Wayne lose his plane because of a bad crimp, I'm 
considering changing.
