Carbon rods?

[Ed Deaver]

Hey Bill.  I have used these on the past 3 planes, including my Oly Medal 
test fighted Sun.  I use a Dave Brown  shaft about 4 inches long to attach 
to the servo.  I used the dual output attachment to run the CF through.  
Then, wrapped thread and thin CA around the inside of the attachment, Ca 
generously on the outside of the attachment and the strength has been great. 
  My Oly probably has at least 1000 flights on it without a glitch.  Attach 
the attachement to the DB shaft with thin CA again, and for peace of mind, 
put heat shrink aroung this end.  Used 4-40 and normal attachment meathods 
for the other end, to the servo.

A ladder or series of support pieces are needed in the fuse.  On the Medal I 
put one rear, one forward close tot he servo, and one in the middle, making 
sure the cf cannot flex.  This is an extremely simple set up, light, and has 
served me well.  The cf is flexible enough it will bend slightly as you 
install the system.  I can take picts and e-mail you personally if it would 
be of help.
