MK Dual Elavator Bellcrank & Pushrod?

[John Ferrell]

Be very careful about alignment. An extra bushing on the shaft can cause a lock up under vibration.
A foam rubber damper is safer. It can be as simple as a wad of foam or as complicated as another bulkhead.

  I've mounted the bellcrank and will use Central's carbon fiber push rod.  The pushrod length from servo to crank is about 28".  

   

  Is it necessary to install a support of the rod  halfway down the fuselage to prevent flexing.  And if so does anyone have a simple way of doing this inside a fiberglass fuselage?

   

  TIA
