Title: ...Thread's...
Post by: Bootlegger on October 31, 2009, 07:12:12 AM

  Which is better, and why??  Rolled thread's or cut with a die cut thread's?  I am thinking about using a threaded pushrod..
     Thanks, D>K

At the sizes we use and the strength needed, I don't think it makes any difference.

Rolled is stronger !

I have found any threaded rod to be to flexable. Use carbon tubes with threaded inserts to connect to the ball links

I use 4-40 threaded rod and ball link on the bellcrank end and metal quick link on the flap end. For the flap to elevator I use short pieces of 4-40 or 2-56 glued into an appropriate dia. carbon tube. Quick links on each end. One end with thread locker or Z bend one end and link the other.

Check out the CLC(Control Line Central) site which is Jim Snelson.  He has most of the Tom Morris stuff.  Also any decent hobby shop should have the threaded rods in both sizes with the quick links and ball links as separate peices.

Bootlegger John gave the answer but I also use one's that are in the RC car parts at almost any hobby shop. The smaller lighter ones are OK for planes up to two pounds.
