RE: How to calculate line pull
Flyingagin
A good question. I went to the AMA web site and looked at the Membership Manual, page 4,for theSafety Code. The section for CL models is at the bottom. There is no line length statement in the Safety Code. Only that the Control system is to be inspected and given a pull test including the safety thong before flying. This is not all of the CL Safety rules, only the portion affecting Flyingagin's question paraphrazed! That is the rules I would think apply to non competition Control Lineflying.
PLEASE go to the AMA Web Site and read them completelyyourself!!!
As for Competition Flying my Taube is limited to 65 to 70 Foot lines as it weighs over 8 pounds.
