Iam abit worried about if my drag/antidrag wires will be strong enough.
The Acro Sport plans calls for AN 703AC wires ( Mc.Whyte or Bruntons ). As everybody knows, these wires are extremely expensive, so I made my own wires from 3/16"stainless steel using a die and a guide to make the threads.
Now the problem: The Mc. Whyte wires is made from stainless steel type 316 which have a tensile strengh of 150.000 PSI and cold worked to 215.000 PSI. This is a lot more than the 85.000 PSI tensile strengh of the 304 stainless rods that I have used. Perhaps I should have used 4130N rods which is a little stronger with 90.000PSI, but stillfar fromthe MC. Whytes.
Question: Do I have to worry? Are there any out there who have experience flying with homemade wires. Or what wires doSkybolt, Starduster and Pitts builders use. ?
I am a little reluctant to change the wires, as I have the leading edges on the wings, but will do it if deemed nessesary.
