If you call the SIG people I'm sure they will be able to figure out/explain the situation. Their phone number should be in the instructions. Something definitely looks wrong. Was this a kit or ARF? Looks like ARF. Carefully re-read instructions and see if you have missed something. Doesn't look like a "dowel" type installation to me either, just a long wire. Could use 90 bend with quick link at servo or (and many don't like these but I do) ez connector after purchasing 36" wire rod a LHS. If you get rod at LHS you may also need new clevis if EXISTING clevis are metric. Was kit made in USA or Asia/China where metric stuff is used? Make sure parts are compatible and hook em up. You can still fly this weekend. Charge batteries.
