After being talked into upgrading my kit order to IRS and waiting 10 months for delivery, FFR sent me the wrong frame. I received most of the IRS components, but also received a 3-link frame. Now I'm dead in the water. And FFR isn't exactly making me feel confident that they'll correct this in a timely fashion. They've admitted their mistake and told me they'd look into doing a frame swap, but I haven't heard back from them since Tuesday. Yes, I know they are extremely busy, and I'm a patient guy, but with the money these kits cost I guess I thought they'd being jumping through hoops to correct this. What a mess. Rant over....
