I have an assortment of parts for the Estes Skywinder Model EST 2077 that maybe someone could use since this model (as far as I know) is no longer in production. You can see what parts I have highlighted in yellow in the illustration below and circled in blue pen is what I do not have in order to complete the kit. Asking $20 shipped to anywhere in lower 48. Let me know if any questions. Thanks, Art G.
