REDUCED!!!! I have two brand new, never installed Robart Air Retracts. I'm not sure what specific plane they fit as they were given to me by a friend for working on his RC plane. One is a steerable nose gear and the other is a main gear. Both are 7 1/2 inches long and very heavy duty. Both are listed for $150 or I will sell either one for $75. I will accept PayPal and ship to you for free.
