I got my gear from HAWE, he makes all of the gear for the 1/16 scale Rauch airliners. They are really nice, work smooth, and heavy duty. You can contact him through Mr. Rauch's website, and expect to take a day or two for an answer, he does not speak English, and his girlfriend/wife translated for him. Got the gear in about four weeks.
I also have the 727 parts, like Peter, and also have Peter's Airbus (twin Wren 44's).
