Hey Greg, I gotta tell ya, I'm very impressed with the quality of the Tamjets F-16. I just hinged my gear doors and did use the music wire option..not sure it was necassary but I did it anyway.. I'm going to install the air cylinders tonight and hopefully work on the servos for the elevons or tailerons whatever the correct term is...I'm learning more everyday about these jets!!! My concern now is the brakes...totally new concept for me....I Truly appreciate all the help!! Rick
