I have owned both the GP and Lou Andrews (AAMCO) Aeromaster 60 kit for about 2 yrs. I just finished the GP Aeromaster 60 and decided what the heck, lets build the Lou Andrews Aeromaster Too kit. Don't plan on flying either till spring. I think there is a shelve life to kits. Not sure how old kit is, I got it on RCU kit buy. Kit is complete however metal hardware such as screws, nuts are rusty or very discolored. Also, the 1/16 inch balsa isn't in real good shape. The Aeromaster's are identical version for version except the AAMCO kit uses rubber bands to attach the wings and landing gear. Should I convert these to screw attachment or build per plans ???????????
