PS: My flight instructor was Mahlon Hirsch. The name may not mean anything to you but, do you remember Marx Toys??
Mahlon was Marx Toys Master Mold Maker and made all the origional molds for their die cast guns & other things. He gave me a tour through his basement once. It's like a Marx Toys Museum! He has many origionals squirreled away...
Neadless to say, He is a master craftsman and makes outstanding scale airplanes. He instructed me at 75 in 1991 and still builds & fly's today! He began building & flying models as a youth...
