I started in the late 70's and my local shop carried a full line of Kyosho ARFS. These planes were pretty tough, wood framing with some kind of foam film covering.Awsome planes flew like crud, the covering was so heavy, and the CG varied between models many times numerous lead fishing weights were added. I remember my fisrt plane was a cross between a cherokee, and a GP super sportster, brown and white. 25 sized plane that flew like a brick with a 40. Since those days I have owned them all and it is aazing how much all has progressed for th better.
