RE: ? Your first RC plane
My first r/c plane was a California Coaster, a 110" sail plane built from RCM plans around 1975.
I found it in a hobby shop near the Santa Monica airport, it was all basla with a Dejellski wing (sheet balsa with exposed half ribs on the bottom) all purple and every other rib bay was white.
I put a World Models single stick radio in it and got around 20 high start and power pod flights on it before a very windy day put it in the airplane grave yard.
My second plane was a Hobbi Hawk.
