I am forced to sell this beautiful Corsair kit. This will come with the Byron retract tail gear and the purr power exhaust/motor mount. There is no engine or main retracts with this sale. It was designed for a Sachs Dolmer 4.2 or Quadra 50. I was thinking of using a DA 50 or G-62. I have owned this kit since the late 1980's and it has never been started.
