I am doing some updating/repairs on a 1/3rd scale cub. I'm not sure of the brand of kit it was built from. It was purchased at a swap meet and belongs to a club mate of mine. It has Cirrus CS-28R servos in it. They have a 3 wire lead with exposed pins. These will not be used. We are going to update everything. As well as recover as a Grasshopper. I can not find any info on these servos other than a few for sale. I am just trying to figure out how old they and the plane is. Anyone have any idea?

Those servos are from the 80's designed for old AM systems
They are a novelty now
