RE: Our first plane
Since you stated you & your son are both beginners, you will most probably be needing some type of support in parts & or service down the road. Also there are better first airplanes to choose from. I'd personally look at Tower hobbies or Horizon hobbies for both your original investment & service. Cubs can be challengeing to fly compaired to a trainer model that is designed for just that purpose. I'd save the Cub for a later model down the road once you and your son are proficient with a trainer. At least your asking questions before buying stuff! Good luck to both you & your son in your entry to model aviation......Gene
