I totalled my balsa trainer the other day and I am trying to decide if I want to get the same plane again or get a more durable trainer. I was reading a post and someone mentioned that the aircore is a very durable trainer. Does anyone know how long it takes to build or if it comes as an arf? I could only find it as a kit and I don't have any kit building experience. If anyone knows anything about this plane I would appreciate it if they told me more about it.
