question: I bought a plane recently. The owner has a dx18 as I do also. I imported the model to my radio but it would not bind. Tried many times but would not work. Then went to a blank model< manually put in all the data just like his. Still would not bind. I ended up binding to a blank model first, then putting in all the data. worked fine. I need to rebind but afraid I will lose and have to start over. Ideas??
