I have two jj the 1400 and 1800 Ive had problems with the 1400 ,was still under warranty a jj central Mark replace it no questions asked. I felt that the service was great, thats why im getting a 3000 as far a resale, im in this for my own personal flying pleasure. If I happen to have sale one of my plane with a jj in it, I would welcome any interested buyer out to the flying field. thats the only way I would do it. sort like see for your self type of thing.
