I bought a second 104 to replace my first one.
I set it up with the best components and glued everything I could reach.
On the 42nd flight, when I stopped rolling in a maneuver, the tail kept rotating and snapped off. All that was holding the tail on was my pull-pull cable. I was able to land it without damaging anything but the fuse.
I called EF and explained the story. They told me to email them pictures. I did. They responded saying that I must have had a poor setup (bad servos) which could have caused flutter, I didn't, my set up was perfect. I was persistent in making a point by calling them and emailing them for 3 weeks where I never received another email response and a lack of phone support. After 2 months of trying to resolve the issue, I was offered a SMALL discount on a fuse when it came in stock (which it hasn't, and its been 7 months).
I had such a bad experience that I do not want to purchase another new air-frame from them!
Also, they were very dishonest with me. They told me there were no modifications/reinforcements that need to be made to the plane. Having looked inside of their team pilots planes, it is obvious there are areas that need to be built up, reinforced, and re-glued. Their team pilots do this to thier planes. Showing a modified plane in shows, videos, and promotions, and then saying that the plane you buy is capable of the flying in the videos (out of box) pisses me off.
