Too bad you had the crash. However, you are to blame. I have a lot of experience with Extreme Flight RC, have several of their planes which are outstanding and I have yet to have an in-flight failure with any of them.

It is your responsibility to make sure all the linkages and moving parts are secure and this regularly. The use of Loctite or other methods to secure nuts (such as nylon lock nuts or even cyano) is a common procedure in our hobby. Whether their manual states it or not, for someone who is supposed to be at least intermediate there is simply no excuse.

I had to deal with Extreme Flight for after sale issues a couple of times, and each time they were responsive, polite and gave me full satisfaction. The only time I was a little puzzled was when I sent them an email about an assembly dilemma I was having with the torque motor that came along with the 78" Extra and they told me theye were having problems with that power set anyway and offered me a refund or store credit. That's great, but I wish they had sort of reached out to all their customer who had bought that plane. They could have even pur a warning on their site if sending emails to all was that complicated. After all, I doubt they sold thousands of Extra 78" ARFs given it is a rather high end model.

Anyway, I still think these guys are one of the best out there, not only in terms of the quality of their planes but also their service.
