I am posting this as a service to anyone owning an Extreme Flight MXS-EXP ARF or any other Extreme Flight aircraft. You need to make sure you put Blue Loctite on all of the linkage bolts even though it is not mentioned in the manual. I lost a plane yesterday on the second fight because the elevator bolt just fell out. Don't call Extreme Flight to complain unless you wanted to be treated like crap. They will basically tell you that you are not a good enough builder and that is why if failed. Here is my story and the responce I got. I would love to hear your comments on who you think was right.
On a side note: Has anyone spoken to a Curtis Cozier at Extreme Flight, he was very rude and wanted to know if anyone else had a similar experience or if I just caught him on a bad day. Also I am tring to get ahold of the owner "Chris", does anyone have his email address? Curtis told me he forward my complaint on but I don't really believe it.

My Complaint to the BBB which they are not accredited with.
I purchased a RC airplane (48 inch MXS EXP) from them and a part failed on the second flight. The control linkage on the elevator fell off causing the plane to crash. The cause is that the part probably should have had loctite on it. I went through the manual and it never mentions loctite on these parts although it does on several other parts of the build process. I wrote the company an email stating what happened and what caused the failure and asked them to call me to discuss further. Here is the responce I got back.
"Thanks for contacting us. Our airframes are designed for intermediate to advanced builders and pilots.
There is just no way we can cover every nuance of a build in our manual.
There are things that are up to the experience and knowledge of the builder. Also any airframe can require regular inspection and maintenance."
I was a little offended by the response since he did not know anything about my experience as a pilot or builder, so I called. Curtis answers and was immediately harsh and not very friendly. I told him I was a little offended by his response. My first question was if you expect your customer to be knowledgeable why even give them a manual? His response was that it was to cover minor details. I asked why you would want to cover little details when you told me I was suppose to just know to put loctite on that part? He said you are correct we will just stop putting manuals with our product, (in a very smart tone). I asked if he would send that to me in writing. He said no and the conversation went on like this for about 15 minutes. Not once did he ever apologize for my poor experience with their product, in fact he only got more unfriendly and so did I.
In the end I told him that my purpose of the contact was to try and better their products so this did not happen to other customers and he told me that they never had complaints before. This push me over the edge and I called him some inappropriate names and we hung up.
In summary Extreme Flight products do fly good but don’t expect good customer service if the product fails.
