So would you trust a $10,000 plane to a DX7?
Hearing about people getting locked out, and personally witnessing someone getting locked out of the 6-channel receiver has me worried.
Is it worth the risk? How confident are you in your DX7?

Not until the critical system low voltage spike reboot issue is resolved as soft failure or other innocuous non issue. The designer could not possibly have been a modeler.

if you don’t trust it in a $10k plane, you shouldn’t trust it in a $10.00 plane.
its not the cost of the plane, but what it could do to any people around you should far out way model cost.
if its set up right and has suitable power supply for safe flying, the model cost is irrelevant.

I have a friend who trusts an $11k dollar plane to it, so yeah, $10k is no problem. I've got it in a $5k plane, a $4k plane, and a $3k helicopter so if you add them up, I'm over that amount. 
The key is to set it up right, just like anything else. The people who are having problems aren't addressing the power needs of the system. Another thing you can do (that I always do) is test the receivers out for a few flights in something cheap, like a trainer to be sure of their reliability.

FM systems are far more robust with respect to low voltage and don't shut down in the event of a momentary low voltage spike.

I'd much rather have a system that can't get shot down by someone accidentally turning on a transmitter, is immune to noise from the systems on the plane, and will insure that the wrong model isn't selected, in exchange for simply properly setting up my equipment. If you are someone who can't set up their stuff correctly, then you are certainly better off with FM, since a 2.4 will only guard you from other people's carelessness, while an FM will protect you from yourself.

I would not trust any valuable airplane to the DX-7. I put my DX-7 in a 35% gasser and it almost crashed it (loss of control). On the ground, the problem is reproducible yet when I sent it in for servicing Horizon Hobby refuses to acknowledge a problem. Details: http://www.rcuniverse.com/forum/m_60...tm.htm#6093186. Judge for yourself if it is a setup issue or no - I have convinced myself it is not by trouble-shooting component by component.
When I called the servicing center, I explained that this large airplane can easily kill someone, and that I fly it in competitions where there is spectator attendance, their response is: "We won't be responsible because it won't be possible to prove that it's a our radio".

If I read your test corectly - it would seem a comparison using another tx would quicl;y isolate things
You said "jiggling the TX makes the problem occur?
did I read this right?
assuming NO ONE has been inside the tx----------- it sounds like a mechanical problem in the TX
but then that's just a guess, based on your input.

It does definitely sound like a physical problem in the transmitter in your case. I'd say that's no reason to avoid Spektrum wholesale, you can come across a defective transmitter with any brand or technology.

Hi Dick Hanson, Ncrego,
You are right, it obviously looks like a mechanical problem wiht the transmitter. But, it is not possible to convince their service department of this. They insist it must be some other component in my system, such as the powerbox. Even though I clearly described, both on the phone and on the letter I sent them, that jiggling the transmitter causes the problem 100% of the time.
Ncrego, I agree that a defective product happens, and should not be enough to swear off a brand. However, a defective product that is not supported is a different story. For example, if I buy a DA engine I am not so concerned that there may be a defect, because I know that if there is, the issue will be dealt with. With Spektrum, it is the opposite. Complete stonewall. Therefore, I conclude any product you buy from Spektrum is a risk: if it works, fine, but if it doesn't, it will sit on the shelf. In my experience, defects occur with sufficient frequency that support is warranted to be one of the major criteria to decide which company to deal with. This is why will never buy from Spektrum again.
