RE: Had a bad day ...12x, Powerbox Royal combo
I have not found out yet what the specific cause was and I may never find out but I am very confident in the JR radio and the Powerbox units. The two in combo have given me many of hundreds maybe even thousands of flights. Heck I had over 800 on my A-10 alone. I realize that every system has its failure points because nothing is 100% perfect. I am also very meticulous in trying to find the problem, that is the reason for this tread and also why I will be sending in the radio in for a checkup. I appreciate all the advise and comments.

It is possible that this is all just a "perfect storm" of crap that all came together to make an insolvable problem. I hear you, if it is a problem you can fix post fact, then it's worth doing! I think that I would have made a B-line for the runway after I noted a problem with my connection to the jet and you probably did the same thing but couldn't make it when the engine died.
Its been a long time since I saw you man, I'm glad you're still flying.
Billy is a good stick, great builder and a very meticulous flyer. He flies well and knows when his airplane is out of whack, he has more successful single engine A-10 flights than most of us have on ANY airplane.

A quote recently seen criticising Wren engines !
"Forums are for the free exchange of ideas and information good or bad.

so which way WOULD you like it ?

David its very sad that you found it neccessary to trawl through an old thread to find that quote from me to try and justify your constant promotion of an off subject system.
To me Weatronics is taking on the persona of a sect that goes door too door to thrust religion in your face, close the curtains and don't answer the door.
Don't get me wrong I am all for new ideas and technology and when Weatronics first came out I was very interested, but your constant diatribe on it has put a damper on the subject for me.

Billy is a GREAT stick and great builder!! A couple years ago he put together a Skymaster F-15 for me and it was laid out beautifully indeed. Billy has always been extraordinarily helpful and extremely knowledgeable when it comes to jet flying. Dude, I hope you find out what happened....that truly blows brah ;(

That's why if at all possible finding out what happened here is very important. As a turbine newbie, if this happens to a guy who is known to be top-shelf, I can't help but be concerned over my jets.
It's like the RC version of, "Ask not for whom the bell tolls, it tolls for thee."

Or like what my grandpa told me when he was in the war, " Don't worry about the bullet with your name on it, it's the one that reads, ' To whom it may concern' "

What you experienced is the inability of regulator systems to provide enough power under load. Manufacturers of these gizmos and their way of calculating power dissipation of the regulators used are all way over optimistic.
They rely on the ignorance of the user.
The problems with Spektrum (and by unfortunate association JR as well) is a fundamental RX design flaw that will keep on destroying jets. It may be made worse by power issues but I dont think it is the main cause.

Billy, I'm very sorry for your loss and hope you'll get to the bottom of it.

I would like to warn against not using a powerbox / power expander with power hungry servos like JR8711. This cost me one jet. It could be a futaba rx limitation but I recently lost a mig 29 that had 2 8711 on stabs and various digital servos on everything else. I only had a smartfly regulator feeding current to the rx. After the crash I realized I could prevent the stab servos from moving with my hand. There was simply not enough power going to the servo. In my shop I have verified that this issue wasn't present with a power expander.

Ok, I'll bite, what is the fundamental RX design flaw that you have mentioned several times and suggested a ''class action'' suit over?

Is it possible that you may have had a servo binding creating a large load on the system? It could be a higher load than the regulators can handle.
I had an F-15 with servos on the gear doors. When one gear hung up, the door could not close. This fried the servo causing a dead short. the shorted servo put a big load on the system, enough to melt the leads from both rx packs. I was running a futaba rx without regulators. The ecu detected the low voltage from the rx and shut off. I had just enough juice to land the plane before both batteries crapped out.
Things like this are sometimes hard to detect after a crash as assumptions would be that the damage was from the crash.

Already did that, found a bunch of pics by you claiming to be bad solder joints on a JR 1221. Problem is, it doesn't look like a JR 1221. Another comment by you claiming that the chipset is not being used according to manufacturer's spec( or something like that) with no explanation because us laymen wouldn't understand. No where else did I find any reports of a fundamental design flaw in JR receivers by anyone other than you.
If you have some evidence, post a link.

Then it cannot be true of course. The pictures are photo-shopped and the chip vendor designers and engineers has no idea what their own product is about. Same thing when the guy found the earth was round, it was just him.

But then its just a little solder, cant be that important....

RE: Had a bad day ...12x, Powerbox Royal combo
Just thought I would check one NIB of the last (probably mnf 2010) satellite spektrum(JR) remote RX's for an update to this issue. Something about the aerial wire seemed odd. So I took this picture of the goo covering the joint. Second Pic is off the goo softened using flux fluid. Wanted to remove the goo to see whats up. Before i could the wire fell away. Took some closeup of the joint and wire. Note this has only been taken out the packaging a minute or so before. If I did not remove the covers I would not have spotted this.
