Don't think that way, this is new technology, I tried to use the same battery 4.8 that I always use with 72Mhz when I went with Spektrum, real quickly (Lock-out) I learn that the new system needed more power, lots of pilots learn that lesson the hard way.
How much you want for those 608's? I'm ordering four this week.

Friends plane had a 72 mhx RX living in the same spot as his "new one" for around 1 year with no ill effects. I guess trying to get the info out you all let us "vent" at my Bros loss. Didnt find any heat posts for JR or Spectrum. LOL little brand war levity Thanks Hog

don't forget to order additional cooling fan/icepack upgrade option with the 608's.......it's listed under "Summer package special"

RE: Futaba 608FS reciever locout/failure due to heat
Hey guys, I've read through SEVERAL threads in the past couple hours and have been wondering only one thing about this situation. If the way I say this doesn't come off as understanding, then I'd like to say that I really don't mean to sound accusatory. Is it possible that it DID go to failsafe, but his failsafe was set to +100% throttle? I've never used failsafe (too cheap to buy PCM receivers, and too cheap to buy planes nice enough to need them), but I know that I've accidently messed up servo travel in mixes as well as simply for aircraft set-up. In fact, I've started an engine with the throttle reversed, only for it to go full-throttle on me. I left the engine running when I reversed the servo, and it went full-throttle on me again. That happened to me, and I've always considered myself to be a very cautious person. If any of the other servos didn't do anything, couldn't it be that he had the failsafe set at 100% instead of -100% or something like that?

wish we could see pictures of the mayhem...it does add a lot to enforce the claim.

....and they're a lot of fun to look at. It sucks that it happened, don't get me wrong!! The pain of crashing sucks, definitely....but there's something about havoc and mayhem that is intriguing!! I know I'm going to be burnt for saying it, but you know that everyone else was thinking it.

RE: Futaba 608FS reciever locout/failure due to heat
I have asked my friend to post the pictures of of his plane and the layout of the inside of the fuse. he said he would do so as soon as he can, as you can imagine he is very busy trying to get all the parts together and get another plane flying with his old PCM reciever.

Craig, I sure am glad we didnt hurt his burgen intrepid helo with that rx' on it must have been the big fan over the top of the rx keeping it cool. That gasser chopper is awsome see you next week when I get home, BTW I wonder do these guys want to see carnage in the pictures ar really want to see Alans electrical lay-out? I still say go JR! LOL later Hog

I received my new 10C Friday and after reading all the story about over heating and low voltage I think I'll just send it back and get my money back.

Doug, I use 2 battery's with 6v regulators. if you are using a 4.8v with the spectrum you are flirting with disaster. I really like to hear the "malarky" from the 20 year vets of this insane hobby. Oh ya I guess i need to "find another agenda" LOL Hog

Why get pis*y, didn't say you were lying. Another fellows post mentioned A&P, confused his malarky with yours, sorry.
Sounds like he had a defective receiver. Either heat sensitive or some other component failure causing the temperature rise (stalled servos, defect in power expander, high current drain somewhere heating up the receiver or just a bad receiver). Doesn't mean the whole series is bad as you want to claim.
By all means, send your stuff back to Tower and move on. There are plenty of guys waiting on backorder status.
And as far as this statement:
You're the expert, I'm sure.

Futaba has been selling a product that has no place in our hobby. Had I gotten hit by this airplane I would be suing Futaba. They need to recall these recievers and and refund all of us our money or fix the problem.

RE: Futaba 608FS reciever locout/failure due to heat
I have a Futaba 12FG and one 6014 and one 608. As yet in 90 degree heat under my huge Sukhoi canopy I have had no heat problem since installing. I did cover my receiver with white vinyl tape knowing it would keep the receiver under the canopy from seeing much heat gain.
Since the actual number of these failures seems to be small (several at best) this could all be attributed to new component failure. When I go buy computers for my company, it is typical if one is to fail, it will be within the first 30 days. There is a certain number that will do this regardless of all the testing that is done before shipping. Its the nature of electronic equipment.
We tend to forget that these incidents are actually few and far between in the grand scheme of things. They tend to get reported and blown out of proportion more today with the availability of these types of forums. Years ago, if you had a receiver, servo, etc., failure, only you and your flying buddies ever heard about them.
I remember back in the late 60's we had nicad battery failures somewhat regularly because it was new technology. When a single cell died, you crashed because the radios of the day weren't tolerant of the low voltage, much like the Spektrum systems when they first arrived.
I have in the recent past had several JR, Hitec and Airtronics servos fail out of box in the first couple of hours. No one reports these kinds of incidents because they aren't new. The only reason we are hearing so much about these radio failures is because it is new technology.

but im glad we have these forums to help us stay informed. But as for as the issue
with the heat being few and far between I dont think we can really say that because
we just dont know.
Im sure there are some that have had problems that dont come on these forums and
Futaba is sure not going to tell us how many reports of problems they know about or
how many units have been returned.
But I think what ever the problem turns out to be it will get taken care of sooner
because of these forums

I can't believe no one has caught this as of yet!!! I'm pretty excited that I'm the first one to point this out actually!
Please read hint #3 on this thread, posted by Bax: [link=http://www.rcuniverse.com/forum/m_7606959/tm.htm]Guidelines[/link]
One more thing, how do I make the quote thingy show who I'm quoting? Either way...the quote is from Craig's post in Post #9 above.

The receiver was mounted on top of a power expander
One more thing, how do I make the quote thingy show who I'm quoting? Either way...the quote is from Craig's post in Post #9 above.
Guys, If the OP is describing the power expander made by Smart-Fly, it is designed for the Rx to be mounted on top. This is commonly used in Jets and large gassers. Take a look at
http://smart-fly.com/Products/Expander/expander.htm
In fact, Power Expander 14MZ (We don't know if this product was used) is specifically designed for The Futaba 12FG, 12MZ and 14MZ for the known low signal voltage output from some of 2.4 GHz Futaba Rxs.
Sounds like an isolated defective Rx.

RE: Futaba 608FS reciever locout/failure due to heat
I believe that all 3 of the radios mentioned in the Ad (the 12Z, 12FG, and 14MZ) were all available in 72MHz versions before becoming available as FASST Transmitters. Also, notice that the picture of the regulator shows a Futaba R5014 G3 (72MHz) receiver. In fact, all of the Rx's on that page are 72MHz.
All I'm trying to say is that if Futaba says that being near a power regulator will cause my Rx to go psycho, I'm not putting my Rx near a reg regardless of what smartfly says!

You are right; all have been available 72 MHz before FASST was introduced. The pictures have not been upgraded for the new Rxs. We have about 40 jet guys in our club and most of us use Smart-Fly products (power expanders and regulators next to/on top of Rxs) with 72Mhz, 50MHz, 2.4GHz Futaba, JR, and Spectrum Rx in jets without problems.
My point is Power Expander is designed to work with Rx on top of it and has been tested in the field even for Spectrum and FASST Rxs. It is does not have a regulator for the servos thus does not heat up as other linear regulators. It only regulates input to Rx which does not produce any significant heat.
In any case, each person is responsible for their install and to follow manufacturer recommendations. In this case, one can argue that Futaba does not recommend using the FASST Rx near regulators even though it is not a powerful linear regulator for the servos producing a lot of heat. The power expander does not produce any significant heat to cause the Rx to go to 140 degrees as in the OP case. But, you can have a case in court since manufacturer does not recommend it.
Finally we all are speculating on what the cause of the crash was. No one can prove what exactly happened. Heat may or may not have been the problem.
Be Safe, have fun flying.

RE: Futaba 608FS reciever locout/failure due to heat
and then again, we've not seen one shred of evidence telling us what is what............only a guy who is a friend of a guy, who had a malfunction and this guy's airplane went berzerk in which it chewed through another guy's airplane that was on final, and then this guy's airplane demolished itself.
yep, i'm sure Futaba has a lot of explaining to do here by golly.

RE: Futaba 608FS reciever locout/failure due to heat
If you think back to the times when computer chip makers (AMD) were having so much trouble with heat when they push the chips harder and harder they were generating a lot of heat. One of cures was to lower the voltage to reduce wattage and the heat output, somewhat like what Futaba is doing with the FS6014. You have to ask yourself how hot the transmitter is getting.
