Status: offline 		well we had the Z-Guid issue come and go, and now we have all the claims about heat related issues where Futaba Rx's are failing left and right, although we had no issues with what Futaba had out on the market this time last year, and all thru last summer.....................so has Futaba dropped the ball completly?
or is this going to be something that all the 2.4Ghz systems will suffer?

All what claims? Have I been living in a cave? I haven't read about a single issue in this forum anyway.

But man, what a scary situation!

Status: online 		It seems odd to me that it is acceptable to allow the aircraft interior temp or items inside the airplane to get to 167 degrees or better. I just can't imagine that is good for anything in the plane. Yet that is the temperature discussed in the above threads that caused the receivers to shutdown.

I don't think many of us do know the temp inside the planes. And I'm not trying to defend Futaba. However, I think most of us who are in the warmer climates do make an effort to protect the planes from heat. Dark airplane colors or large canopies open to the inside of the plane would seem to be an area that most pilots would take protective measures in warmer weather.

definately agree with Gray here........seems the only problem are from those who have placed their Rx's in an area of the aircraft where you are just asking for trouble.



Naw. Not a cave. I don't frequent those other forums too regularly and the thread on RCU was in the Futaba support forum. It's good that it was brought out here into the light of day but I would hate to see it blossom into another all out Futaba bashing like the GUID thread. Your post stating that they are "failing left and right" is a little over the top.

It ( the heat failure ) definitely needs to be addressed, but part of the answer is already known - don't superheat the receiver.

Status: offline 		There was a thread in the Futaba support forumn about receivers failing - don't know if it is still there - just got an email from Hobbico stating that my post was deleted. From what I read, yes there appears to be a problem with heat. For several weeks, Futaba USA has been waiting for Japanese Engineers to review the issue. And in the meantime, the 2.4Ghz 12Z I just purchased is sitting idle and won't be used until I have an answer. I lost a Carden Extra to the 8UA issue they had years back that everyone knew about (those that fixed them) but low lifes like me knew nothing. I really regret paying out $1500 for my brand new 12Z - really!

Dan

PS: Just remembered - I copied the whole thread yesterday - before it has had postings deleted. The thread has now been locked. I now regret my $1500 purchase even more.

Why would you say the problems are user induced if the receivers are being installed
the same way their previous receivers that had no problems were. Also I think when
a manufactor intoduces new equipment it should perform to the same standards as
their previous equipment and if there some issue alongs those lines it should be
disclosed.

I flew all last year with the Spektrum and the FASST system in Helis and Jets with no issues related to heat. Just this weekend it was 96F here in south Florida and I flew a black Patriot with the 617 FASST rx and a DF StarFireII Jet with a 608 rx without any problems. We even left it under the sun for two hours on purpose just for testing, and the rx never failed. My rx's are not exposed to the sun directly, it is in the middle of the fuselage.

I was very concerned with this issue since I have a lot of money invested in this hobby, so we took a 607 and an AR7000 and we did some tests using a heat gun; the 607 failed at 171F and the AR7000 (Thicker case) failed close to 200F.

With those results, I feel much comfortable now with either system. I always cover my airplanes with a towel when it’s really hot anyways. That’s something I learned 20 years ago. Also the instructions tells you to keep you electronics away from the heat.

Also keep in mind that the fuselage is much cooler when the airplane is in the air.

That is just my humble opinion.

For the record there were not any post deleted in that thread that I saw. And any that were was because that forum is for SUPPORT posts only. The only people that are supposed to post are the person asking a question and the Futaba techs. But that thread got out of hand and turned into a discussion thread. And as always, they lock those threads.

Futaba is fully aware of this issue. They have been working on it for a couple of weeks now but have not gotten to the point where they are ready to post anything about it. So hence, no posts. They are not hiding anything or any such nonsense. They just have not made a determination yet on what is the cause to what to do about it.
