Sounds to me that Futaba needs a big fat lawsuit to get their attention. Unfortunately, many large corporations need to be slapped upside their financial head before they get their arses in gear and fix known design problems. The automotive industry routinely uses risk assessment to determine if they will do a recall on defective products. I believe Futaba is doing the same thing here.

If someone were to get injured, Futaba could face a criminal negligence suit. And some say we don't need tort attorneys.

Question:
50C is the max temp Futaba recommends for the rx’s (heat), the ones I’ve read and I have tested failed over 50C and some 70C, can you argue that in court? If one rx failed over 50C?

What ignorant airheads on forums like this don't realize at this point, is that in their campaign of bashing Futaba and hoping for a lawsuit on the hyped heat-issue, they will actually put light on the fact that is it safe at all for average-joe to fly 30% or bigger scale aircraft...... Or for that matter; a standard .40 size trainer.
Someone could get seriously hurt if hit in the head by a small aircraft, not to think about of a airhead flying a 33% scale forgets to charge the batteries or just lacks general flying skills and smashes it into the pits. Is it safe???No!
Shall all activity with RC-controlled aircrafts be banned for security reasons???
We all like to blame the radio-gear for our mistakes.

The thread over at RCU on the "heat-issue" is closed by moderator, it should be done here at RR as well.

As far as I know, there have been no reports of this being an issue in flight. This is only duplicated by leaving an aircraft out in the sun to bake. The greenhouse effect is more of an issue with giant scale airplanes than helis. Heli canopies generally aren't sealed up like airplanes.

Doing as most pilots do, throwing a white towel over your aircraft, will prevent this issue in most cases. I prefer to keep my helis on a table under my shade tent.

Soon we'll be paying $1000.00 for a receiver so Futaba can cover their liability insurance. This attitude has ruined everything from Guns to GA Aircraft to medicine, ect.

where are you seeing the heat issues being discussed?
i was involved with the long and (Yaaaaaaaaaawn) boring and totally stupid discussion over at RCU where a few of us had to communicate via PM's because we were laughing so hard at some of the bozo's that were posting with nothing to back up there claims.

personally i have tested all my Futaba Rx's and found no issues in what would be considered tollerable heat for flying.........anything beyond those temps would just be health issues at risk.

if there really was an issue, and especially one that would be considered life threatening when using Futaba 2.4 Rx's, then you can bet Futaba would do a recall..........

So Hirobofly and ka6fty, are you advocating that irresponsible companies should continue to be irresponsible because they have no powerful incentive to do otherwise? Ford did this with the gas-tank- exploding Pinto in the 70's and the rollover prone Explorer in the 90's(and they tried to blame that one on Firestone). Shame, shame! Unfortunately, lawsuits seem to be the only way to keep corporations responsible?

No, we will buy JR, Spektrum, etc. At least JR/Spektrum has demonstrated appropriate corporate responsibility by fixing their voltage brownout issue. That's more than I can say for Futaba.

summerwind, I had a crash with a plank this weekend. I've flown planks for 38+ years - no pilot error here. After a very careful examination of the crashed parts, I can't explain this crash with any other reason other than receiver failure of a Futaba 607. Outside air temp was about 102° F. at the field. The aircraft was an electric - so no muffler or engine heat to consider. I'm guessing that with my clear canopy installed the inside temp exceeded the limits of the receiver. This was a typical installation. The product appears to have simply failed under conditions that are typical of its intended use.

I have always used Futaba radios along with Kraft, Heathkit and Airtronics in the early days. So I'm not likely to be a Futaba basher, nor am I a contrarian! One of my earlier post on this thread even somewhat condescendingly defended the big F. However, I do believe there could be something wrong with Futaba's 2.4 receivers in high temperature climates.

Having many Futaba 2.4 Ghz receivers in my aircrafts, I am now becoming reluctant to fly and possibly sacrifice more aircraft until this issue is put to bed. And that doesn't mean Futaba's lame ass recommendation to simply not fly with a receiver beyond a certain temperature typically found in our models.

Here is my opinion.
I lost two airplanes (brownout) with JR/Spektrum, it took them 14 months to come out with a fix. Do you have any idea how many airplanes were lost? And everytime we call Horizon "there is no issues with the system" a whole year man.

At least Futaba came out with a fix for the ZGUID issue in a month.

For the so called receiver "heat issue"

I and several others have tested.

607 failed at 171*F
617 failed at 168*F
608 failed at 182*F
6014 failed at 161*F

Of course this is just my opinion.

rexxigpilot,

The electronics in most of your planes and for that matter most f our heli's all fail at about the same temp. Read the instructions that come with the 401 gyro. The gyro fails at 45degC (115degF). Does that mean that every heli that has crashed is due to a gyro failure? I think not. This gyro has been used by many heli pilots, plane pilots, and jet pilots. It has been used for many years and in every application you can think of. In fact, I would bet that some of the 33% plane flyers have a 401 installed to help out with torque rolls. Have they ever failed?

When the dust clears, we will all see that this is just something that has been blown way out of proportion. Keep flying and protect your planes from heat like normal.
