Problems!! 14MZ 2.4 R6014FS

[BR289]

I will await Futaba's answer to what has been brought to them. Until then, I will continue to read this thread as it seems others are trying to duplicate the problem to the benefit of all of our knowledge.
I guess I am considered "Brand Loyal". I have always liked Futaba's stuff and like I have said before, I work part-time in a hobby shop ( rather large ) and have rarely seen any Futaba items returned as defective.
Heck, my best friend is a JR sponsored pilot and I still wont change!
Thanks again to all who providing good information.

Somewhere I seen a post on another web site saying the little chip that does all the 2.4 Ghz processing runs at 1600 degrees F inside the receiver. Thats why or one of the reasons the 2.7 volt thingy is used. I cant find it, I read it, I dont know if those numbers are a typo or not but if that is indeed correct then the Receiver sure as buggery will produce heat, no matter where it is. If someone can find that information great, if its wrong then great as well.

I wonder if they were refferring to the Processor speed... 1600 Hz or Mhz or what ever???

Thats possible and makes more sense...

The whole 1600 degree thing was a misunderstanding. Bill Baxter has cleared it up over at Futaba forum. It's actually 160 degrees. The degree symbol (elevated little o) somehow got changed to 0 when the spec was copy and pasted.

I am running 6014 and 617 in a couple helicopters and so far no problems. We have had 100+ temp this past weekend in So Cal and no lockouts (knock on wood). Then again the receiver in the heli is exposed to lots of airflow, and I never did check the temp of them. But I have to say, I never thought 160F is possible in a receiver, since we see that type of temperature only in 3000 watts electric motor/ESC stuff. If the internals of these receivers do reach 160F+, Futaba definitely need to do something...

The temps stated in the Support forum in RCU had nothing to do with receiver temps, but the operating temps of other types of onboard equipment. Here's the advisory:

http://www.rcuniverse.com/forum/m_7365443/tm.htm

We've seen a complaint that our thinking is to verify a problem before we do anything about it. One individual is upset with us because we cannot state that his equipment has this reported difficulty, that we don't have a fix, and cannot apply it to his equipment. What is expected? How can something be solved unless it's verified? Internet complaints/posts are not concrete, verifiable information. Futaba must be able to duplicate a difficulty before they can work on a solution.

The first posting about possible system cutouts was last Friday, and that individual's conclusion about possible causes was posted Saturday, when we're not in the office. We have been in contact with Futaba about this from the first time the post was seen...yesterday when we came in to work. People are now upset that it hasn't been solved yet, let alone what the exact problem happens to be. There are many questions to ask and tests to perform before any concrete conclusions can be drawn. Once that happens, we go from there.

Please rest assured that we are aware of what some people are seeing, and have transmitted all known information to the proper people at Futaba, Japan. The actual person who designed the Futaba R6014FS receiver is also in the loop. This is not something that's being 'swept under the rug'. The concerns are being taken very seriously.

Maybe he thought it wouldn't be too much trouble to grab a heatgun, and IR thermometer, and a 6014 and see what you guys came up with.

Question.

What if your setup is simple. All Futaba servos, extentions, switches, Duralite Batt's and regulators to 6.0 volts. No other fancy stuff. The advisory does not seem to fit or am I looking at it wrong?

The only advisory out on the 6014 right now deals with using non-Futaba equipment with that RX. Some after market servos have not worked well with the lower voltage that the 6014 uses internally. It has nothing to do with the current situation.

When Futaba designed the 6014 they used a newer generation of IC chip that operates at 2.7 volts versus 3.0 volts. They tested to make sure it worked with all existing Futaba equipment, which it does (1 exception is the 9102 servo I think). But it does have issues with some Hitec stuff and so on.

And what else do people want in light of Bill Baxter's post above?? I think it about covers it, but apparently some are not satisfied with anything less than an instantaneous response. Also keep in mind that when Bill and his team first saw this at say 9 am CDT Monday that it was 11 PM Monday night in Japan. So it really was not until the near end of our business day on Monday that anybody in Japan could even start looking at the issue.

I know who's planes these are in and I know the way he builds. If there was ever a person that builds a plane correctly, makes sure everything is isolated and free of vibration it would be in this case.

As for the lock out I was seeing, I would believe it was in my set up if it wasn't there is others with the same problem and able to duplicate exactly. I am using a more sophisticated design with a power box royal. This would prove out any voltage questions, seeing how the power box regulates the voltage to the receiver and no load from servos. I also switch the receiver inputs on the ports on the power box. This however didn't change anything with lock out. The main times I saw problems was with initial start up, once air was moving over and through the plane I had not other lock outs.

All I can do is wait and hope something is corrected with this issue soon. For now I am going to try moving the receiver into a location out of direct sunlight. I had also mounted receivers in view of canopy to give better reception.

Maybe someone could let us know what the max and min ambient opperating temps are. That would help us know if we have to quit flying if it goes over 85 deg F. I would never completely wrap electronic equipment in foam.

Maybe that is what Futaba is trying to determine right now. I understand the frustration, but since they have been at it for less than 48 hours maybe it will take a few more days for them to determine the cause and design a fix.

I doubt they will talk about ambient temps. Too many variables.
