Status: offline 		my biggest scare of all time was this morning and i really am glad no one got hurt. i also need to make a formal apology to anyone else who has had an issue with a Futaba 6014 2.4Ghz Rx shutting down from heat, and i can also say i now know how bad it feels.
i'm not going to bash Futaba, and i am going to keep on using all my Futaba gear, especially since i just bought the 12Z this year, but i am deeply dissapointed at losing one of my best airplanes in the learning process.
the Skybolt was in the air at the time, and after we collected all the scraps and set it in under the shade, the Rx after about 2-3 minutes cooling time, finally went from Red to Green and control of the servos was reinstated.
i guess it will also be best to send the Rx in and have it checked.

Status: online 		Summerwind, I know what you felt. I lost a scratch built last week from a battery failure, it open and turned off everything airborne. This was with a 72mhz Futaba system. One of the welded tabs let loose from the battery cell. THe plane circled for several minutes, loosing about 5 ft of elevation each revolution. Its a bad feeling not having any control and the plane is still flying.

JR is making hay off this problem. The last Model Avaiation on the back cover, has a JR/Spectrum ad saying that their receiver will still work when the case starts to deform at 307 degrees. Futaba had a notice on their site and there was a thread that both got pulled down about the FUtaba heat issue. I haven't seen anything more on FUtabas site no here on RCUniverse. I'm not flying 2.4, but I'm the web master for our club and I have a page with all known (verified) issues with radios. WWW.Sloflyers.com

Sorry about the plane, and I would send in the receiver for a checkup and tell them you would like a replacement plane also.

Don

Status: offline 		Im sorry to here of your crash but im so glad that more of the truth about the Futaba
receivers are comming to light because at some point Futaba will have to step up to
the plate and correct the problem are they will loose a lot of sales.

Status: offline 		you know the most ironic part of this is that 2.4Ghz technology is what brought me back to modeling after a 15 year layoff.............in the past i had been shot down twice by the same guy in our club when he switched on his radio.......(yeah he's an idiot, but owned the local hobby shop too)............and had several hits in areas around our field.

with 2.4 Ghz i figure we are safe from that, but to have a radio lose communication was a pure gut wrenching event.................funny thing is, before i bought the 12Z with this fabulous 14 channel Rx, i flew the Skybolt since last summer with the 6EX 2.4.....................never an issue.

Status: offline 		Are you sure it was heat problem ? Did you measuse heat of the receiver.

I really don't know how could receiver get so hot in the plane when you are flying.

In my pilon racer i have receiver near 80A regulator and battery and max. temperature that i have measured was 40C "104F" on the receiver.

On my large planes i have a lot of space and my receiver is not even warm.



I know they have heat problem and they should fix that. But here max. outside temperature when i fly is 30C so i think i will be ok. Until i crash

Status: offline 		skorp,

i agree, but no matter how you cut it, i had no control of the model.
i have sent Bill Baxter a link to this thread as well as emailed Hobbico............but i think we all know that i am SOL on this and they will just try to sweep this under the rug............i haven't posted this incident on the other forums yet so as to give Bill a chance to let me know what is going to happen on this, but i won't wait a whole lot longer as i have also PM'ed Bill with regards to some Futaba analog servos that rotate to an extreme position on boot up of which he has not replied either.

i love Futaba radios, but enough is enough................there are some quirks in their system, and it's not right for modelers who are Futaba users since day one, let alone new users, to do all the Beta testing at our expense.........................scariest part is, what if someone had been injured?

Status: offline 		You are right. I have also problem with graupner (JR) 5077 servos. When i turn on the transmitter servos go to the one side and then jump back.

This is not big problem for me, because my servos don't go over limit. But may be problem in some planes when servo go over limit.

Futaba really need to fix that. I will be happy to send back my receivers to be fixed for that.

Futaba have great system, but they should improve it to be perfect system.

Status: offline 		skorp,

the problem i had was with the little 3114's that are recommended by Great Planes for use in their Reactor Bipe...........putting two barndoors on a little servo works for normal operation and flying, but when the Rx boots up, they get Whammed!!.....stripped out 4 of them now. what adds to it is when trying to plug the ESC into the Lipo.........if you don't get it connected just right the first try, then you end up touching the connectors again, and then the poor little 3114 gets screwed in the process...................i have posted this in the Futaba mfg. board and it got lost.

Status: offline 		I’m sorry to hear about the problem with the Futaba equipment. I’ve used their servos for more than 20 years and my 9C Super 72 mhz for a number of years with great results. I’m disappointed that Futaba has not been more aggressive with solving their 2.4 problems. To make it worse the other leading 2.4 radio manufacturer is mocking Futaba in their ads. Very sad to see this kind of stuff happen to Futaba and then they don’t do anything about it. I hope they wake up soon!

Status: offline 		I have to say that if more people would take heed of true issues with these recievers we would have less crashes.

I posted a problem with these and other recievers a while back and everyone wanted to blame the install or said that i was making the issue up.

If interested please thake a look in this thread and keep it alive so that more people can be warned.

Status: offline 		Have you checked to see what temp your receiver shuts down at? It appears that some cut off as low as 130 while others at 150 or higher. Was your receiver under a bubble canopy?

Later;
