Just so you guys know, the airplane/Heli FASST systems are not the only ones having problems. The truggy and buggy race guys are also experiencing some issues with the first version 2.4Ghz Fasst receivers going into thermal protection. I think they are fixing the problem so I've read. I hope they aren't selling those receivers with the new 4PK 2.4 system. I want one of those radios... so nice...

I have some issues with Futaba FAAST too. It's not the 6014 receiver but the receivers that come with the Futaba 3PK and 3PM. I have both and they both lose bind when it's hot. After a few minutes cooling off they bind just fine again.
I run 1/8 scale buggies and used to use a JR XS3 75MHz system with synthezised receivers and never had any issues up until I switched to Futaba FAAST. The track is the same and the summers gets just as hot and muggy as before. I use the same type servos and battery packs like last year.

Logic tells me it's a temperature issue as this never happened when running the JR equipment.
Neobuggy reported drivers having this issue at the Euros. Drilling holes in the body and radio box solved the problem.

RCU Futaba Direct Support Forum says this is merely a rumour but after a few PM the answer was 'Futaba is awarew of the problem but we (Great Planes) can't do anything.

Well, IMO it would be pretty easy for Futaba Support in the US (Great Planes) to do some tests if they actually have a real electronics service department and not only an office with desks where failed part are being shipped to Japan for service.

SMan, a black chassis can get awfully hot in the summer sun. Have you tried rectifying the problem by perhaps mounting the receiver on something white?

You might try removing the sides from the receiver box and mounting the receiver on it's side with tie wraps so that it gets plenty of air flow. Futaba says that these receivers are not sensitive to vibration like the old ones were.

Read these guide lines.

I have been reading this thread over the past few days and it is interesting the number of opinions about FASST. I will only say this. My flying buddy just received his new Futuba FASST receiver. Reading the paper work that came with it, I found it was interesting that it states a heat problem under certain conditions and mentions that Futuba system are not compatibly with other systems like servos ie.

So the bottome line is that there is a problem with the FASST system.

WHAT?????????? is this guy for real???? If so I did not know that Futaba products were supposed to work with all the other brands products. The concept is cool but you need a reality check.

And some basic electronics understanding will inform you that most electronics have a heat threshold that will cause them to quit or fail at some point. Try this...disable the fans in your computer and let it get good and warm then see what happens.

Well, the cars are the way they are and it's nothing that can be changed really. My point here was that there were no issues with the JR 75MHz system, but issues with the Futaba under the same conditions.

Yes, I know more cooling will solve the problem.
My point here was that there were no issues with the JR 75MHz system, but issues with the Futaba under the same conditions and it seems like Futaba is treating this as an unconfirmed rumour and pure speculations.
To me it's pretty damn obvious there is a heat related problem and nowhere does it state the specified operating temperature of the electronics. I'm an EE myself and have to design equipment to work at certain conditions.

That's it. Futaba is a huge company and as such should take 'complaints' and reported problems seriously otherwise they WILL lose reputation and customers. Having Great Planes saying "we can't do anything because we are not connected to Futaba Japan" is a weak sauce reaction iMO.

Excellent. You now own Great Planes. What are you going to do?

OK fine...
As the owner I would set up a test at the service department and report the findings to Futaba Corp in Japan. I am after all, as an owner of the distributor and the official service department for Futaba in the US, pretty interested in keeping up sales and do my best to work with them and promote the products.

Now..... you now own Futaba Corp in Japan. How do you reply when the distributor of your product on one of the largest markets in the world investigates and reports serious issues (with lab results) about a product?

Would you please post exactly what you read that makes you think the FASST system has a "problem"?

I think I can help.

Hitec makes servos that do not work with some Futaba radios. Clearly Futaba's fault!! What other possible explanation could there be.

Some people who have installed and operated their 6014 FASST RXs beyond what Futaba recommends (in high heat environments) have had spurious issues. Again, clearly Futaba's fault. Any equipment problem is ALWAYS the fault of equipment itself and NEVER the fault of the person using it.

Perhaps it is you who needs help in understanding simple basic modeler logic??

Silent-AV8R,
Let me understand this correctly, you mean if a chainsaw chops off some morons leg because he was using it improperly it is NOT his fault, but the fault of the chainsaw and the chainsaw manufacturer or if I am driving 100 miles an hour down the freeway in rush hour traffic its not my fault if I get into an accident. I have to say thanks for clearing that up I went through life using common sense now I can stop because I can go ahead and behave like a senseless idiot and blame all of it on the equipment and manufacturer.

Once again common sense here rules. Futaba is not to blame if you guys use your equipment beyond what they say. Rule of thumb should be, if it is too hot for a person to be standing in the sun you should not leave your equipment in the sun.

Well the problem here is that Futaba never stated the safe temperature range. At least this is true for the FASST system used for the 3PK and 3PM.
If they did PLEASE point me to it because I really like to see it.

Page 10 3pk manual

Receiver Vibration and Waterproofing
The receiver contains precision electronic parts. Be sure to avoid vibration, shock, and temperature extremes.

By the way, if you don't know what temperature extremes are then you would have to call and find out. That of course is a user responsibility.
good luck

Thank you but, there is no definition of 'temperature extremes' and it's certainly NOT the users responsibility to find out what Futaba specifies as a safe temperature range.
Have you EVER seen any consumer electronics that doesn't come with this info clearly printed in the manual!? (Except RC related products).

If these 'issues' were to happen in any car of a certain brand there would be a major recall and possibly class action lawsuits LOL.
Do you think Ford/GM/Toyota or whoever would get away this easy if their engine ECU over heated and failed and there were no written specs about safe operating temperatures? Not in a million years.

Seriously, why is there such a reluctant attitude from Futaba with this, and why are the fanboys coming in and defending. I mean there is an issue but it would have been a non-issue if it was clearly stated that we are not supposed to run the Rx at more than xxx F.
Besides this the early batch of FASST receivers (for cars) didn't have this issue.
