I have been a loyal Futaba man for quite a number of years now and have resisted the temptation to switch over to JR quite a bit in the last few months. My flying partner has been giving me the business about why don't I switch over to JR. After what happened just the other day, I'm seriously considering the move. I had built a brand new Aeroworks 150 CC YAK and this would be the first model that I have the new 2.4mhz system installed in. All went well at home with testing and setting up the model so I took it to the field last Sunday for the maiden flight. The outside temperature at the field was in the middle 80's that day. I put the model together and got ready to do the range check. I had the canopy on and I am using a Smart Fly power expander 14mz with Smart Fly turbo regulator. The R6014FS receiver is installed where the sun can shine on it directly. After the 90 second range check the tranmitter automatically went to full power transmission mode. I started the engine at this time and had control of the throttle and all the control surfaces. I let the engine warm up for a couple of minutes and prepared to throttle up and check my control surfaces one last time before taxiing on to the runway. But then, I had no response from the throttle or any other servos. Looking through the canopy I could see that The receiver showed only the red light as if it had lost contact from the transmitter. I must admit I was quite baffled at the time and at a loss for what could have possibly cause the difficulty. I turned off the power to the ignition and stopped the engine and then turned off the power to the receiver. Thank goodness the engine was only running at an idle and did not power up on its own. I had the plane properly restrained, but who knows what could have happened in this situation. I waited for a while and turned the receiver back on again after about 5 minutes. The receiver went to green only to turn back to red and have no control after 3 minutes in the sun. Waited for a while longer, took off the canopy and after about 10 minutes turned on the receiver again. No dice, it cut off again after about 3 minutes and went to red. The plane was still in direct sunlight. How hot was the plane inside? I don't know but it must have been enough to cause the failures that everyone's talking about. After reading quite a few of the threads about this problem, I can only surmise that temperature is the culprit here and is a real problem for this Futaba manufactured component system. It would appear, in my opinion, that not enough R&D was performed by Futaba before releasing this problem component to the flying public. I can tell you that I would have been sorely distressed if I would have had a failure in the air with my brand new aircraft. This is most distressing. What is Futaba's remedy for this malady?

Another one....huumm,this sounds suspicios to....
