LOL.

The max temp on the Raptor's rx (617) was 131F, only for an hour under direct sun since I was concern for my other equipment, It's really hot down here today 93F and humitity is bad.

I have DF Jet (StarFireII) that has the 608 rx in it, I'll see if I have time tomorrow to test it.

Regards,
Doug.

That aside, this morning I used a heat gun to try and induce the problem, and could not get it to shut down, I did not have a temp gun, but I did get the RX a lot hotter than I would feel comfortable with (very, very hot to touch) So I personally feel comfortable using the system, I remove the canopy from the plane whilst sitting on the ground and park it in the shade, so that removes the baking effect on the ground.

Thats the way to do it,better than complaining, look for a solution,i was thinking in doing that to my 28% and going back to the good old foam wrapping.i will get some good old solar film for the canopy too.

1st pic shows the position of RX and the relationship to the duct on the outside of the fuse, others just show what I used, I openned up a hole most of the size of the duct, which is simply a 3W cable exit guide facing forward.

Once again, you have severely missed the point! By now they either know that there is definitely an issue, or there is definitely not an issue, or they are too dense to figure it out. I would like to believe that the third option is not the correct one since, if true, they should not be designing radios for us.

So they can come on here and say definitively yes or no to the issue. I am not talking about determining the details of why & how it happens, just is there or is there NOT an issue!!!

As stated before, anyone of us with access to a heat gun (or some other way to heat up the RXs, like a styrofoam box and a big light bulb), a thermocouple, and ten 6014 RXs could do this in three hours. Why can't they???

To date there are three issues with the Futaba FASST Rx:

1) Low output voltage
2) Temperature sensitivity
3) Servos going to full throw in one direction when switching the Rx on

How many of you experience the third issue also?

Nice

RC Dart, that is a good idea. What are your thoughts on the Fromeco Fan over the receiver. I think that would only work if the receiver was causing the heat. If it's the ambient temp., then it would just circulate the hot air. My Dalton (which I am about to maiden) had two receivers, and greeves pipes. There is no pipe tunnel, so I am a little concerned.

[Woketman]

If the RX is under a clear canopy and is getting hit with direct sunlight (on a mostly black plastic case), then the fan will help a lot. It will convectively cool the receiver as the local air is still way cooler than the RX case.

Good point

For a guy who professes not to be an engineer you seem to think you have a very firm grasp of what it takes from an engineering standpoint to diagnose and fix a potentially complex problem.

I'm impressed. Perhaps you should hop on a jet over to Japan and set those dolts straight!!

[rcdart]

Prizzy, my plane has BMB pipes and no pipe tunnel, so our set up is simular, a fan over the rx may help, but what I have done is very effective, uses no power, should be very reliable, sources cool fresh air, and costs about $2.00. It works for me, and thats what I consider important, others must make up their own mind.

[prizzy]

What is the intake actually? Did you make it, or is it used for some other purpose?
