FASST, HEAT, I give up, Suggestions?

[wallygator]

Why , because it still works SO-FAR?
How do you know it doesn't damage it?
You risk damaging any electrical product pushing it to failure.
just makes sense to me.

How do I know this? Because I am a superior intelligent human being that nobody else can measure up to.You wouldn't understand....[/quote]


How do I know this, Maybe it's the years spent building testing missle and satellite components for large aerospace company that will remain nameless. But then again I was dead for 34 minutes and that may have affected my memory of the subject, hence my sig.

Tin Man: I have problems seeing my H9 27% Extra especially on overcast days. Other than that I is a great plane. What plane are you going with now? I bought an H9 Carden Yak I was going to switch the gear out with. I have all projects on hold till I get my radio problems resolved. I have sold off most of my 72mhz RX's already.

Nope. In one case, the STM, it was powered through a 6s2p 8000mah via ubec with less than 10% of the battery used. In the second case, the quarter scale Kat, it was powered via a 1800mah NiCd with a fresh charge. Less than 10 minutes total receiver 'on' time. I had range tested it, again that day, out to about 75 yards with me between the radio and the plane! Trying to give it an 'extra tough' test. CDI was on a separate battery to avoid any potential interference.

I'm in a pretty clean area with regards to other waves floating around. Yeah, we have 2.4g internet in town. The closest broadcasting field is about 2 miles away. Again though, it is this one receiver. 7 other FASST planes are having no issues. Only two others are running 6014s. The rest are on 607s and 617s.

Those two other 6014s are run pretty much on the same days so have experienced like weather. Installations aren't much different with regards to potential heat. I don't yet think heat has been an issue in any of my situations. Unfortunately, with both of these two 'crashed' installs, the receiver has not been readily accessible, so the old finger test for warm has not been an option. However the recent crash left it accessible and without powering it down, and in less than 3 minutes to get to the model, I did reach inside to turn the receiver to be able to see the LEDs. It was not even warm at that moment.

At the time of lost control, I was making a 'gentle' aileron turn.... so was easy on just two servos... the other three would have only been slightly fighting the wind to hold position and it was a very gentle turn. As this was a new model, 4th flight... I did a very careful look over to make sure I did not have any stray wires or bad connections before take off. This 'works' three times at much greater distances and then fails on the fourth... does not make sense. I just want to 'know' why.

Yea I'm starting to miss the 'ol 27% H9... OK, not too much. Mine was a bit on the heavy side, but that's water under the bridge. And it'll likely live on: a friend and I are probably going to fix her, and throw in a Saito 180 he has laying around. And without the Power Expander, ignition, extra batts, etc. it should be a lot lighter. It'll just be a practice plane to throw around the sky. Also just received a lighter Graphtec landing gear (well, to replace another one that I ended up having to brace with steel bar stock as it delaminated). Had also just replaced the aileron and rudder servos the day before the crash. That's typical for my luck: buy new stuff for old plane, old plane crashes. Ugh.

As for where the DA-50, etc. are going, I'm torn between the H9 Carden Yak, Aeroworks (Yak), Dietrich Extra, Quique Yak, TOC 30% Yak, or perhaps a less expensive Yak from Dawghouse RC. Decisions, decisions. One thing I don't like is that I ran HiTec 5645s in the 27%'er--and 3 are brand-new. Now it seems like every damned 30% ARF wants $125 servos, nothing less. Wish I hadn't bought those new 5645s. And I came --><-- that close to going for 5955s instead. Ugh, again.


You are now returned to your regularly scheduled any FASST crash, any reason, debate, already in progress!

That model needs nothing but JR 821 servos on 6 volts --or 100 inch ounces and proper linkage adjustments
here is my clone of that model ( I used the cowl) mine weighs under 14 lbs but I have flown the stock ones too.
This setup on ZDZ40 eats em alive.

No one kooked a receiver to 300.
Are you referring to my analogy of the DA 150 cooking at 300f. as "brand XX receiver cooking at 300f. "???
I hate to bust your bubble but a DA 150 is a motor and not a "brand XX receiver"
Just wanted to set you strait.

You can see a DA 150 hear http://www.desertaircraft.com/
Its a 150cc motor.

[hpapilot]

buttface, pretty sure he was referring to the Spektrum challenge that was discussed a while ago where they supposedly heated an AR9000 to something like 307.

Yes someone cooked a receiver to 300 deg. Spektrum
(brand XX) has an ad telling us.
If you want to talk about DA 150 I suggest you start your own thread.

Is there any way to hide posts and posters so I can't see them?
I just can't stand gorillas .

Cannot be straighter than that...

Aw stop all this blabber about heat and futaba receivers. Its silly, just silly.

Not sure what you meant by "that model" but if it was the 27% H9 Extra I felt the 5945s were adequate on that plane (though I did throw a 8611 on the rudder for a period--worked great but a bit overkill). If the 821s worked OK for you, that's great considering they have about half the torque of 5945s.

But what I meant about servos and 30% ARFs wasn't regarding the H9 Extra. The others, or most of them, that I listed seem to want 8611/8711 servos. For example: "Quique... recommends JR 8611A or JR 8711 servos."

BTW: I would imagine the H9 Extra'd be great at under 14 lbs. I won't even mention how much heavier mine is, but suffice to say it's heavy for that size plane, with only a 78" wing span.

To keep this marginally on-topic let me just state the servo discussion is mainly for power management, which could effect heat, which I'd like to keep in check with FASST. See, back on topic!

After all this controversy it would be irresponsible to operate a 6014. I am afraid to be found negligent if I injured a person using known defective equipment. So...as the start of the thread says, I give up (for now). I Put the 72 Mz module from my 9ZAP in the 10C Tx and will continue to fly my 149DPs until Futaba makes FAAST safer.
