hotshottony,
No offense taken. Just wanted to clearify the magic juice theory... I think I am going to move a couple of things, and tear down my tail assembly and check it... Just to see if my belt is hitting the bottom of the main tail case... Some have had to grind this area out. Not sure if the belt could be rubbing there or not. It is only more down time. Plus with the swap meet coming up in two days (yea babby......) Not much time to test fly... I must be crazy but I am putting my swift 16 up for sale. It flies perfect with no issues.. I guess plastic frame and Century scores one point. Still selling it because I have this addiction to align heli's and want a 600e...Call me sick but what the heck....

yea,think i may just go ahead and pick up the GF and i have some magic here
if i need it.i have some tri-flo here what are you guys using for magic juice?do you think the new metal tail up grade may help? just thought i might pick it up at the same time.

I just picked up a GF kit and am building it now. I will mount my 6200 reciever on the bottom plate to keep it as far away from the tail boom as possible. I'll let u guys know if I get any glitches this weekend.

I've heard other people grounding thier ESC to their motor mount, that claim this is the cause of the glitches. I won't do that mod till after I test it flying with the reciever on the bottom plate.

Not sure about the metal tail upgrade. I am curious to here your flight report on the GF kit. I wanted that version to match my 2 600n's but setteled on the CF with blades as it was the first available. I may get the GF frames and swap the whole thing out if my new adjustment does not help. I moved my ESC to Option #1 in instruction manual. I also moved my ferite ring closer to the RX. I left the AR7000 installed, but moved it down to the bottom of frame mount. The farther from the belt the better. I still have the esc grounded to the frame. (better safe than sorry). Magic juice>>> I am off to Ace hardware in the morning. Talegunner says that is the place to get tri-flo spray. My dry lube evaporates and I am not sure if leaves much on the belt. It did fix the glitch but not sure...

I read somewhere to switch throttle response to standard mode on the esc to fix glitch also. I may do so later. Just think I will try it as I have it now reconfigured... I just hope the magic does not give out... that would be very and I do mean very bad JU-JU as in ju ju juice....
hotshot tony, hurry up and get that kit done. I want to fly my toy. Besides it is only a few hours to build and a couple more to get the electronics installed. You should be done by morning....LOL>>>>>

I'm just sitting here this morning reading last nights posts and Imagining some poor sap having the same issues we are and he comes to this thread and pops onto the last few pages. He calls his bubs and says DUDE! these guys are using magic juice it cures the glitch we need to go to ace and get some
Its almost as funny as another thread about this same issue and we were grounding everything and some guy shows up with {quote: what does grounding do? does it use the rotation of the blades to put power back into the batteries? :end quote}YEP! adds 10min of flight time!
I guess after all the work finding a fix it had to go this direction. LOL

Armsmaster and I will keep trying other things but for now spray that juice and fly.

Oh well, there is no wind, it stopped snowing, sun is peaking over the trees, I'm going to step outside and fly. befor the next storm hits today.

Ok, in the interest of keeping this thread serious..

The bad juju is back.. I moved my esc up front. Tail was all over the place. I was on the phone with talegunner during my test hop this morning. And yes I can fly a heli and talk on the phone at the same time... I went inside to grab some magic juice, gave the belt a complete spray and then spooled her up again. Guess what? the bad juju was gone. Flew a rock solid pack with no issues..

Now for all of those that have been following this thread here is a suggestion>>>> "GO GET SOME MAGIC JUICE TO WARD OFF THE BAD JUJU"


It is that simple untill someone figures out a better fix. At least this way you get to fly. Considdering how much $$ this little thing costs I would hate to have to turn it into a giant ceiling fan...

Interesting reading at posts everywhere about cutouts/brownouts etc. Spektrum technology was touted as the end all. From my perspective, great for small planks, not reliable yet for electric heli's. Not worth the trouble for messing around with "bandaids" trying to fix issues or gain peace of mind that problems won't strike. My solution is to for now stick with PCM, it works. No glitches for going on two years with 450. So far 500 also sweet/trouble free bird.

I think the problem has been misnamed IMO. As was noted by someone in this thread, it's the voltage spikes from the static discharge that's causing the problems.

Also what was pointed out is that the Logo 10's went through the same problems, this was with PCM/FM.

I think to blame Spektrum technology is a bit premature at this point.

It will be interesting to see if this is addressed by Align or not.

Problem is not spektrum 2.4 related. This is an ESD and has nothing to do with RF. The people who are experiencing this are mostly 2.4 simply because more people are using them now and the guys (or gals) that will jump on a new heli as soon as it releases are the people who would be more likely to jump on 2.4 as soon as it came out. So most are going to be built using 2.4. There people with FASST 2.4, PCM, FM and even 27mhz overseas that are having this issue.
I would almost bet if I cleaned my belt and got it to glitch then installed your PCM receiver that it would do the same thing.
We also have a local friend who got his before us and has had no problems, count your blessings and fly baby fly
So far the only thing that instantly stops the problem for all who have tried it is to lube the belt. that is providing they are truly having the same issue we are.

I hope you stay trouble free and in the air

BTW: I have 150+ flight on my t rex 600e using spectrum without 1 issue (except dumb thumb) and hundreds of flight with spectrum on my planes and several have 60"-80"+ wingspans and 1 with 101" so spectrum or 2.4 is as solid as it gets.

I think we should buy stock in TRI-FLOW

Sherwin-Williams Company owns Tri-Flow WHOD A THUNK! I didn't know that. Thank for the info, I get a discount there.

Laddy
You must have not read the rest of this thread. I have been using Tri-Flow with silicone spray, Armsmaster has been using Tri-flow liquid with a brush, he found some spray today at ace, and some others different brands of lube (MAGIC JO JO JUICE). Even WD-40. I'm sure the shock oil will work as well. nice thing about the tri-flow is it doesnt seem to leave an oily residue to collect dust and debris plus it comes in a spray Besides shock oil is major expensive and not all heli guys have cars as well

So does yours have CF or GF frames? and what other things have you tried to fix the problem? We can recreate our problems by simply cleaning the belt and assembly so we have been trying everthing we can think of. but so far lubeing the belt is the only sure cure.

Inkspot wouldn't approve of this, but how about a header tank full of silicon oil that drips on the belt Kind of like the old Harley's, if they don't leak, they aren't working!

WD-40 is effective and more readily available. JK has been using it since the T-rex 450 days to cure similar problems.

This ESD problem has nothing to do with Spektrum/Faast/2.4Ghz/5.8Ghz/etc. IF you have it you will continue to have it no matter what receiver you use. I am flying my 500 on PCM1024 and 2048, both exhibits same exact symptoms.

Are you guys mounting your receiver on the bottom plate away from the tail boom and still having lockouts or glitches?

It's not just ESD! Specktrum systems seem also to be sensitive to voltage fluctations and associated occurances where they go into their rebind routine. I know 2.4 GHz is way of future, but I'm not ready yet to spend money for a new radio, and risk my bird costing hundreds of dollars; for reliability that is questionably not any better and posibly worse than my PCM equipment. I see too many of my friends having problems with their Spektrum setups. And these are guys with many years experience who know about radio systems and good setups. I'm going to need to see postings of problems all over the place going away, and facts which support more bullet proof operation, before I jump on 2.4GHz bandwagon.

If you run a separate battery or BEC for the rec and it is rated for the servos your running there is no issue. The brown out / reset your referring to is usually with a BEC running off the main battery and its being over taxed causing a voltage drop. were as a normal receiver would just loose signal or be unable to power these servo the spectrum does reset. And if you will note the new 9000 reset in.5 sec as opposed to the older one taking 1-3 sec. you can also install a spectrum voltage protector that will keep it from resetting. Im glad your happy with with your system and if we didn't have so many idiots who don't check the freq board or just don't care I would not have switched ether.
As for the problem with the 500 it seems to be affecting every system and if it were a brown out /reset issue spraying tri-flow on the tail belt should not cure the problem as it does. I have not seen one issue with the GF frame ver yet I think this is in part due to the CF frame ver.
