help!
my trex 450 has this weird electrical glitch issue, at first it looked like hiccups, then after about 2 minutes a glitch sent the heli straight up into the sky,, so after that crash into a tree and my buddy saying it's the eflite esc, i removed the eflite esc and put on an ace 40amp esc, flew it and it seemed like the problem was resolved, so happy as i was, i bought a new scorpion 55amp esc to accompany the scorpion motor i just put on it, installed that, flew twice, and there is the hiccup again, scary.
so i go over every wire, no chaffing, no contact with the cf frame at all, i change the rx to an ar6200 from an ar6100, no difference, still hiccup.
so all electronics have been replaced except 2 servos.
so next i think, gosh only the ace esc has a ferrite ring so i reinstall that esc, thinking its gotta be that, some static discharge might have been glitching the whole system on both the eflite esc and the scorpion esc.
well i flew it tonight with the ace 40amp esc with the ferrite ring, only hovering,(under a tree) to see if it would hiccup, yes it did, 2 minor ones, what the heck is going on??
all electronics replaced, except 2 servos,
no wires chaffed or touching
my setup: 3 hs-65hb's cyclic
gy401 + 9257 digital servo
scorpion motor + ace rc 40amp esc or scorpion 55amp commander esc
what else am i doing wrong???
do i need to ground the tail?? the tailboom case is metal.
thanks for looking

Could be transmitter problem too. Signal might be too weak when the heli flys further away. Does it have frequency/battery failsafe?

Look at the post on 9-8-2008 at @ 5 pm. It seemed to have to taken care of the glitch issue with the same/similar motor you are using.

hmmm

i will definitely try the range check, all of these glitches are occuring within a 20 foot circle, as i am hovering when i notice these glitches, they are little hiccups that move all of the cyclics, twitches really.since the major glitch, i have not flown any regular patterns or 3d as i am too afraid to lose the heli,would the range be too close for it to be a range issue??
i had to install the scorpion esc in the back because it is too big, rx in front. right now though, i still have the ace 40amp installed.

i just moved all the wires around and mounted the rx to the bottom of the battery plate to try something new, and not one glitch thru 2 batteries, i dont get this at all!! it hurts my head,,, i still feel that nervousness and do not want to try anything radical,,
is there anything else i am missing?? can wires just CLOSE to the frame generate glitches, as i put a little space with fuel tubing between the wires and the frame and now i am trying to figure out why it is NOT glitching. helicopters are like women, if its not one thing, its another.

I wouldn't think you should be getting any glitching on a 2.4 system. I have had static induced glitching on an FM system but the same heli is rock solid on a 2.4 set up. I would suspect something going on with the radio (TX). Hope you get it worked out. These kinds of problems will drive me crazy.

wondering about radio dx7

i fly 2 other helis on the same radio and have never seen any glitched on them, be sure i'll will eye those birds like a hawk today to see if any glitches come up when i fly them ,but im pretty sure ive got it narrowed to the 450 and theoretically static discharge. evidence?? moving wires led to no glitching or twitching on last two batteries flown. only in hover.

After reading many posts complaining about this problem it seems that the Spectrum 2.4 systems are very prone to glitches caused by static from the belt. The Trex 500 guys are going crazy with this and many of them are changing to the shaft drive tail to stop it. I don't believe that this is a problem with other brands and I still use FM stuff and have never had the slightest glitch since I got my first Futaba radio.
Like Heli 770 said,Try siliconing the belt and see if that helps.

Anything is possible if you don't know what you are talking about!

todays flight results

today i took the glitching 450 out and siliconed the belt, flew three awesome 3d flights no glitching,, until i recharged a battery and spooled up, more glitching!!
then i flew the 600n for a couple hours and forgot about that 450!

i took it home and stripped off the scorpion motor and tail belt. upon inspection i noticed a rather large fray, or hanging thread off of the belt about 1 inch long, fairly thin and light but none the less present! could this be the source?? can anyone weigh in on this one??

i moved the rx to the back of the heli and put the esc in front below the battery. i replaced the belt and installed a new minititan 3500kv motor along with the ace 40amp esc already on it, went out to the garage and hovered one battery, no glitch at all.
now i have to go out tomorrow and try this setup in idle up and 3d and see what happens, im hoping this was just the tailbelt fray and that i can return my scorpion motor and esc to the heli!!!
what do you all think?

Which Rx are you using? The antennae wires on a AR6100 (or E) are extremely fragile. I've had 2 instances of a single broken wire. 1 resulted in what I would describe as stutter (some roll and flips would do an extra 1/4 turn). The 2nd resulted in brown out.

I'd make certain you re-bind the model to set your failsafe to zero throttle.

If you've sparayed the belt and the problem persisted, I doubt it's a static issue. I'd make certain you have good speration of the your wiring. Don't bundle Tail/Gyro wires with cyclic servos and try to leave the speed controller wire coming from the ESC as seperate as possible.

using separate BEC?
How is the battery condition? (try a brand new battery)
any squeaky bearings?

interesting comments

yes, i did have a loose wire on the ar6100rx, it had a bit of exposed wire right at the joint and i put some liquid electric tape on it, however, the glitch occurred on BOTH rxs that i tried, an ar6200 and the original ar6100rx.
will rebind right away.
im going to unbundle some of the wires, i did, actually not intentionaly, leave the esc wire separated today from the rest of the wires.
the heli flew today with no glitches at all through 4 batteries, two old and two new ones. when i got home after flying i felt confident and i reinstalled the scorpion motor and esc and test flew it in the garage, no glitches at all. i think it was the belt
i am going to reintstall all new bearings as well, i had heard a couple guys at the field mention this like here on the thread, faulty bearings could generate electrical charges?

Bad bearings can cause RF spikes. Your belt probably was causing the problem as that loose thread would cause alot of static.

Pop off the 3 CCPM balls at the swash plate and move it around by hand to see if it is free. The swash can become stiff with dirty causing excessive loads on the servos, eventually the ESC will over heat and result in what looks like a glitch. I've had this happen to me more than once before.

glitches

Just hope you can get your issues ironed out. Glitches in the little helis seem to be SO pervasive and annoying.

You either have 'em or you don't. And once they set in, it can be a REAL nussance trying to eliminate the issue, and get expensive too.

I had a glitch on my Trex450 that was crashing me EVERY time I flew for a quite some time. I tried to trouble shoot and replace SO much different stuff to the point I got tired and broke and quit flying. (i only have one bird).

Finally think i've eliminate the issue (several new flights now) after replacing a Futaba Rx that I had removed from the case was using with a MAP antenna. I switched to a Berg mini Rx (was a good excuse too to buy a lightweight tiny Rx), and no issues since.

I had refused to believe for so long that it could be an Rx issue because it worked fine for so long. In retrospect it seems the issue most developed when I switched to the Align CF frame. I had coated the Futaba Rx in liquid elec tape, but it was up against the frame and I really think that was screwing things up.

I wonder if flying in a humid region cuts back on the possiblity of static electricity events occuring in the bird. its pretty dry throughout in the winter time.

Good luck with the issue. Off topic, but what battery do you use with all that Scorpion motor that will reliably deliver amps up to the motor's capability? I'm considering that motor maybe...

Good Day: crashed thx to dumb thumbs. Bad Day: crashed mechanical malfunction. Every Day: CRASH :)

twitch and glitch

thanks for the good vibes!!
iam going to try and fly the heli today with the scorpion setup 3d and see if there are any glitches, as of now, the one battery i flew last with no glitches is good.
yes, i believe that it was the belt, though i did treat so many symptoms at once that even if it was something else, my rushing through the system checks leaves me uninformed! so much for patience and consistency when one wants to fly now.
i use air thunder 25c 2000mah 11.1v batteries.
definitely will check the swash for unnoticed clogging or sticking, great advice!

If you have a subscription to RC Heli magazine they had an article on Electrostatid Discharge in the Feb issue. If you do not have a subscription, you'll have to wait for it to hit the book stores.
The article gave some very good tips on eliminating the static electicity.

1. Sand down powder coated booms where they contact other components to allow a conduction path.

2. Connect grounding wires that lead to your negative battery wire.

3. Spray lubricant on all rotating equipment to allow a thin film of lubrcating fluid to act as a conductor.

4. Spray static guard on your components.

5. Use electrical components with grounded metal cases.

Of the 5 tips they provided in the article #1, #2 and #4 seem like they are least likely make a mess attracting dirt and flinging lubricant all over the canopy.

It sounds as if you got it figured out that it was comming from your belt. You may still want to consider some of these tips. I had a saying when I was a mechanic in the USAF. Preventative maintenance is always cheaper than waiting for something to break.:D

I had a similar problem with my RC Tek 450. It just took off on me and I had no control of it. I trouble shot it for days trying to figure out what caused it to loose signal. I was running the Scopion HK2221-6 and the stock 35 A ESC. The only symptom I had to go on was that the motor and ESC would be screaming hot after a few minutes of hovering around. I figured the motor was drawing too many amps and caused the esc to lock up or shut down. I tried a Common Sense 35A esc and it too got screamin hot. I picked up a Scorpion 45A commander and neither the motor or ESC got more than warm. I flew that set up for almost a year with no problems at all. Then I sold the heli to make room for my Rex 600. Now I wish I had held on to it. Such is life.
One thing that helps is to trouble shoot only one component at a time, test it, eliminate it as the cause and move on to the next component. It's time consuming, but thorough.
