First of all I know many have had issues with everything from "brown outs", to "glitch\hickups", with their 500's. I am in the group with the glitches\hickups. I guess the biggest dissappointment is that the whole purpose of going "spectrum" was to do away with the RF interference which is inherent with heli's. I know that nothing is "bullet proof" but my glitching was so severe you could not even fly the heli. Tried two different RX's, two different esc's, one with a seperate bec. I even did the ground strap from the neg on the battery to the motor mount. My buddy tailgunner was having small hickups that he posted about, that got several replies. My first flight was without issue when I first set up the heli with the DX6i I got with the new Blade 400. The DX6i is such a pain to program that I decided to switch both the 400 and 500 over to my 9303. The blade 400 flies perfect, no issues. However, the 500 was a disaster! I luckily did not wreck the heli, as I never got it off the ground. The tail was ossilating so bad it sucked. And yes I adjusted the gain with no benefit. Also the the motor would just cut out, then the cyclic servo's would keel over hard right. One time the blades went into the snow. Glad that there is 2" of compact snow under my heli. No damage.
Decided to take the heli home and change out the esc to a phoenix 60 with a castle bec. The glitches were so bad that if you spooled up the heli on the bench, without blades, the cyclic servo's would all twitch the moment you started to spool up the motor. So I decided to change the RX. Put in a AR7000 instead of the 6200. Same issue. If I pulled the main RX out of the heli from the RX mount and left it dangle behind the heli the glitches did go away for the most part. Now here is the funny thing. Tailgunner called me and said to try some silicone lube on my tail belt and see what it did. I did two things, I tightened the tail belt, put rx back on tray, glitches seemed to go away. Then I sprayed a liberal of some dry lube with silicone on the belt while turning the main gear so the entire belt got coated. Again spooled up the heli. No glitches. In fact I went outside in the dark and spooled it up and hovered it. Here is the scarry thought. Does this mean that one would have to spray the belt every time before flying this heli? I have never and I repeat "NEVER" had to spray any of my other belt driven heli's tail belts before. Not even my other trex 600n's. I wonder if Align went to a different composit on their belts for the 500, which is causing all of the issues.
Question: has anyone mounted their RX up front under the battery tray? If so have they had any of these glitch issues?? Would moving the RX and remote RX away from the back of the heli help? I think I may try, but then you get the Rx closer to the motor.. Of course my Swift has the rx in front right in front of the motor with no issues. Also should I go back to the Align ESC? I would rather prefer using the stock componets that this heli came with. Otherwise why buy it other than it is the newest and hottest heli out from Align. Has Align had any comments on these issues to date? Would a torque tube drive system fix these issues. Is the brown out issues also being caused by a build up of static from the belt that all of a sudden disscharges and swamps the RX???? It would seem likely to be possible considdering what I have seen. I would hate to have to shelve this heli untill a fix comes out. I like all of the Align products that I have had.
Three other small issues with my 500 build. First off the flybar was bent in the kit. I had an extra pack of spares so I used a new one.
Second, the flybar rubbed against the inside of the head block when installed into the seesaw holder. I had to file down the inside of the head to get the flybar to clear when you teetered the seesaw with the flybar installed. Otherwise the flybar would rub and drag on the head block.
Third: The flybar cage had a bolt cross threaded from the factory. When I tried to take the bolt out to assemble the cage the bolt would not come out. I had to pull while un-threading the bolt. You could see alum in the threads. Simple fix, just get a longer 2mm bolt and cut to longer length and thread past damaged threads. Use red locktite for now. I will get a new flybar cage and fix properly later. Just want to get this thing flying first.
Here is my current setup:
JR9303 2.4ghz tx
AR6200
JR 500T\3400g
HS-225mg (cyclic)
Stock motor and ESC
Changed to:
JR9303
AR7000
CC-60 w\castle bec
I am not complaining as I really like this heli. It is the perfect size. But when you spend the money that this thing costs you would expect it to at least fly without all of the problems that a bunch of are having. I do not think that we all are that incompitent on our setup. Some are flying and crashing, others are having issues on the bench. What is the answer? Should most of us waited untill all the bugs were worked out. Did JK and Alan Z. have any of these issues when they were working on this project???? What are those that are having no issues doing different than those of us that are having problems?????? Comments are welcome.......

thanks for letting me rave.....

I'm very sorry to hear about your problems. My experience has been just the opposite.

My kit was fine and went together in a single day, with no problems. I use a DX7 with the 6200 Rx, Castle 60 Phoenix, Hi Tech 5245MG servos, and a Futaba 401/9257 for T/R control. The only difference is you are using a Castle BEC and I use the Align 3 amp regulator with a separate Rx battery (2s1500 TP).

The only issues we have seen with the DSS radios around here stem mainly from input voltage to the radio. I used to use a UBEC, but it crapped out, so I went with the separate VR/Rx battery and have not had any problems in my three big electric helis (Lepton, Trex 600, and Trex 500). Yes, there is that extra little battery to carry, but I would rather have a solid RF link than worry about a couple extra ounces.

Hang in there. The 500 is really a sweet kick a$$ heli. It's rapidly become my fave.

Hope everything gets better for you,

Ron

My buddy tailgunner disconnected the Bec portion of the stock esc and installed a RX battery. Still had the same glitch issues untill he sprayed the belt. I guess all this would be fine if you could figure how often you had to lube the belt??? I have a couple of the Align 3A bec and could use the stock 2s 1900 that came with. But I am not sure if that would help the issue. Tailgunner thinks that we should not make any other changes untill we can get the glitchs back and then start to make changes. How long untill the silacone spray wears off? I do know that when I pulled the rx out of the frames and had it dangle below the skids the glitch went away for the most part. It was not untill tailgunner called me and told me about the spray that I put the rx back in and the glitch was bad as normal and when I sprayed the belt it went away, enough that I hovered the heli for the second time..
Now what is going on in my mind is why did it fly ok with the DX6i but all of a sudder had a problem with the 9303?? The only other thing is that I changed the programming in the esc. Even put that back the the same as tailgunner with no improvement. Like I said I purchased this because the Align quality that I was used to. This is supposed to be fun not a pain....... Plus what about all of those that are experiencing the financial loss from the dreaded "brown out crash".. I for one do not want to join their ranks.
Thank you for your comment. I may dissassemble the tail and clean it to see if I can reproduce the issue. Then start moving stuff as tailgunner suggested. Just hate to spend all this time...

I noticed that some of the replies from this site and other sites that the glitch/lockups happen from the beginning and some occurs after 3 to 7 flights. I wonder if the weather, humidity etc contributes to it.

I did ground the tail boom tube but I don't have the metal tail unit to ground it as well. That didn't do anything!and I did check for continuity between boom and motor mount. Is there another method that you would recommend for those that don't have or don't want the metal tail pieces?
I personally don't have a problem getting one, I just don't have it now and my impatient A** want's to fly the thing without worry. Besides this should not even be an issue.

I just made 2-7 min flights after the belt lube with no glitch.
When the spray wears off as it did the first time I thought I fixed it, and it starts glitching again. I will try and move receive to front. At least when mine does it it just hiccups but my friends is not flyable when his does it??

I would sure think these MFG of helis would engineer grounding into their kits. I'm starting to think there is a conspiracy here you know more crashes means more parts sold bottom line = more money

I questioned this in the post about this problem . Since static seems to be the issue I would assume the atmospheric conditions would play a role in the severity of the issue.

The problem is static building up on the belt. You need to get a ground to either or both of the pulleys the belt runs on. I posted what I did in the other thread.

I grounded both but if you do one I would do the front one.

Its really strange that this problem didn't occur on my Trex600. However I have noticed that the tail boom braced that the Trex600 has alum. ends as well as alum. stabilizer lower mount that sits below the tail boom. I wonder if that was good ground on the Trex600 that is why it never occurred on the big bird.

"Is there another method that you would recommend for those that don't have or don't want the metal tail pieces?"

Cut a length of small diameter copper from an already small gauge stranded wire bundle. Aluminum or carbon boom, scratch up a section where it is hidden inside the tail case. Slide the case over the wire and onto the boom. Fold the wire back and loop it around the tail shaft. Some shafts have a black finish that should be polished down to the silver of bare metal. Depending on how much pressure the bent wire is rubbing against the tail shaft with, will affect how long the copper lasts before wearing through. There is nothing standard about this solution, but with a maybe 1 in 1,000 problem heli where all other good troubleshooting methods and resolutions have been tried, it can and has worked (I have done it for others).

"atmospheric conditions"

There are more than a few egocentric mechanical geniuses who occasionally lower themselves to post on this forum, that are more than willing to expound on the absolute lack of need to worry about any belt generated static issues, but only if you know how to properly build and prepare the model for flight.

When the humidity gets down around 20%, I have seen static become an issue when there had not been any problems for many previous flights. With tissue paper or very small (1/8"-1/16) pieces of styrofoam, it is very easy to demonstrate over the length of a boom, what low humidity and/or a 'dry' belt can cause.

widowmaker sre you grounding yours because you have had this issue or just because you think it should be done?

If I understand what you are doing is to place foil between the barring and the barring clamp then to the boom and that to the frame or motor mount. Maybe a pic would clear thing up. Just grounding the boom to the motor mount didnt do a thing.

I had a lockout, a sudden pitch forward in hover and a tail twitch. I should have taken pics first but Im just not in the mood to take my heli apart for the pics right now.

Not everyone is having this problem but most reported are with 2.4 including futaba, JR and Spektrum.

The problem these guys are having sounds extreme compared to others so Im guessing since they are both in the same location it may be atmosphere contributing to more static than usual.

I thought all the ones that I have seen so far have been using a dx7 or a 9303 2.4. Can you post a link to someone using futaba with the lockout on a 500? Never heard of being able to lockout 2.4 before this heli.

Its not a lock out or brown out in our case. seems to just cause servos to glitch/jump mine is more of a split second hiccup armsmasters is unflyable. we can both stop the problem with belt lube but as soon as it drys it starts again. I have been running flights on mine today waiting for it to start again so I can try widowmakers suggestion. It doesnt seem to make any sense to change thing while its working. or I don't know if fix worked. I do think this issue is made worse by our cold/dry climate, its 22deg today clear and lots of snow on on the ground. very low humidity static heaven
