Status: offline 		Update:

I called Hitec this morning, and they are shipping me a fixed frequency module. I'll be returning the defective Spectra. I don't have a problem with that solution because I never change frequencies anyway. If that solves my problem I'll be happy. Unfortunately for those of you who purchased the Spectra to change channels, it hasn't solved your issue. I'll continue to update after I receive the single channel module, and let you know how it goes.

BE VERY CAUTIOUS with the Spectra. As I mentioned in my above post, I was careful about what I flew with the temporary fix. It's a surprisingly funny sight trying to land a plane when the rudder and aileron servos are going full swing wild. (also some crazy aerobatics) It looked like a Z Z Z pattern when it finally landed on its' wing. It was a 3D foamy, so the damage was only superficial. A little hot glue, change the TX to the Flash 5, back to flying.

No major harm done this time..... but what if it were an 80mph gasser totally out of control?

Status: offline 		Wow, what a drag. I have installed a couple of 72mH RX in two of my foamies for evaluation. I was really hoping that the problem was fixed. I am still seriously considering swappin the Spektum board into my Optic 6 but I hate the idea that it will void the warrenty. The Optic 6 is waaay more versitile than the Spektrum but glitch free is sooooo nice. I know several guys who have converted JR 6102's over to Spektrum, but that is an almost perfect fit since JR makes the transmitter that Spektrum uses. I also only have 6 AR6000 Spektrum RX and they are already in planes. At $60 a pop, there is a limit to how many I can afford.

Blessings, Terry

The best fix it to return it and buy a Futaba.



I think you are right.

Mine is on the way back to Hitec service again for the 3rd time. After the last fix it worked perfect a few sessions, then went back to the same old glitching. Personally I don't think it's as much the movement in the case as it is when it heats up. Mine had the tape fix, but after flying for about 20 minutes it goes haywire again.

If Hitec would just keep it and refund me the purchase price I would happily go buy a Futaba.

Can you share with us more details of what you have done to put the Spektrum module into the Optic 6? I.E. the exact wiring, switches, etc. Closer pictures telling us what we are looking at would be nice too.

This sounds like a very interesting modification.

Cheers,

The second link gives the basic how to's that allow you to mod just about any radio to 2.4ghz. http://www.rcgroups.com/forums/showthread.php?t=489403 http://www.rcgroups.com/forums/showthread.php?t=458314

You would be best to ask Hitec about the fixed frequency module. They sent me one at my request and it didn't work at all. I sent it back to service along with the TX and Spectra module. See post # 56. You might have better luck.

Status: offline 		Well... I sure wish that I would have seen this thread before I purchased my Optic 6 last week.
I purchased a new Optic 6 to replace my Eclipse 7. I never had any problems with my Eclipse in over year.
Went to our local club's Cub fly in yesterday with my H9 J-3... and you guessed it, lost total control of the plane and it went in. No warning whatsoever. One minute I had the plane, the next minute it was gone. I thought for sure that it was a radio hit, and chalked it up to bad luck. When I got home, I checked the plane over to make sure it was not a mechanical or electrical problem and it was fine. Matter of fact everything worked fine after the crash. Needless to say, I was convinced that it was a radio hit. Plane is pretty much a total loss, but the important thing was no one was hurt.
For those of you who have never had this happen, I pray that you never have to experience this. It is a really helpless feeling when you have an 8 pound aircraft that you have lost control of, and all you can do is watch and pray that it goes down and does not hit anyone. Of course I am upset that about losing a $400 plus plane, but I am more relieved that an innocent bystander or personal property was not hurt. Our hobby is having a hard enough time keeping our flying sites as it is. It does not need a tragedy like this to hurt it even more.
Anyhow, I decided to take my Super Chipmunk out today. The Cub was on channel 23, and the Chip on 31. Each plane had a different receiver. I did an extensive grond check of the plane, and a thorough range check. Everything checked out. First flight went off without a problem. Second flight out, not so good. One minute the plane was there, the next I had no control. Boom! Into the ground. Sooo... I packed up and came home and decided to cehck out RCU and here I am.
Now, I have been a Hitec user from day one. Great product at a good price. But from what I have seen from this thread, my case is not an isolated incident. Yet, Hitec is acknowledging a problem with this radio. But, they are not recalling the product, nor are they giving a new owner a heads up on this. Unfortunately, Hitec needs to realize a few things. Not everyone in this hobby would think to check RCU to determine if the product they wish to purchase is glitch free. Secondly, Hitec needs to pull this product before some one is hurt. At the very least, place a note in the packaging to warn of this potential problem. As for me, I am out two planes, and have a radio that I can not use. From what I have read, the tape fix that Hitec is offering is not the cure.
As consumers, what do we do? I am sure Hitec is not willing to reimburse me for my planes and equipment. Nor do I feel that I should trust another plane to this radio, electrical tape fix or not.
What say you Hitec?
Regards,
Rob

Sorry for the loss of your planes. I have been a little more fortunate than you, because having discovered this issue within 60 days of purchasing my radio, I only used it for foamies, and the losses haven't been quite as expensive.

We haven't heard from Hitec since post # 9. Not much to report I guess.

The standard response is send it in for checkout, which I've done 3 times now. My TX is currently at Hitec service as I write.

I've been a loyal customer of Hitec for over 5 years, and own a lot of their servos, receivers, and 2 other TX's, but this Optic 6 thing has left a very sour taste.

As consumers we need to spread the word about the problems with Hitec and there tape fix. Tha manager at Hobby People say's he's contacting the main office to see about stopping there sales of the Optic 6. I think all HS should follow.

Great, now there will be even more planes in the air just waiting for a chance to go out of control and hit something or someone. Come on Hitech, show us you do care about this problem. It is not going to go away by itself.

a bad investment.

Status: offline 		I received a brand new Optic 6 along with a new Spectra and also a fixed frequency module from Hitec yesterday. I have not yet tried the Spectra module (it has the older date code), but the fixed frequency module works perfect. Not even a hint of a glitch, chirp, or peep.

I'll try the new Spectra module soon, and report back.

My faith has been restored in Hitec service. Now if the new radio works as it's supposed to I'll be a happy camper again.

Status: offline 		Damn, I spent quite a while writing a post and RCU dropped it.

Well here is the shorter version of what I wrote.

I feel the problem is related to the module connection to the TX. The pins and socket. Why?

In my case I fist bought a Optic 6 and after a short while had the glitiching problem, albeit, when I moved the module and so far not during flight. I sent that in and at the same time bought a eclipse 7 and supreme 8 receiver. Intitaly I did not experience the problem on the Eclipse, but then it happened. Not the way you might think.

I had installed a 2500Mah Ni-Mh battery and on the bench had been messing with this module glitch thing when all of a sudden the TX says "Low Batt" and then the back of the case near the battery compartment started to smoke. I switched it off, pulled the freaking hot battery out and stepped back. keep in mind this all took place in less than thirty seconds.

Well after letting things cool down, I finaly cut away the HS on the battery pack and physicaly inspected it, all OK except the toasted wiires. I then performed several cycles on a triton to check it's capacity and performance, all was well.

Next I pulled the burnt wiring from the TX, bypassed the charge jack and reconnected the power connector direct to the board.

Since then I have not had another issure with the shorting out, but can still get this radio to glitch almost on command. I have to take great care in handling the radio if I want to fly with it.

So what i think is going on is the contacts between the module and the TX are the culrpit. Mind you I have read all of the posts, especialy the detailed post about how all this works, with great respect.

I am going to attempt to prove the connection issue by trying the follwing tests.
Create a jumper set that has standard pins that will fit into the socket of the module and female connectors that will attach to the pins in the radio.

next with out disturbing in any way the pin contact in the module, minipulate the module case to see if any thing happens. If not then I would rule out the actual module with the exception of the pin socket.

Next try moving the pins in the module, one at a time and several at a time. I think this is wear the problem will come from.

If not then the next would be to start manipulating the pins on the TX.

It has to occur from one of these tests or at least I think so.


I'll post up in the next day or two my findings.

Mike R

Status: offline 		Well folks, before I can comment on the testing I found a propblem IMO. See the attachments.
No.1 shows the female connector on the Module PC board. Notice that there is a very small gap between the board and the whit socket body, not much but a little.
No. 2 shows how much this gap increases as the pins are insterted into the socket.

Now this can't be good. for thoose of us taking the module in and out, we are causing that socket to move quite a bit and possibly cause a poor connection with a solder joint on or near that socket. As sensitive as this device is, that sureley could lead to a glitch.

I also noticed that the pins are gold plated and the sockets are not. Hmmmm? Also the actual contact area of the pin against the mating socket surface is only about a 1/16" on one side of the socket. . The 1/2" insertion amount means nothing here.

Well I have added a couple drops of thick CA to the base of the socket and letting it sit overnight to cure, No accelerator here.

Then I'll put it back together and see what happens.


Never could get the images to load on RCU so here are the links. Might want to right click and open in new window.

It's a good theory, but I never removed mine. My theory is that when the module heats up, it begins to glitch, because sometimes I could fly for 5 minutes without problem, then the glitching would begin and not stop.

Hitec sent me a new TX, a brand new Spectra module with the older date code, and a fixed frequency module. The fixed module works perfect, I haven't tried the Spectra yet.

I will keep that in mind. I performed the first test last night after securing the socket. It glitched imdiately by moving the module.
I did notice that it stayed cooler outside of it's plastic case.

I also made up the jumper by using three pins that were not gold plated and a slightly smaller diameter. took them from a power block on a PC motherboard.
Setup with the module sitting on the bench, and low and behold, for the test it was rock solid. I could not get it to glitch at all. I put twisitng forces all over the module and wiggled all the connectors.

So now that you mentioned the heat issue, I'll do the same and let it stay on for 15 minuets as well as wiggle things around.

so in my case, and possibly others out there, it is the connection to the module.

so the gold pins are coming out and standard pins are going in, I'll let you know.

Status: offline 		my module acted alot like glenclif's. seemed to work fine for a few minutes and then the glitching would start and slowly get worst the longer it remained on and tapping on it didn't make much differance. I tried the tape fix and that didn't work either so I sent it to Hitec where they put my same module in a older case with there 1/4" tape. That worked for 2 weeks but then again, it started glitching and now I won't use it. In my case the radio works fine with the DX6 mod, so I also believe the module's electronics is the main problem followed by the lame contacts.

Status: offline 		Time being aginst me here, I didn't get the pins changed out, but I did a quick experiment by going over the pins with a wire brush on my dremel.
removing the gold plating.

Put the module back in and it is now rock solid, no matter what forces I apply to the module.

I figure at this point for me, my issue is definetly the contacts. I let the radio sit for 32 minuets last night allowing the module to fully heat up and still had a solid signal.

Next I am going to try removing the plating on my optic 6 contact pins and see what effect it has.
