Are these problems more so in the Optic 6, or are they just as common in the Eclipse 7?



I can't answer definitively as to the universe of users having this problem, but it seems from the posts in this thread alone that the problems appear equally in both transmitters. That is likely due to the fact that the same identical Spectra module is used in both transmitters. Further, it is not clear to me which of the production runs of Spectra modules prior to or after the "507" batch are experiencing this problem. It may be that only the modules produced within a certain time period are evidencing this phenomena.

Having said this, and observing no complaints from Optic/Eclipse users with single frequency RF modules, I now reverse my opinion that the problem is inside the transmitter unit itself - the problem appears to be isolated to either the Spectra module itself or the interface of the Spectra module with the transmitter unit. There are more questions than answers in evidence at this point.

Grace and peace,

Pastor Mike

Status: offline 		I wish I would of looked here first when my Optic 6 started glitching. After visiting the Hitec forum and finding postings on this very same problem I took my TX and module back to Hitec this afternoon and dropped it off. Behind the counter where alot of packages coming and going. My Optic 6 started glitching a few weeks ago and alot of heli parts later I descovered that my TX was the cause. At first I thought no way is this awesome radio the problem, but I was wrong after trying another radio and NO glitching. I looked at the DX6 but there some bad reviews on it ,so I put my radio in the hands of the techs at Hitec and from what I hear they have great customer service. I believe that they should be replacing with new parts. Good luck to the crew at Hitec on this one. I still like there products.

I really like my Optic 6 and will use it again, But I do think they need to do a recall for safty reasons, somebody can be seriously injured or killed by a outta control heli or plane and blaming it on pilot error may not hold up in court now that the problem is public.

When someone gets seriously hurt, or worse yet, killed because of a known issue with the Spectra, Hitec won't be able to hire enough lawyers in a lifetime to defend themselves. There are enough idiots in the world just looking for a way to start a lawsuit, I think Hitec has left themselves wide open. This is obviously not an isolated problem, it's well documented all over the internet.

Status: offline 		Update:
After running ground tests ad infinitum/ad nauseum (or so it seemed), I finally took that deep breath and flew my plane. I had absolutely no problems whatsoever, and to all appearances things are back to "normal" as they existed when I first purchased my Eclipse 7-channel transmitter. I'm not at the comfort zone to where I'm throwing caution to the wind, but with time I'll probably regain that sense of utter confidence I once had.

Kudos again to Hitec Customer Service for the extremely short turn around time in servicing my transmitter and returning it to me. I do appreciate the world-class performance.

To Mike Mayberry: I appreciate your services on this thread. I do realize that the point of the spear in customer service can get a little hairy sometimes. You showed a remarkable calm and consistency in responding to our frustrations. I apologize for having 'vented' as I did. Keep up the good work!!

AND ... in departing, here is just a brief bit of scripture twisting with this quote for Glenn and Terry: "God has not given us a Spectra to fear, but of Power, and of fun, and of sound flying." (2 Tim. 1:7, twisted by me) The views and opinions ... blah, blah, blah [Previous disclaimer repeated]

Grace and peace,

I'm really happy with the fast turn around time at Hitec .I dropped mine off on Monday and it it was finished on Thursday in time for some flying this weekend. I will post back if I have any issues later.

Status: offline 		Hi Guys,

I am about to begin using my Optic 6 again. How else will I know if it is truly fixed? I have a few SPAD combat planes that are easily replaced should they crash so I will start with them. While I have really, really enjoyed flying glitch free using the DX6, I have missed some of the features that the Optic 6 offers that the DX6 doesn't.

It will be nice to know if it truly is the newer modules that are the problem. I must have a dozen or more, FM receivers to use with the Optic 6. If it is the newer modules, I can't for the life of me understand why Hitec is not recalling them and replacing them. Perhaps they don't know why they are failing, and only have a few of the older ones to give out. I sure hope someone doesn't get seriously hurt while they are figuring this out.

Blessings, Terry

I'm sure we will all be happy again when we know that our problem has finally been resolved.

Status: offline 		My Optic 6 still has no glitches , but the tape fix Hitec did just made it harder to remove the module to change channels. After a few times the tape just gets ruined of corse, and then you got to re-tape it. Not a good fix at all....

Status: offline 		I have to say that I don't believe that the tape is the answer. Side to side movement of only the thickness of a piece of electrical tape is very unlikely to be the cause when the pins actually penetrate almost 1/2" into the module. This has got to be caused by faulty modules. The only reason that I can see that Hitec is not recalling these modules is that they don't have a real "fix" for this problem other than replacing them with "older" modules and they must have a limited supply of older modules. They sent older modules back with mine and I can still fit a piece of tape on the side, so if they are actually larger than the newer modules, it is not by much, if at all. I sure hope no one get hurt before this is finally taken seriously enough to see a real fix for this problem.

Blessings, Terry

I personally don't mind the tape, as I don't change channels anyway, but I can see from a different perspective that the tape fix could be very annoying for someone who does.

Status: offline 		I tried out one of my Optic 6's this weekend in a Charger RC Shockwave Bipe. I flew it about 6 times and didn't experience any glitches. This is how it was when I first bought the radio. i guess time will tell if the glitching will start again after some time. I will continue to use them in some foamies to see if the problem returns. I opted against my original idea of using them in a combat plane. The foamies are a lot less dangerous should they go out of control.

Status: offline 		I was flying my planes on Sat morning and all was well until I started flying my Trex Heli and after 5min it started glitching I was about done with my Optic 6. But after spending time locating the glitch I descovered my CC35 ESC was the problem. I moved the ECS to the opposite end of the RX and it seemed to fix 90% of the glitching and after finding postings on the net from people having the same problem with the CC35.

In short, I'm DONE WITH 72MHZ, It has cost me countless hours of trouble shoting, web searching and Money, So hello DX6 2.4GHZ good by 72.

Now the only problem now that I have the DX6 is it's not as good (IMO) as the Optic 6 when it comes to controls and features . The DX6 also seems to lag when using CCPM controls and the TX body is kinda "toy-like".

So I decided I needed the best of both worlds by Spektrumizing the Optic 6 like done here. http://www.rcgroups.com/forums/showthread.php?t=489403
After spending the evening reading this thread all the way through and I'm sold and doing the Mod right now and it's even easier then I expected.

Status: offline 		I just completed my OpticDX6 mod and I am really happy with it. Took me 2 hours to complete. I did my wiring with servo plugs on the inside so I can swap the 2.4GHZ module back in forth from the DX6 to the Optic6. This allows me to put the radios back to there stock set up so I can still use the Optic 6 for 72mhz stuff I still fly until I can get more AR6000 RX. The only problem I had was forgetting to put the RX servo's in place where a Hitec RX would be(ch1,ch2,etc) at first I had it set for the DX6.Once I got that handle I got in some flight time with my Trex and I love the fact I keep all my memory settings. :

I may just do that today. I have to imagine that this mod will void the warrenty on both radios though. Oh well, fo a glitch free Optic 6 it will be worth it.

When new they fit very well but with a few uses
the wear gets to the female connectors and then
we get the intermittant operation. If the tape is

I tightened the plugs and the glitch went away.

I believe that one of the folks here claimed that he only used one frequency and didn't ever remove his module. You may be right about the connection being faulty, but it is more likely poor connectors if they go bad without even being unplugged/plugged. Besides, what is the sense in buying an adjustable module if you can't take it out to adjust it? If they had been smart and put the pots on the back of the module so you could adjust it without removing it they may have less problems here.

I flew my Trex 6 times yesterday and I really like my new set up (not a single glitch). It will void your warrenty. I also put my 72MHZ module back in, and it to still works fine for my plane stuff.

I think Hitec would have been better off if the allowed you to change freq. channels without removing the module. IMO pulling the module on in off is causing the contacts to wear out, and thats whats causing alot of the problems. Maybe Hitec should put the pots on the outside so you don't have to remove it or just have it built in with a port for there 5.8GHZ module when ever it gets released.

Status: offline 		Hello all, I have an OPTIC 6 with the SPECTRA module date code of 510. It glitches terribly some times, and can be made to glitch by pressing / wiggling the module in the transmitter while in use. The guy at the LHS said to trim the case on the top where the modue locks in, but I didn't want to try that.
Can someone please post a picture of where to put the "electrical tape" to try this fix.
Also someone mentioned "tightening" the contacts in the module, any pics or description of how to do this?

I really enjoy flying with this radio, but the glitches are NOT ACCEPTABLE!

Any further information for the Hitec Rep?

If I were you I would send it in and let Hitec give you another module. From my experience it is only going to get worse until you start losing control of you planes altogether. I have two of them and they both started were yours is at and steadly got worse. Don't lose any planes like I did before you get this fixed.

Status: offline 		Terry: You're right. The transmitter and Spectra module should be sent back to Hitec. The modules that Hitec is replacing in the system when the transmitter and Spectra module are sent to them for "repair"' appear to be older versions of the Spectra, and they ARE somewhat (and visibly) used, but they do work with none of the erratic and highly distressing glitches that I was experiencing with my original module. In short, sending the unit back and receiving a replacement Spectra module is WELL WORTH the investment.

It DOES seem to me the guys at Hitec are getting somewhat of a free ride because the cost(s) associated with shipping a WARRANTED transmitter back to them should not be borne by the users, but that's obviously not going to change. Or, they should OFFER something of value to us.

OBTW: I was out today with my U-CAN-DO- 3D for the first time since these troubles began, and the transmitter performed flawlessly.

After sending my TX back to Hitec 2 times for repair, the problem has started all over again on the fourth flying session. It worked without hitch until yesterday, and the major glitching started over again in mid-air. This problem is not solved with a replacement module. I was lucky to get my plane back on the ground with only minor damage, without a major crash.

Hitec, PLEASE HELP !!! This problem is not going to solve itself.

I'm glad you were able to recover your plane with only "minor" damage." I was already in the "observation/evaluation" mode with my Eclipse transmitter after having the Spectra module replaced by Hitec Customer Service. Hearing of your most recent incident, I'm going to stay in that mode for a long time because I was never totally satisfied with the mere replacement of the Spectra module. One (or more) of my speculations about the entire system is probably closer to the truth concerning the glitching issue we've been discussing.

To ALL: I will grant that Hitec owes us a continued focus on this issue AND they owe us an ultimate resolution, but let's not deceive ourselves - WE should exercise extreme caution and the utmost of attention to the slightest performance issues with these systems until a permanent solution is developed. Don't fly it if you are not absolutely comfortable with pulling the trigger on a flight. That is what I'm doing in my observe/evaluate mode!!

Grace and peace,

Pastor Mike
