RE: I have several new erratic acting Hitec receivers, HELP ME PLEASE??

Ok, Alan, let it be "new Auto Gain" as it was referred to in October 2008 and still appears in the description of those
products, if it has to be that precise. In fact, I had read the source on...

RE: I have several new erratic acting Hitec receivers, HELP ME PLEASE??

Can somebody sensibly explain what Hitec means by its new "Auto gain" feature? AGC is a commonly well defined
notion, and taking it literally there are no receivers which would not have it. After...

The R606FS Futaba receiver problem

<span style="font-size: larger;">Finally I decided to install the 6EX 2.4GHz system bought a while ago from Tower Hobbies to a neat glider which retired into my hands after a pretty good career. I...

RE: Club Thunder Tiger?????

I'm not sure how would it look like when seizing. It used to be a few times when the (first) engine was very young that it stopped around the top dead point as if no compression were there and the...

RE: Club Thunder Tiger?????

That's right, but I'm not sure in my case this will be a conclusive test. I expect if I try the nitro fuel I will not have these problems for a while: indeed, based on the symptoms, it looks like...

RE: Club Thunder Tiger?????

No, I did not try. Somebody at the field said modern engines are designed for fuel with nitromethane, but the manual for GP states it can be run Ok with no nitro as well. Where we flew there is a...

RE: Club Thunder Tiger?????

I have the very same strange behavior with two of three GP-42 we have (the third one is simply still NYB probably, would show the same otherwise). Very pronounced! Yet the engine usually would not...

RE: HITEC servos & FASST receiver compatability

Mike, I read about this problem for the first time. Can you introduce me a bit with more detail? For I may need to use a 2.4GHz system until the problem with my Optic is resolved. Does this...

Update on Optic6 with spectra module?

I was subscribed to the thread on Optic with spectra module glitching, but it seemed to be closed and I did not hear news for a while. Now I got the very same problem when plugged a 72MHz Spectra...

RE: Hitec Supreme 8 receiver - malfunction

I am just afraid once I have had problems it would be a bit too late to send the receiver anywhere. For plain range check we don't send out; so I reckoned if I can do another simple test which...

RE: Hitec Supreme 8 receiver - malfunction

Mike,

What should be precisely the 2d het frequency in your receivers? I assumed 11.155MHz sharp. However I checked several of my Hitec receivers (Supremes and Electrons) and they seem to...

RE: Futaba crystal in a Hitec receiver

Finally I was able to play with a good spectrum analyzer and my
Hitec gear which in this case was Laser 4 TX and Supreme RX. I also
checked the GWS crystal sold for Futaba receivers (channel 22)....

RE: Hitec Supreme 8 receiver - malfunction

A good suggestion. However, walking with our TT Easy Trainer 40 with the engine running for half a mile is little pleasure (although I truly love it ). Besides, the receiver is very well packed into...

RE: Hitec Supreme 8 receiver - malfunction

Well, I own about ten Hitec receivers to be used if needed, in different locations. Sending them all to the Service would be impractical, let me put it this way, since I do not have a particular...

RE: Futaba crystal in a Hitec receiver

Thanks for clarifications. I have put Electron 6 together and
installed into my son's electric trainer while pulled out the
original Hitec HFD-08RD (aka RCD3500). In between we took close up

RE: Optic/Spectra Glitching

An update on dimensions. I looked closely at our `older' Spectra with the code
503. Its width is generally 37.5mm, varying though from as low as
37.1mm to 37.5mm along the side -- can be expected...

RE: Optic/Spectra Glitching

I am probably very naive, yet to be sure: is there any chance to simplify this procedure (on the case by case basis) if Hitec simply sends me the new half and I replace it myself? I can return the...

RE: Futaba crystal in a Hitec receiver

Thanks,

I more or less know the general facts, but failed to find the specific information. I believe both Hitec and Futaba use the 5th harmonics. So far,
however nobody answered me which...

RE: Modulation in FM?

Thanks for this "CFR 47", that is what I missed while googling.

Ok, I finally could get there the FCC rules formulations. Yet again no
more said than 8kHz of authorized bandwidth. That is a...

Can somebody clarify the modulation standards used in our RC in the

they specifying that "The authorized bandwidth for any...

RE: Optic/Spectra Glitching

Ok, now it's getting more clear. If that is how things evolved, it may make sense to replace the cover on our "early" Optic as well. I would prefer a tighter secure fit and am ready to sweat for a...

RE: Optic/Spectra Glitching

Trying to digest the information... Why it was decided to replace the
TX rear cover if it was the module size that went out of the original
specifications? Would not replacing the TX cover create...

She used the (metric ) caliper, an old one without dial. The reported width was 37.5 mm, to be precise. I'm pretty confident in that particular measurement since, to be sure, she asked our neighbor,...
