If anyone has any kind of problems with their SPEKTRUM Systems I STRONGLY suggest you contact:


JOHN ADAMS ([email protected])


As his e-mail address shows, he works for Horizon Hobby and specifically fixes and repairs all SPEKTRUM products as I believe he is one of the developers of the System! I got a number of 1st generation SPEKTRUM Transceivers and though I never experienced any serious problems, I sent them in for some extra peace of mind. All of them got the programming updates needed and I got them back in less than 10 days from Illinois to California - Talk about fantastic turnaround time!

Trust me, JOHN will take care of you! Don't bother doing it any other way if you are experiencing problems! You can now also e-mail him the Transceiver's I.D. Number to find out if you have a 1st generation Transceiver or a reprogrammed one. All you need to do is open the Transceiver and give him the Number on the inside (which is on the back of the circuit board). I have done this as well and got a quick reply back saying the two latest Transceivers I bought had the new programming. Best of luck to everyone and hope this helps!

Two times I did have a glitch for a few seconds. The first time my car went into a fail save. Slowed down, almost stopped, and steering wasn't possible. But after problably 5 seconds, everything worked fine again. The second time also no steering was possible, and car slowed down and stopped. But when I turned the transmitter off and on, everything worked fine again. In a race you don't want the fail safe mode (just as terrible as a glitch). Alone on the track, with no Spektrum systems on no problems at all.

I have driven now about 50 battery packs with Spektrum system in my M8, GP3300's and GP3700's.

Stuff I drive:
- Corally RDX
- MMS 3 (KO VFS-1) with high KO CAP and standard profile
- KO PDS-2143
- Corally Black 12x1 or 12x2
- AMB pt

Also using a 4700 uF 25V CAP to the receiver.

Problems did happen on the track with 3 to 4 other Spektrum users. Could there be more problems if lets say 10 drivers use it. My local track also uses a wireless network on 2.4Ghz for internet. But I don't have as much glitches as on 40Mhz. But failsafe or glitch is the same bad thing for me.

Hey I have a question?

what Spektrum unit do you use with the JR z1

would you use the JR system

or

The KO Helios system?

Use the KO Helios system - works great

I've had my Spektrum system since it was available for the JR R-1 and I enjoyed trouble free operation throughout most of the season (I have one of the newest - non updated systems). I did run into an odd problem 3-4 months later, where the system would go to fail-safe mode out of the blue (nitro on-road). What I found after I changed receiver battery packs is the problem went away, completely. Upon inspection of the battery pack that was causing the fail-safe mode, I found that one of the soldered tabs was loose or broke away from the pack. My guess is the "intermitentat(sp)" loss of power would not be noticed to a normal FM system, if noticed it would appear as a small glitch or "intereference", however, to Spektrum it takes a few seconds longer to "bind".

Once I resoldered the pack, and I haven't had a problem since!

ok guys, i know the M11 Module has extra pins...and you have to drill or buy a new spektrum module with the updated holes....but my questions are the Spektrum receivers(SR3000) compatible with the new M11. is the only difference in the module for the m11?

I've got a module for sale here in the swaps!! Its for a Helios, Mars and MarsR.

Ray

receivers are not TX specific.... they r generic i.e spektrum only makes 1 type of Receiver

e.g if i have a m8 spectrum system in my car, then if my friend wanted to have a go on my car, but he wants to use his own spektrum helios, then i wont have to change my Receiver, he just uses his Helios.

Hopefully, he binds them first...

yeah i didnt want to use that word, coz then hes going to ask "what is bind" ...

I have a question that's probably been asked before...I have aQC2..with a Spektrum system. When I plug in my JR4750...it goes crazy. When I hook up my 590mg..it's fine. Will the cap fix cure this??

To those that loose frequency of their car if they're more than 30-50 ft away, I believe I have solved the problem (at least in my case).

Check out my solutions in this thread. Hopefully it'll help a few of you guys out there with similar problems as I have encountered.

Does anyone have a link to some pics of the telemetry module for Spektrum?
