I have a 4 cell Gtb speedo with a brushless motor. It has worked fine until I recently upgraded to The spektrum dx 3.0 with sr3000 reciever. Now it idles at a slow spin(with the radio off) with the radio on of course I can trim the throttle setting on the radio and once its on it stops. The radio responds well no glitches at all. So my question, is there a way to adjust the speedo to not do that or does that happen normally with the spektrum. It did not do that until the radio/reciever change. I tried reseting and changing profiles but it idles a tad faster everytime, would the drag brake adjustment help or hurt the situation or should I just deal with it cause after all radio should be on before car anyway thanks in advance for any advice

Sounds more like you need to rebind the spektrum radio and reciever. You might of had the throttle pushed a little when you set it. With the radio off it should go into your failsafe setting.

I rebinded it 3 times with same result thanks for the reply though

did you set the radio to the speedo after binding?

Sorry Dave dont quite understand your question. Im sure your on to something I have made no radio adjustments other than setting throttle/steering trim is there another radio setting I have to do? I got total control with radio just the free spinning of motor when radio's off thanks in advance Im sure if anyone can help you can

Maybe the use the "one-touch programing button" and re-set the speedo. Change all the setting to natural setting before doing so.

yes exactly put all the radio trims and subtrims back to zero and redo the one touch setup. this calibrates the radio's throttle to the speedo throttle.

Everything on the radio is factory default zeros and I followed the setting per novak on the gtb I re-binded them and re one touched still same proble

free spinning of motor when radio's off

My son commented to me that his was doing this also then later called back and said that it only did it when it was under his flourescent work bench lamp.
Interesting.

Sounds like you need to rebind the spektrum system. I've seen where some people have to do it a few times. Make sure you are not touching the trigger at all when you do it. I usually set it to full brake and slight left turn. When you turn the radio off or if the reciever doesn't sense a signal from your transmitter, it goes to the preset fail safe mode.

..I think he's said he's "RE-BOUND" several times now.

I have this happen quite a bit w/ the older SPEKTRUM receivers, and rebinding works for that...I move receivers from Car to Car and generally rebind them and reset the ESC's for every car (needed or not)

I'll be watching to see if he finds the Cure~

I have done everything I will take my car outside tonight I have had weird things happen to me indoors An i will reset my esc for the third timne and rebind for the 5th time

Novak tech support and the engineers would be willing to try to help solve problems related to the Novak items.

Charlie is in Japan at the Worlds, but you can e-mail steve@teamnovak.com for advice.

Sounds Like The Dead Band Needs To Be Changed In The Speedo. I Can Set Both My Up With The Same Number And One Will Act Like That. Go Up A Couple Points In That And See If It Helps

Sounds about what I was comming up with thanks

Thanks IM sure its not Novaks problem just me reading directions lol

Tim,

If you use the same radio but use the old style receiver...does it do the spooling up then too?

Nope not at all o thats called spooling cool see I learned something:woohoo:

Is this your car and you are have Tim working on it? Plus brushless? OMG Willie going brushless....who can I borrow a stock brushed motor from now? Hope you guys figure it out. I'm very interested on what you all did.

Lol it me had his screen name on adjusting his car. I tried dead band setting and all setting I got something to try here in a second

Thanks for all your replies after two more rebinding's and totally fine tuning the advance options on the speedo all is well man I love the gtb

do you even race? muhahahahahah

Question for the brushless guru's: My car/GTB is all set up for a 17.5 basic quick setup profile#1.. If i decide to drop in a 13.5 do I need to Re-setup? can i just drop in the 13.5 and Go? This is of course assuming I wanted to run the same profile etc. I know squat about these new-fangled brushless motors. Going to spend a few hours and tune/dyno/re-build a half dozen brushed motors tonite, I wont miss that!

You don't need to do anything but swap the motor! Set the speedo to no drag brake. :thumbsup:

Maybe gearing.

yeah definately need a gear change! lmao

what happens when someone uses, a GTB 4 cell NON SPEKTRUM esc but has SPEKTRUM in his radio? Does it cause glitches?There was a racer this past sunday who asked me and I assume if you have SPEKTRUM you would need the SPEKTRUM version. True or not?

i use a spektrum radio and a non spectrum gtb and it works grrrrrrrrrrrrrrrrreat!

does it still pertain to the newest version of the gtb's though? i know you said you have the older style.

The Spektrum version can be run only with Spektrum(2.4 dsm systems) and the regular GTB is for either.

Spektrum version is supposed to be a little cooler running I believe.

Has anyone used a spread spektrum 4 cell without a spektrum radio? Ive had some real problems with my spektrum equipment. About 2 minutes into the race, it decides to right turn.. It has done this every race. Ive been using the capacitor on the reciever. I also took off the brake cap. Could this be the problem? Someone also told me the high torque servo is draining power?

Jenzo, check the Novak Website, I think that they say you should only run the spectrum speedcontrol with the spectrum radio.

Jenzo,
It sounds like your Spectrum system is going into fail safe mode. Have you tried running a receiver pack?

A friend had a problem like that and he sent the module off to Spektrum and they fixed it.

I dont know if he was running a receiver pack or not, all I know is they think people where turning there radios on the exact same time as he was to cause radio interference but if he has spektrum how could that be?,lol but I was asked at the time if you could use a non spektrum gtb with spektrum radio because they were getting hits and glitches. Most of us have spektrum so even if we were to turn our radios on it wouldnt go to there channel. To me it has to be some sort of problem with either the system they received or how it was setup unless your not suppose to use non spektrum gtb esc with a spektrum controller.

Well, I had a similar problem with a Tekin G11. It was fine for the first two or so minutes, then it would loose all power. After sitting for 5 or 10 seconds, it would go again. Put in a receiver pack, and it fixed it. If I didn't charge the receiver pack at least every other round, it would happen again. I know there may be a difference in brushed verses brushless, but it's worth a try.

Try this, when you bind it, bind it with full brake and with the wheel turned all of the way to the left (I think thats how you do it, at least on my old Spectrum radio it was). When it happens again, if the car turns full left and hard brakes, then it's the fail safe kicking in.

From Novak's site:
HIGH-SPEED SWITCHMOSFET switching speed is a key feature for the spread spectrum specific GTBs. The MOSFET switching speed is not just the frequency of the ESC, it’s actually how fast the ESC’s MOSFETs turn on and off. With regular radios, ESCs are limited by how fast they switch on and off. If it switches too fast, the radio system will experience interference. With spread spectrum technology this is not an issue. Novak Engineers have been able to take full advantage of this great new technology and now offer a high-speed switching GTB for all spread spectrum users. While users should not expect a huge difference in feel or driving style, they will notice improved motor operation and lower ESC operating temperatures.

and


Please note, the #1711 GTB Spread Spectrum Brushless/Brush ESC and the #1715 GTB 4-Cell Spread Spectrum Brushless/Brush ESC are for use only with Spread Spectrum radio systems (2.4GHz radio systems).

Thanks Gezer2u, that's what I thought I had read.

Thanks guys. Im hoping sonny brown has a module with him tomorrow. It acted like it was going into failsafe. But i bind it with the steering to the left. Brake capacitor hmmmmmmmm???? And everyone i was racing with was using spektrum. And we all turned them on about the same time.

1 good wreck can ruin a reciever. maybe just try a new one?
