Question,
I was having a few concerns with a spektrum dsm3000, that I have paired up with a novak GTB and a 5.5 motor. Every once in a while the receiver will shut down under hard accel. You've probably heard that before right?
My question is, will the other dsm modules correct this low voltage problem? or is it a battery concern?

Put in the 4700 uF Spectrum Capacitor

Alltapdout -- John S. gave you the answer...(Hi John...)

Some esc's are a bit weak in the BEC circuits -- they are lower in voltage in general or they cannot maintain the volt/ampdraw capability when the motor draws high current levels. Using the GTB I haven't had any problems in my brushless rigs (13.5 and 4300), but with an old LRP V7.1/brushed setup, even a 19t motor can cause problems... One additional factor can be the steering servo -- some newer digital servos can really draw juice and add to the problem...

The receiver can't help it -- it either gets the juice or it doesn't. The capacitor rig smooths out the spikes and carries it over the voltage drops (sort of like a UPS for a computer to cope with brownouts)...

Yeah, see thats the thing. I've placed a novak cap on the radio already, not sure if I needed a spektrum cap? Never made any difference, when I come up for a jump, and nail it, the car receiver dies, car goes dead.

Antenna wire shortening on the SM3001rx, saw a tip once, but cant seem to be able to find it again.
Any help please.
Thanks, Fred

Its the antenna wire route. Spektrum wants you to route the antenna under the chip board, not over it. The tip is on there web site. Have already tried that one too. I did read though, that spektrum will take receiver back if it still glitches for a software upgrade? or replacement!! That might be what I have to do @ this point...Any other suggestions?

Futaba's system uses a different form of 2.4GHz called Frequency Hopping where the system hops from one frequency to another. Spektrum uses Direct Sequence which means it scans all the channels in the band, finds an open frequency, and locks onto it. This is just one of the reasons why Spektrum and FAAST equipment is not compatible with each other.

Your fastest option in terms of the quickest frame rate and lowest latency would be to go with the HRS Module Set found here:

When binding the SR3500 receiver, the LED should flash twice, pause for a moment, then begin rapidly flashing. At this point, push the bind button in on your radio or module, apply full brakes, and turn the radio on. This is how I set mine and it works great. If you're still having issues, verify that you have the polarity correct on your ESC/Battery. This will cause the receiver to not bind properly.

How old is the receiver? If it's more than a year old I would send it in to have the firmware updated. I run a GTB and brushless motors in my XXX-4 and SR3500 receiver without issue. There really haven't been any issues with Novak's BEC's and Spektrum equipment. If you are getting stuttering or it's going into failsafe, try the SPM1600 Power Cap. Also check to see that you don't have something else causing an unusual power drain. Make sure your servo wires insulation is in good shape and not shorting against each other, inspect your drivetrain for free movement, common sense stuff.

The receiver is definitly over a year old now! more like 3 I picked up a dx 2.0 as soon as I seen them in LHS. Its a dsm3000. I run it in a xxx-4 with a 5 turn. I called Novak and they told me it was a battery issue, I didn't really think that cuz I was using lipo's, and it did it on a full charge. Then the battery company told me it was the speed control. . Then I went to the LHS the owner said he has only seen it happen once, and recommended that I put a Glitch buster on the receiver. So I did that, Plus theres not a whole lotta room under the hood on a XXX!!! Plus what speed control needs 2 huge capacitors? I'll give it another shot later this week, but if it still stalls out, I may have to call spektrum about software.

This is an Horizon Spektrum(™) thread. You have an Futaba 3PM 2.4GHz FASST™ Spread Spectrum radio. Spektrum™ is an trademark of Horizon and has nothing to do with your radio except booth use 2.4GHz technology...

3PM 2.4GHz FASST™ is as fast, to my knowledge, as an 3PK/3VC radio with a Futaba 2.4GHz FASST™ module and R603FS or FF receiver.

R603FF and R603FS are basically the same receiver (same speed) but the R603FF is slightly cheaper then R603FS. R603FS has two dual-diversity antennas (one inside and one short external). The new R603FF has only the external antenna so its not dual diversity.

Hey guys i've been having a really strange problem with my spektrum receiver. It was working all fine last night and then today i just wanted to run the car, but now my receiver seemed to just gave up on me .
When i turn it on, the green LED would just blink on once and then just go out completely. I tried connecting to two different ESCs and still the same problem. I tried with and without capcitors and i even tried a separate battery pack...all the same, the light just blinks on once then goes out and stays out. I've never had a single problem with it until now I can't even rebind, becuase my receiver just doesn't stay on

Btw does opening and cleaning the receiver out void warranty? there is a quite a bit of junk inside, but i don't want to open and clean unless i'm sure its OK

Fixed it now After about 20 retries of fitting the wires together... its just suddenly worked

I wanted to shorten the ant wire, no prob with the routing.
Found the article in the owners manual, shorten ant wire to 3.6".
Amazing what you find in the manual, usually never opened until all else fails.

HPZ, make sure your transmitter module is pushed all the way in. I had the same problem and found out the TX module wasn't fully seated.

I am looking to purchase the dx3r, but i really dont like so much the steering wheel looking, could anybody tell if it is changeable to other brands optional wheel with its own wheel adapter or from other manufacturers, for example: sanwa, ko or futaba, but with some modification?

Thanks!

Gary--I know there have been several updates and fixes for the original 3000-series modules and receivers but has Spektrum/Horizon ever offered to upgrade these earlier units to "Pro" spec? Is that even possible?
