All receivers shipped since the early part of this year have the updated programming. If your receiver is less than 6mos old I wouldn't worry about it. The receivers in-stock and ones shipped since April-forward all have the new firmware. And no, the interface is stricktly for the receiver, not shared with any other divice and is not user-serviceable.

5-cell mini pack? Like a receiver pack? The issue is eliminated completely when you use a receiver pack because you're bypassing the BEC all together.

Fascinating. I will break out the the mini-cells and see what happens. Thanks.

wow!

I am very surprised by this thread.

62 pages 75% of the comments complaints and issues.

I had my mind made set that I was going to buy a DX2 or DX3.

Now I am reallly nervous about doing that!

Maybe not having to worry about a frequency tag isn't worth the known issues.

Well I don't know about you but I post and ask questions when somethings not working, I don't go looking for help for something that is working hehe :D
(and yes for record the spektrum is fine in my 1/18 brushless, 1/10th brushless, 1/10 nitro and 1/8 nitro).

Problems with people not turing off radios or running wrong crystals pushed me to 2.4Ghz.

The majority of the issues you are reading about are associated with esc's that have 5v for the BEC. If you make sure you use an esc that supplies 6v, you'll be just fine. I use a gt7 in my fko4 and a tamiya volac (ko rebadged) in my TA05 and have never had an issue. You'll love the response time of the dx's. I have the dx2 and love it!! Good luck mcgmark--Al

Well I just order the spektrum cap SPM1600, that will solve all my problems according to this thread and what I have heard around the pits. Get the radio, it's worth it. I run it with my Savage with zero problems. The only reason I am experiencing problems is because of the amp draw from the receiver, brushless motor and the fact that I am using a digital servo.

Get it dude! read my post about about 1 or 2 pages about anybody thinking about getting the system. These guys fix your S*** with no questions asked and before they say it will be done. That means allot. They stand by thier stuff and if you have any problems which I bet you wont they WILL and I mean WILL take care of it. Its makes a difference to me to know that. And remember I screwed that module up myself. No warranty!

Awsome I bought a GT7

I will most likely end up buying spektrum the idea of never having to wait for a frequency tag is worth giving the DX2 (or 3) a shot..

and the radio is a great price!

I have come accross a new problem with Spektrum.

Equipment:
RC12L4
Tekin G-10pro+
Spektrum SR3000 RX
Reedy Ti 10x2
KO 949
IB4200SHV
Futaba 3PK running standard spektrum module

Problem:
Some times when I turn the car on channel 1 and 2 seem to clash with each other. I turn on the car, and the servo will be like vibrating, and same with the motor, when you hold the car you can feel it vibrating. When you accelerate, the motor will go 100%, but also the wheels will turn right without touching the steering, you can turn the wheels using the throttle. And same when you brake, the wheels will turn left whilst the brakes come on. When you turn right and leave the throttle alone, the servo will start to vibrate (it sort of does very fast pulses between -5 and positive 5) it doesnt go full lock like it should. At the same time the motor will start moving at about 20% thorttle. When you turn left the brakes come on about 20% and the servo once agian just basically sits at neutral vibrating.

To fix the problem I have to turn everything off and unplug the servo and esc and then plug them back in again and it will then work fine. It probably happens about once every 15 times I turn it on. No big deal but its kind wierd, and a pain in the ass. I have tried the cap, doesn't fix it.

Anyone had this problem?

Coons, can you try a couple things for me, one at a time?
Try it with a 6-cell pack

Try a different ESC

Try a different receiver if you have one

Unsolder the motor.

Let me know what happens.


MCGmark, issues are going to crop up with any new technology. What's nice is that there are people here who are willing and able to help.

it did almost the same excact thing with me, using a duratax intellispeed... i would have the radio on and then turn on the car and before it would bind with the radio it would turn its wheels to the left and accelerate about 40 % in reverse. did it every single time. i called teck support and they said bring it in. i get it back all they did was solder the antenna back better looks like, cuz i had the same exact problem... then i tried it in a different car, i put it on a TC4 with a lrp esc and did the same thing. then i tried in another car with a novak brushless system, did the same thing. i called teck again they gave me the voltage protecter, i installed it and darn it it did it again. So i called teck again, and i told them hey. i used the damn recever on 3 different ESC 3 different cars. My other spektrum receiver didnt do this. so they said they would mail me out a new one, which is cool by me ;)

Ok, I should be able to try most of that, but it may take a while for me to report back as it doesn't always happen, so I have to catch it when it's doing it then try those things.

Spektrum Roll Out Factor
 

All: I just bought the telemetry unit for my electric TC4. The RPMs seem to be accurate for the motor I'm using and the spur/pinion gear ratio I've got.

I noticed that the manual suggests that the Roll Out conversion factor is in inches. So, for me, when using both option a and b, I come to 3.17 inches per spur gear rotation.

However, when I enter this into my specktrum as 3.10, I get 327 MPH. After some simple math, I discovered that the actual conversion factor should be in 1/10 (tenths) of an inch... so if I plug in .30 (I can't plug in .31, unfortunately), I get the correct MPH...

Is the manual simply wrong? Or is there a software bug in my telemetry unit?

Anyone else run into this before?

Is anyone making a lipo/lion pack for the DX2/DX3 radios? If so, any modifications required to fit and connect?

hi
 

just a question im using a 1/10 scale car, stock motor and 19t with gtx esc. do i need to buy a cap for my receiver? i'm using 3pk and sr3000 rx i haven't tried it in a race. so far on what i read, there's a failsafe that's going on in the middle of the race and i think it's in the 1/12 scale or something where they are using 4cells only? i'm just curious if i need the cap because i'll be joining a race next week thanks. and i bought it used already.
