Thanks Gary, I posted onto the keyence thread, and ordered the voltage protector as a precaution. Guys were running power caps on G12cIII's? I still have my old one, I wonder if it still works (and if Tekin would fix it if it wasn't)....Hmmmm....

I'd still rather not have one...I can do much better driving a car with less punch and setting up the corners better then I can with more punch...even so I never could tell the difference. I could tell a difference with ESC fequencies and I always preferred the ESCs with the higher frequency even though it was less punch. I'm a bit more used to driving under conditions where traction is less then ideal so punch in our case usually just gets you into trouble faster. Often I find myself carrying much more speed into a corner then my counterparts and able to carry it fine...but it throws off the pace when they aren't expecting it. I think often they rely too much on punch to get them out of a corner and less on taking the right line which is much more important in pan car racing.

RcBuddha - For 5 or 6 cell Sedan racing there is no need for a cap on the motor or receiver when running a Keyence speedo and Spektrum.

If you run 1/12th (4 cell) stock you dont need a cap but if you are a fast 19T driver you will need a cap to keep the Spektrum receiver from fail safeing due to too low a voltage late in a run.

If you run 1/12th Mod I would run a receiver pack as you are pretty much always near dumping late in a run and the receiver cap can only do so much.

These are pretty much the same rules for any speedo and normal FM receivers. The Spektrum Pro system is only slighty more sensitve to low voltage than FM receivers

Thanks Adrian, I knew you'd have the Keyence question covered

I agree, thank you adrian!

Just want to verify this...I didn't think the recievers had a voltage regulator and just passed on the voltage that is input. This from the Spektrum FAQ makes me nervous:

"What is the voltage range of the SR3000 receiver and can I use a 2-cell Li-Po pack direct?
The receiver can handle up to 9.6 volts. The real limitations are the servos. Some servos are capable of operating at higher voltages while others are not. Check with the servo manufacturer that you're using for specific details."

If the reciever regulates the voltage then the servos shouldn't be an issue.

Does anyone have a pic of how the antenna wire in the module is supposed to be routed? I'm beginning to suspect this is where I'm having glitching issues. Running the reciever off the 4cell main battery pack did not solve the problem.

Also I noticed there are 2 spots on the pc board where the antenna can plug into...what's the deal with the 2nd spot?

Just spoke to one of our engineers and I was wrong about the voltage regulator. Now I did discuss your situation with him and a few things that he mentioned:

If I understand how you were wiring things with the 4-cell pack and all, you were connecting your main battery pack to both the main power leads and to the battery input of your receiver, is this correct? If so, you are risking possible damage to the transistor on your ESC. You can't back-feed voltage into the Receiver like this without removing the red wire from your ESC plug harness.

I know we have a photo of how the antenna lead should be routed in the module. I have a meeting to run to in a minute but I'll try to post something in a bit. Just to tell you what it look like, the lead should go around the outside of the PCB, not over it.

Question, is this a Pro Series Module or an Original Series Module?

Tres, you da man!

Did you get tthe e-mail I sent you Friday about the bearing?

Yes, pm me a #, I need to talk with you about it.

wait, there are bearings in the Spektrum Receivers now?

Shhhhhhhhhhhhhh, Uber secret man, but it's worth 2 laps, guaranteed! Just gotta make sure that you use sheilded bearings to prevent interference. Sheilded? Get it? I'm so clever sometimes

Actually, Tres was lost, so I am trying to tell him where to go so he gets his bearing again! Oh, I'm on a roll.

Thanks for the pic! My antenna was definately wired wrong then as it was faced the other way and wrapped around the top of the board. Hopefully this takes care of the issue.

As for powering the RX this way...From what I've been reading in the 1/12th forum most current ESCs are made to detect an input voltage through the servo harness and automatically turn on. So you only turn on the power from the reciever pack. If you turn both on you risk frying something. If you remove the power wire from the harness you have to turn on both the RX pack and the ESC. To ensure this I removed the switch from the ESC. The ESC and reciever seems to have ran just fine this way except for the glitching which I am fairly convinced is an issue with the module now. If this antenna re-route fixes the problem I'll be able to run everything normally.

It's an original series module. I have a couple of regular series recievers and a mini pro reciever. Currently I'm running the mini pro reciever in my 1/12th scale.

Let me know how it works. I again would still strongly reccomend using a power cap on the ESC, but we've been through that
