Tekin can clarify, but it seems like the RS only want to see 6v. I have a regulator, but opted not to use it just to save weight. I'm going to put it in now, but I still need to get another.

And now that I think about it, there have been a few people who have mysteriously failing RS's. I can think of at least two in the past weekend. I can't say for sure, but most people are running 2s rx packs. I have been running a booster all carpet season and only ran a RX pack strait to the RS for the first time this last weekend. I guess I got lucky.

I am planning on trying a 1S Lipo system on Wednesday. My intent was to tape the ESC Power Switch in the OFF position and plug a 6 volt 5 cell receiver pack right into the receiver BATT plug.

Will this work OK, or should I be doing something more?

Thanks!
If you take the red wire out of the speedo receiver wire you are preventing any electricity from the receiver pack from reaching it.

So is it that simple? Can we just take the red wire out of the ESC lead? I really don't want to add anymore weight. If this works, I'll just make a servo wire extension with no red lead.

I am currently running the SMC 2s lipo made for 12th scale, with a regulator on my RS PRO. I am having no worries at all with it. working great Just run a regulator and you will be fine. Just remember to charge the battery

I have been using the Trinity/Epic Mini LiFE 6.6V 220mah Receiver Pack with the RS ESC in my WGT for 3 months now. No issues; except, I had to replace the Mickey Mouse on/off switch on it.

Leaves me with max power from 1S to the motor.
The running voltage of a 5-cell NiMh receiver pack will be about 6.5v (1.3v per cell) so I too assume Jim means LiPo, not LiFe. It's the voltage that's the problem, not the number of cells. Had no problems with my 5-cell NiMh pack...

A quality regulator is going to add like 1 ounce tops & lipos will shave that weight right off. If you only need to run a 10 minute race then drop like a 500mah lipo w/ a regulator & go race. I think what we should see is a 1s w/ a 500mah 2slipo w/ regulator built into the hard case.

Where are these (Mini LiFE 6.6V 220mah Receiver Pack) in stock? Can't find them anywhere. I don't want to risk running the RS without it.

We do not really care if it is a booster, regulator or a battery of any type as long as there is not more than 7v.

LiFe is 7.2 fully charged, but drops below 7v quickly with any load and should be fine.

We are on the edge with the 2s lipo it appears because many have worked for some time, but too many are failing. Nobody likes to not finish on a race day regardless of the reason.

Well my charger is not designed to charge LiFE so it looks like when I get my 1/12th running again it'll be a LiPo RX pack with a regulator.

Is removing the red wire from the ESC lead a suitable work around?

No need to use an external booster nor external regulator. Use the ESC's built-in regulator. This setup is the same as using a single 7.4v battery race pack to power everything. Many 12th scale racers have done this mod and have worked flawlessly for many many months. I have been using this mod for over 2 months now and no issues. Modify at your own risk and may/will probably void your Tekin warranty.

I like that idea If Tekin is ok with it. When doing it like that, is the ESC able to use the 3v cutoff for the lipo, or is it detecting the 7.4 coming from the reciever pack?

Dunno & that's a good question, I never ran my 12th scale batt for more than 12 minutes so I never got down to that level of voltage.

I would also like to know Tekin's opinion on this and how is the circuitry working. All I know is that it works and all the fast guys have been doing it for many many months and have no known issues so far.
