How long can you run, race speed, with this 4000mAh pack? Do you see any drop off in performance?

Do you think the pack will last a 30 mins final?

Thanks.

30 minutes main? For real? Even on stock brushless...I think it can run for 10 hard racing with a 4800/5000 mah...30 mins are way too long (I think).

Just kidding on the 30 mins final......

Just wondering really how long a 4000mAh battery would last.

I remember an old 3000mAh battery pack (NiMH) would last 5 mins no problem.

Do you think the pack would last 15 mins? Do you guys run any sort of regulator on the Li-Po packs?

Did not try the pack at the track yet. Still waiting for the friggin snow to melt and season to begin in may here in Montreal, Canada !

My guess on a 10.5 BL motor would me 12 minutes max with the 4000 mah SMC pack.

I tried the set up this weekend and it worked pretty well,The changes to the rear of the car were very good,But the frontend changes mad the car way lazy.so i made some a couple of of small adjustments from the (Luis) setup and got the car faster with a spool then a 1 way.Thank you Luis for the setup.I will post a new setup sheet in a couple of days of the changes.Thanks Doug Lemmons

for carpet or outdoor?

Yeah, kinda thought you are joking about that 30 minutes main...but if there are such LIPO can do that...I think I can quit NITRO for good.

Anyhow, I used CORE 5000...Speed Passion speedo with Novak 13.5 on Schumacher Mi3...ran back to back two 5 minutes qualifier (forgot to charge the other lipo-4800 so I have to take my chance) and I am sure in between those run I have like 2 or so minutes of practice...completed both round without any power drop. I did not charge the pack after to check the mah left but I've charged the pack immediately for the 3rd round and the main.

Anyhow, 12 minutes is a garantee for brushless 13.5 with juice left. Probably 10 minutes for 10.5 and 7 or so for 3.5 4.5 motors...

I don't use any cutoff thing or regulator.....is there a voltage regulator for EP use..? I thought regulator is the voltage reduce devise designed for receiver packs GP cars use.

Use the Smart-stop module from Novak:

"Now users of all models and brands of ESCs can appreciate and enjoy the advantages of Lithium Polymer (Li-Po) battery packs without the fear of damaging the cells. The Smart-Stop Li-Po Cut-Off Module will monitor your Li-Po battery pack voltage and prevent the batteries from going below the critical safety voltage level. This is achieved using a combination of throttle interruption and a visual cue from the included ultra-bright blue LED. The Smart-Stop Modules are available for 2-cell (#5470), 3-cell (#5472), or 4-cell (#5471) Li-Po battery packs and can be used with any brand brushed or brushless speed control for car, boat, or air applications.

For racers and bashers alike, the Smart-Stop Module will prevent your vehicle from draining your Li-Po packs below their safety level. The Smart-Stop Module connects between the receiver and speed control, and is easily set up with a One-Touch Set-Up button to learn the ESC’s settings for accurate and complete control. The Smart-Stop Module will interrupt the ESC’s throttle operation with short periods of throttle blipping. This is a warning that the Li-Po battery voltage safety level is approaching, giving the user a chance to bring in the vehicle. In addition, the remotely-mounted, ultra-bright blue LED will begin to flash, giving a clear visual cue that it is time to stop the vehicle. If the vehicle is run beyond this warning period, the Smart-Stop Module will bring the motor to neutral while leaving full steering servo control."

Thanks...I know about that Novak thing, I have 2, NIB, never use it, cause never need it....but I thought "REGULATOR" is different then the "CUTTOFF" device. Anyhow, nevermind....

The regulator will only handle 3 amps and this is good enough for a receiver and servo but no where good for running a motor .

Thanks for all the input and replies people. Your a good set of guys on here and a credit to the r/c world....may I say.

Between you all, I think your taking the E4 to the next level and developing the car.

Good to see.

Regards to all.

This last Sunday, I had finally seen the E4 in person. It really is kick ass. If I did not have the TC5 already, and if the TC5 wasn't so easy to bring to legal weight limit with Lipo and weights from PPDbillet.com, I would get one.

The biggest problem I see is setup help locally. I really wish TM the best in breaking into this tough US market.

It was a Virgin National 1/10 EP Race to me.

My E4 got 4th Positon in total 5 Qualify races.


In 3 times A-main Race.. My E4 did not go well.

i reused Battery in A-main that used in Qualify.

My E4 was too slow in top speed.


i finished 9th position in A-main.

But it is very good experience to me.

I am wondering...what is stopping racer over ASIA to not allowing LIPO? Not in Hong Kong, not in Japan and not in almost everywhere over EAST.
My Nimh batteries now is for 12th scale, Trans-Am, Nitro car starter box power supply (use IB4200 WC cause they are JUNK) or some heavy paper weight..........

what your car was slow?
