drive frequency smooths out the feel. lower = more punchy higher = smoother. increasing the drive freq increases esc temp and can increase motor temps also.

That's way too hot for the motor! I keep mine below 160F, and most manufacturers say to never exceed 175F.

i like the 120 on the lipo, lol. good way to start a fire

120 on a lipo i would be walking away fast. i never run over 10 mins at a time finger goes numb anyway.

On my novak you can tell the difference between 100 to 150 epa,i run stock so ya you can tell the difference. same thing with epa on brakes, huge difference between the two.:cry:

lol, you cant go faster than 100% on the esc. Some people claim its smoother because there are more step from 0 to 100%. I am very sure if it made you faster, roar would be all over, but it doesnt. if it did, I would set my epa at 1%, then calibrate and then set it to 150 so I could zoom like a rocket :)


When I have seen people go past 100% after calibration, the normal issue is sputtering at full throttle. I have seen this with spectrum and airtronics controllers, with a few different brands of esc's


Edit: I just tried this with my viper. all that happened was, I hit max throttle at 75% trigger pull...

But what if I cut a hole in the floorboard or my car?

Thanks Nick. The Ambient temp at the indoor track is around 65 degrees. I got to run my 22-4 tonight and was able to push it harder with some good setup changes. After ten minutes of a hard run I could smell it but the temps weren't bad - 145 degrees on the motor and 120 on the esc. Lipo saddles were around 80 degrees. All good in the hood!

WildCat - thanks for the input on drive frequencies. Makes sense.

Anybody running this motor in 4wd SCT with success?

Trackstar 540 size 4 Pole 4250KV Sensored Motor

Just wondering if anybody has tried the new trackstar gen 2 120amp speedo yet??? If so what are your thoughts.

Plan to run the 120a esc in my Losi 22SCT (2wd), any issues? With 8.5t motor!

The 120a turbo is what I run in my scx-60cf with an 8.5 with no issues. Super smooth and never gets hot. Should work great in the 22sct.

My son and I run both. The 120 turbo in our SC trucks and the Gen. 2 in our buggies. Both run really smooth, the Gen II is way more tunable, more like a higher end ESC. Just a heads up, the USB adapter isn't available, I even had hobbyking try and find for me while I was on the live chat, also, the turbo and Gen II use two different programmers. One thing I have noticed with the Gen II is that it seems to run a little warm on the buggies. We don't run the fan, we run 7.5s and just a little timing, like 10* and no "boost". It's hit 160 on an. 8 minute run. I reemed a square of a bunch of holes right above the ESC and the temp dropped to around 139. I may need to run the fan but it seems like the hot air gets trapped in the buggy body unlike the SC where air flows all the time. Oh and one other minor thing with Gen II, the power switch is built in so tight installs will make it difficult to turn on and off, ie a TLR 22 in MM.

I recently got the Turnigy Trackstar 150A GenII 1/8th Scale Sensored Brushless Car ESC for my 1/8 scale buggy. It had been working amazingly till a couple of weeks ago. While running the car car shuts down completely for no reason. Everything is connected correctly, all the wires are connected without any breaks. I've had it happen 2 times and can't figure out why. Anyone else have an experience like this?

Going to give the 120a a try on my SCT!!!
