Does anything know what the top speed record is with a 2s battery?
I believe the world 2s record is high 120s by the Aussie's Serpent 1/10 tc. You got a long way to go....

What speed are normal 1/10 scale touring car rubber tires good for? I just a tired blow on me at 77.5mph. Also how much timing, boost and turbo can I run on my 2s lipo tc4? What else can I do to get some more speed out of my car? So far I’m at 77.5mph in my tc4. I’m running a hobby wing 3.5 turn motor that’s rated at 9500kv. I’m running a skyrc toro ts160a esc. I run a 30t pinion and a 66t spur gear but I did just order a 49t spur and a 40t pinion. I also am running 30degrees of timing on the motor with boost set to 25 and turbo set to 30. This is on a smc extreme 150c 2s shorty battery.

Hello all,

I am new to 1/8 GT speed run cars. I got inspired by people like Phillip Jolley, Michael Baars, Henry Fords RC, Kill Mode RC, Martin Reber and many more. I have done a lot of reading and watching Youtube, but now i have come to a point that i need help from the pro's ;-)
Hopefully one of you can point me in the right direction. I am looking for a spur gear solution, Xray spur gear that fit my car does go any further then 45 tooth. After a couple of posts i can show some pictures.

Thanks

For now posting pictures is not possible, perhaps you can have a look at Xray 345549.

Thanks

So far i got my tc4 up to 77mph on 2s lipo with a 66t spur with a 30t pinion with a 3.5turn 9500kv hobbywing 2 pole motor and a skyrc 160a esc. But i just installed a 55t spur gear and 40t pinion and on the first run it smoked and killed the esc. I then jsut installed a momba monster x 1/8 scal esc on and after one run the esc goes into over heat protection. What gives?? this is only on 2s but this esc is supose to suport up to 6s.

so it it better for the esc in order to not over heat I should go with a lowered if motor but go to a 3cell Lipo?

what motor should I go with for my momba monster x esc?

That's what I was thinking in my head, but it looks like crayneogeo says that is not possible.

On the subject of two ESCs and two motors, is there a specific way two ESCs with two motors have to be wired so they can turn one gear at the same rate other than reversing the direction of one of the motors? My assumption is a dual ESC and motor setup reduces the load each of the motors and ESCs have on them by 1/2.
No one has any suggestions?!

I just want to know what exact motors do people run when they hit 120+mph on 3s or 4s on a 1/10scale touring car. Why can’t anyone answer this question. Please.

I have used a neu 6700 (1409) on 3s and 4s and went 137 on 4s. the reason people don't answer is because they spent alot of time and money figuring out what works.
