This hobbywing esc rating...
 

I dont understand the difference between on-road / off road motor rating.

my esc Xerun 60a-sd says...

With 2 Lipo or 4-6 NiMH
1/10 on-road: >=5.5T
1/10 off-road: >=8.5T

so why difference?:confused:

So esc doesnt know the surface its racing on, is there any reason?

I am planning to buy 7.5T motor for my buggy...

torque -

bigger wheels = more torque needed to rotate at the same speed.

im sure some one will correct me if i am wrong!

Off Road has more drag, basically

hi all,
yip both right, although i use a trinity epic duo2 7.5 with my HW 60amp esc and it only gets luke warm , been running it for 3 years in filthy wet outdoor conditions ,it been soaked many times and so far its been the most reliable esc i have ever owned .
