I would strongly recomned getting an IR temperature gun Mentat, its very important to know the temps on your batts, esc and motor. The 3 second trick of touching the motor works, but thats not a good indicator of actual temps; one persons hot is another persons boiling and all that...
180*F max for the motor, ideally 120-160*F.
120*F max for lipos, ideally 100-110*F.
160*F max for the esc, ideally 100-140*F.
