I put a M3 8.0 in my 2 wd buggy and now it is slowing down after running 20 feet. Sometimes it can go for awhile, then starts slowing down. I am using a Tekin RS and I may be over loading it.Is it the motor or esc?

the RS will display an error on its LED's .. I think its a battery problem, or a connector problem.... solder connection..

check your batteries...

It looks like the battery was too low to run it, thanks guys. I am still wanting to get an RSX so as not to worry about it.

RSX is on its way, and I will be changing batteries too.

Installed the RSX esc and replaced the battery. Now it really goes!! I am racing it tomorrow (B5M) and will see how it does.
