please help...bad cogging

[ncnguyen123]

thanks all! i think you are right about the batteries. I recharged the batts and ran the truck with batts hot off the press. cogging almost went away. however, things got progressively worse as batts drained. looks like i may need lipo, but a little too much $$ for me to spend now. i'll try and gear down to see if it helps.

this forum is awesome!

i'm using a futaba FM radio.
