Double check your motor connections.Ive had cogging when I first installed connectors on my 1512/1.5D the wires coming out of the motor were huge and 1 of my connectors wasnt soldered correctly.I resoldered the loose connector and all ran smooth.

All connections are good. The buggy goes great for the first 10 sec.,but, as i turn around and accelerate, it coggs like crazy. Let off the throttle for 2 sec and then it seems ok until I turn and accelerate hard again.

your batteries? or the esc? i have a feeling that they justa cant supply the current required, and once u have used the burst rating (10 secs) then it struggles for the power.... try another pack from somene else if you can and see if that helps :)

hope you get it sorted.

Well, I just put my 9xl back in and ran it for 15 min. and the esc ran perfectly...go figure...I guess the esc has an attitude problem w/the Neu!

What you are describing sounds like a current issue, not a cogging issue. True cogging only occurs right at start up when the esc has trouble finding the rotor position. What batteries are you using?

Even w/my 9xl there is a SLIGHT hesitation at start up.

You have your timing set to the lowest position? Neu motors, at least the 1515's are suppose to be set to a low timing setting.

It is set to a low setting, I don't recall the value off the top off my head, but I will check later today. MY timing is set for 5 so maybe I will try to bump it up to between 8 and 10 and see what happens.
