cogging noise on the mamba max 9xl setup

Hey guys been running my setup and its been running smoothly except today ive been hearing these cogging kinda of noise. i really dont know where its coming from. my friend told it could be the sound of my dogbones hitting the cupand told me to put some kind of foam to stop the noise. what do u guys think? oh by the way tried my setup on 2x 2s 4000mah 7.4v lipo and its wicked compared to my 2x 6cell 3300mah 7.2v nimh. what a big diff it makes. Also having some problem tried speed testing it front of my hse and it would go on brakes for half a second without me braking. do u think its some kinda of interferance? do u think its the ubec?

Is it just a noise or does the truck stutter?

[crazyjr]

Are you running a failsafe? the braking thing may be the failsafe kicking in

I think its more of a noise than a stutter. but as i said it would brake by itself! What's the failsafe? I already installed the ubec. It wouldnt even heat up as much. By stuttering you mean it wouldnt start right away on start up?

by the way i ordered some stuff from mike and it said on the order tracking that payment has been recieved. When do you think they will ship? I ordered it on dec. 5th. do u knw how else i could get in touch with them?

Does this happen when starting the motor (when cogging usually occurs)?

im running an emaxx too! im using a jr racing am controller. and a futaba rx cause the batt output in the jr isnt working so that i could use a fan

no it happens during a turn and i i accelerate

I've tried talking with castle about this through email but we were really not getting anywhere.. could this be interferance ? we are both running AM radio mines the stock tQ3.. thinking of selling this esc and getting the bk9920 myself..lol by any chance were you running near power lines?
phil

its more like a clanking metal sound

yup i was ! tom ill find out if there is anymore problems. I think its more of our controllers thats the problem

well if you are that would be sad ! man and i was just starting to like my setup! now would be the right time to get the bk from mike its on sale for $150
