MMP woes

[atf300]

i bought an used MMP with a tekin 13.5 for my wraith , im experiencing heavy cogging in sensored mode , so i think its either the sensor cable, motor sensor board or the sensor port on the MMP itself.

is there anyway to know if the esc connects in sensored mode, i know my hobbyking esc changes lights if its running in sensored/sensorless mode.

ill get a brand new cable tomorrow and then start a process of elimination to find out what is wrong .

any help is appreciated

i found a second cable in the spares bin and got to eliminate the culprit.

its the mamba max pro itself, it just does not work in sensored mode , the port itself is ok , as i've measure the pins with a multimeter and they all work .

there is probably nothing much i can do that send it in to castle or run in brushed mode (or sensorless , but it was intended for a crawler so that is not an option)

hi atf300 ,

i have had endless issues with every castle esc i have owned , they promise so much but cant deliver IMO , add to that the clever guy that did all the firmware for them has left the company and i wonder how long they will be around ,

with your mmp , try cleaning all the pins on the port with a soft paintbrush and some electrical cleaner , it could be as simple as a dirty connection .

good luck

i've measured the sensor port pin with a multi meter and the pins are fine . ill try the clean method before i send it of to castle.

the thing that bothers me that i've bought it used on ebay and the guy doesn't want to give me a partial refund because the esc isnt working properly , and he threw away the invoice, so he can't warranty return it .

i do accept that castles can fail , they are cheaper than Tekin ESCs but still they are not cheap.

very true , any esc can fail , and my experience should not be taken as an example of all castle esc's , even though ive had issues Dan at castle was always very helpful and got me sorted out, its just the whole inconvenience of it that bugs me , my cheap systems are all flawless whn used at the limit of their specs yet the more expensive systems give me problems when used way below the specs ,

as for the guy you got the esc from , if you used paypal you could start a dispute for partial refund as castle are gonna charge you around $60 for the repair add to that the postage to the U.S ,

best of luck.

im still appealing to the guy to just partial refund me without me actually starting a dispute, because from the emails he seems like a nice guy.

this mmp is meant for my crawler so it will not be used hard. so ill use it in brushed mode for a while before i send it in . or maybe just keep it like that and buy another one for the brushless motor .
