Hi,

my awd mini-z seems to be very glitchy whenever I have a fully charged battery installed. By glitchy I mean the steering will move left & right frantically even when I'm only inputting throttle (and its off the ground).

It gradually goes away once the battery drains a bit, but it'll always glitch if I put full throttle, which is even more dangerous since the throttle would often get stuck/glitch for a good 2-3 seconds where it goes full speed and I can't do anything so it'll eventually hit something (made a few scratch on the gtr body :( )

Can this be fixed if I stack some fets? or am I better off getting new rx unit?
I have a mr-02 and I can say this doesn't happen with the mr-02...

Have you tried a different motor?

maybe a new set of brushes for the motor might help??

try opening it up and check if there are any pinched wires (check the servo gear and servo motor wires) under the chassis. hope this helps. :D

if it is a recent development for a car you've had for a while I'd go with suggestion 1 or 2....my ASF cars get super glitchy when the motor brushes are worn through

Wow thanks for all the quick replies!
I believe its been like that since I bought it in japan 3 months ago.
I've reassembled it to check the cabling.. seemed fine.
Didn't think of changing the motor, ill try that next.
I do see sparks coming from inside the motor but isnt that normal for a brushed motor?

You get sparking even if one contact is worn through.
