Why does my mini-z swerve a very little bit even though i\'m not moving the wheel? Is it just from a slight interference getting to it and making it twitch? Or is it cause it\'s kinda sloppey up there and wheels can move a little cause they aren\'t held on that hard? Would a front stabilizer bar that they sell fix this?
A stab bar wont fix the slop it will just give toe in or out or do nothing... if you hold the car in your hand and give it throttle slowly and as you give it throttle the front wheels start flailing back and forth like its mad... then the motor is causing too much interferance.. you need to re-shield themotor.. with a 3rd cap or new caps etc..
but it\'s not the throttle, just the front wheels, they twitch i think, gas works fine

that is your servo glitching.
mine does it too... i even messed with the potentiometer on the front left-hand corner of the esc... still no luck. i will let you know if new crystals are the key!
I saw some people putting Capacitors on the motor to stabilize the flow of energy to the motor and I read somewhere that it stops the interference... is that correct?
some have gotten away with spraying the pod inside the servo with electrical cleaner (wich some brands eat plastic keep away from teh chassis parts)
(wich some brands eat plastic keep away from teh chassis parts)
.... whaa???
I had the same problem and someone suggested I insert a piece of paper between the servo case and the potentiometer (the little circular bit at the fron of the servo). I shimmed the paper in there and presto!!! problem solved.
Oh ... and to clean the electronics some people use brake cleaner (use the weaker kind though as the industrial strength will cause the plastic parts to swell :o )
okay, the paper thing worked for me!
WOOOOOOHOOOOOOOOOOOOO!
SÒ? when my car goes straight in full gas after 2-2.5 m it suddenly goes to left . why is this? is it dangerous? would it cost me money HELP!!!
did the front wheel turn aside itself?
if yes, check servo power source & VR unit.
if not, remove all bearings & clean it.
Also, don\'t tighten too much your front wheel locknut.
Help me please!!! Should i try to scrap off old solder on the Connecter to the Antenna and resolder or what? coz ive solder 2 and the soldering is Quite too big... What should i DO!!!
And by the way. i crashed alot like more then 10 times a day
Did you try the paper thing in the servo?
Also... does the problem happen when accelerating slowly up to top speed or only when giving it hard gas? If it only happens when accelerating hard it could be your ball diff adjustment.
-kai
Its full gas ... But ive tried unlocked the ball diff alot of time ... but it seems if i full gas ... i kinda can see the front wheel swerv to the side...
heyyyy the paper thing worked hell yea!! i just ordered new motor, turbo, diff, bearings, rims/tires so i can\'t wait to see what it will do when they come.
even in a real car, if you punch it, your car may not go straight forward if you have lost all rear traction..
I think that the problem is that the tires arent on perfectly straight, so when going straight, they cause the car to swere very lightly...
Just my opinion;)
Stoopid question. Anyone have pics of the \"paper trick\"????
yes check my site
Anyone know why the paper trick works?
i explained it on my site....
anyway, it cuz the plastic servo casing for the steering pot is sometimes loose -- therefore giving the pot some play and that\'s why it keeps adjusting itself because it doens\'t even have a firm sense of its surroundings.
thnxs baseline!
Just a thought...The diff,in the mini z is not in the centre, the left side shaft has 2 bearings. The right side has 1. Maybe its because of the extra friction, making the right wheel spin faster, and making the car go left??
Yeah I notice this alot when i stamp on the accelerator. It kinda spins the wheels and goes to the left a bit.
also i find that on carpet i drift to the left. I think this is because my diff gear is grabbing the carpet and leading to slightly more grip on the left side.
I mean right side.

drifts or vears? if it drifts, even though your car is tuned well on solid surfaces, it might be the diff.

Thank You for the explaination AND for your kick-ass site! Those pictures are a tremendous help. It may be that my ignorance is because I am still so new to the hobby, but I just couldn\'t picture where that paper went. On another site\'s forum they discussed it but the only help given was to \"do a search for it and you will find it\". Well guess what, a search didn\'t turn the info. I gave up until I saw your pictures. Thanks again. :D

I checked the site out and i did the paper shim thing. If the ball diff is the problem in causing the car to not drive straigth what can you do to the diff? Right now i have it lock pretty solid. Should i make the ball diff a little looser?
Thanks

if you want to check to see if it really is your ball diff, put in your stock diff and see if the problem persists. i would recommend that before you spend hours tuning your diff :)
not sure if my stock diff is going to work since i\'m using the GPM motor mount. I could be wrong though. I\'ll give it a try But if i happens that it\'s the ball diff what should i do? Is there anything i can do to fix it?
Noobracer
I tried it with the stock diff, it still does the same thing, not as bad, but it still curves to one side
Noobracer
if your having a problem with the rear of the car spinning out when accelerating, loosen your diff until it will actually slip while you are holding both tires and accelerating with the radio at the same time, youll notice a tremendous difference in you ability to accelerate straight!!
I'm having the same problem everyone is talking about. When I go full throttle it totally spins out.
What should I do? I just have everything stock...
the problem with the servo can also be fixed by putting a better potentiometer in the servo. they are available at www.hobbyetc.com last time i checked. there is soldering involved,but it permanantly solves the problem. they also have delrin servo gears that are way smoother.
