I have a problem with my M-05.

The steering doesn't always return back to the neutral position.

What's the cause and is there a way to fix the problem ?

thanks in advance.

If you're using the stock linkage, more times than not that's the problem. Bends very easily and requires only a slight bend in one the arms to really bugger up steering.

Other than that, check your servo saver. Last check your servo. If none of those three, you've really got some work to do. You'll have to check more stuff than I'd want to list.

Servo or servo saver could be broken.

But more than likely the steering linkage.
Try putting a lot of toe out on the front of the car to see if it helps the issue.

Oh also disconnect the rod to the servo and check that your steering moves freely.

don't forget the steering knuckles are easy to get bent too unless you have aluminum upgrade ones installed.

How about the servo?

I have been running the 3Racing ball diff in my M03 and my M05 after the TA03 diff broke ,

The best thing to do it used the TRF screw , nut and thrust bearing , lots and lots of ball diff grease and some ceramic balls then build it as tight or loose as you want then your off .

The good thing about the 3Racing diff over the TA03 diff is it is easy to adjust 1 screw , 1 ball joint off and a 1.5mm allen screw and it is tighter or looser , just like a Touring car

i run my M05 EVERY weekend indoor and outdoor and the dif is still like new , no wear and no damage on the diff rings and i did wind if F%*#íng tight one weekend for a race.

i will do a build video soon as i need a rebuild on the diff

Personally i have never had to adjust a ball diff in a mini.
For me its pretty much do it up as tight as possible, make sure the diff nut or screw is loctited in and drive.

Sorry, mini racing is still new to me but would you have the part number for TRF screw, nut and thrust bearing, also for spare 3-racing drive blades which go on drive shafts.

Diff screw :- 51431
Diff nut :-51341
Thrust bearing :- 9949000
I dont use the blades , my diff its the one with steel outdrives

you can use the TRF blades though Part number is :-53890

Hope this helps you out

Check the tightness of the king pin. Release the steering from the servo and see if it turns smoothly. If it does then your problem is more likely to be servo related. I had a similar problem after putting in the flourine coated king pins. Sometimes it would steer fine and sometimes it would get stuck. I loosened them a little now it's fine.

just to get confirmation, is this the correct Robinson pinion for Minis?

pinion gear
 

this is what i use part number 53509 hard fluorine 06 alum pinion gear

ok...I need a good carpet setup for my m05...it is just the kit version....not the pro....

I have the following to work with

c.v.a oil mini shocks
onroad spring set (TAM53440)
4 "m" grips
2 "s" grips
4 kawada racing tires
4 hpi supersport tires
4 hpi x pattern tires

I need to run it in the short wheelbase.

what are the most important things you mini Gods look at on the cars?

Thanks to everyone for their help. It appears that the rod / linkage to the servo was bent.

Is there an alloy version available for the M-05 ?

cheers.

Hi guys.

Running my upgraded m-05 in our informal club here and loving it.
We recently concluded a Race Series and was it a blast!

Reading along this thread is very informative. Thanks for the infos shared. :D

Keep it up!
