Default The Definitive M-03/4 Thread

I figured I'd start this thread because of the increasing popularity of this wonderful racing vehicle for everyone to share pictures and tips on how to "TWEEK"and mod your M-03/4S-M-L-
I'll post up my torque rod mod once i perfect it. but if yall havent seen it yet, here.

M-03R
The kit comes loaded with all the parts you need to make it race ready,plus it comes with all the stuff most people wouldn't consider buying right after you just forked out a hundred bucks for the kit, believe me the extra things that come with the R are more than worth the extra money.
I'll list a few of the things that were most important to me:
ANTI-WEAR GREASE!!!!this is hands down the cheapest most effective part that i think the M-03 will benefit from.i found that the gear diff using AW Grease provided more limited-slip action than my Manta ray diff, i still have to try that in the MR diff though.
All molded black parts are chromed black-i heard these'll be worth some $$$$ someday-because of its limited production
Chromed wheels-standard tires "treaded" feel pretty soft i dont think they would last too long though
Short Spring Set: 3 different stiffnesses same color-sneaky sneaky
Limited Clear Blue Super mini CVA shock set(plastic)-comes with clear o-rings i think these provide less friction than the red ones, plus all parts, yes
ALL are clear blue
many aluminum blue ano'd parts:
motor heat sink
front knuckle set
rear uprights tapped in center for floating hinge-pin
servo mounts
4 threaded snap balls
8 spacers__________________________
Genuine Tamiya Metal shielded bearings=smoooooooth
rear adjustable camber link, very useful if you change tires frequently.
rear stiffener with metal sway bar mount(TL-01).
There are surely a few parts i would've liked included with chassis......
Better tires
ball diff
more aluminum
sway bar kit
carbon gear shaft
better pinion
quick release battery door
My take is, get it!!!! you wont be disappointed!!!!!! The car went together like your typical Tamiya run of the mill kit, it was just "cooler" every time something that was supposed to be plastic got substituted with cool Aluminum goodies.i personally tried to get all the parts i could to put in it so i didnt have to take it apart again.i did however change the upright snap balls to the swivel pass through type, because of the opportunity to break aluminum in the event of a high speed collision i've found steel to be far superior in strength by comparison-plus Jesus told me so.. i installed these using a 3mm screw that passes through the knuckle arm and a 3mm nut captures the swivel.
These are the additional parts i used:
TL-01 Qiuck release Battery door
TL-01 sway bar kit
Super low friction Shocks
Futaba S9650 Micro digital servo
Things im waiting for:
Tech Racing Delrin Arms
Tamiya Swing Shaft
Tech Racing Chassis stiffeners
Tech Racing blue King pins
3 racing TI-hinge pins
Tech Racing TI screw set
Tech Racing body mount stiffener
3 Racing turn buckle set

i havent driven mine as of yet but i think it's gonna be a real performer, we'll see.

RC is a sick addiction for me.Anyway guys/girls-POST AWAY.

Nice Idea for the Thread Kila.

So the TL-01 sway bar kit works on the M03/M/L?

My M03M is pretty much stock with the addition of 3Racing TA-05 alloy shocks and Bearings in the gear box.

I am adding a TA-03 ball diff and cvd's eventually. I need to pick up some Anti Wear Grease to try out in the stock gear diff.

I would like to maybe lower the ride height a little? My 3Racing shocks are as low as they can go in the front. So using the short Tamiya springs will bring the ride height down another 2-3mm?

sway bar works!
You gotta be careful with the tc shocks, the m03 uses a smaller body as the upgrade, this allows for more suspension squat, allowing more movement before bottoming out. you'll need thicker oil when doing this though. more dampening.

Kewl thanks for the info!

I had the shocks on hand which is why I used them. The shocks are longer the M03 specific shocks but close. Even going to the short Tamiya springs will still leave me with good suspension squat.

I am running 60wt. currently and I like how it is working.

Have you seen Jeff's Mini? He has it sitting at 3-4mm of ride height with the super mini cva's. I am at 10mm and and there is 12mm of squat.

SWEEEEET Kila

Can't wait to see you run around everyone

Is that servo mount adjustable? It lets you run a standered or micro sized servo?

thanks, it is kind of adj. i had to put both screws in at the same time, then pull the servo in. i ont think it's made to allow for this type of servo. but i do rock crawl too, so my mantra is "make it work, make it work(chicken blood)."it'll fit just about any standard servo properly, but i liked the weight savings from the already high CG so i went for the smaller servo, for a pretty small plastic geared digital servo, its pretty darn fast and strong.

hey, i like how you did the steering with the nut on the links...extra protection!

a small tip from me to all mini racers, dont use the aluminum ball studs on the steering kuckles! use a steel (or ti) screw, ran from the bottom up through the knuckle, put a few spacers over it, and a female 5mm ball. try to make sure the turnbuckles are level. (reducing bump steer) also, turn the steering all the way to the right, if your kuckle is touching the chassis, trim off the top few fins from the chassis using side cutters. this will maximize your akerman and turning radius.

if anybody else has any useful tips they would like to share, please post em on this tread...

i ended up using a longer 3mm to pass through the top swivel, into the knuckle, i seems like it'll work out alright.

WOOOHOOO! That's a brand new MO3R all dirty already. Somebody is practicing hard already. LOL!

What's the minimum speed and torque servo folks are recommending for the MO3Rs?

same here, still in box

I did trim some of the parts and built a few items like the ball diff and shocks but that's about it so far

mines almost done, i think in the process of making it lighter, i made it heavier.but it looks fricken crazy now. today i installed universals, arms, ti screws, front upper links, gears, fan,hinge pins.i think i need to shave the arms a little, too much drag in suspension.no slop at all!!!!!im still waiting on body post brace, and shock tower braces, blue bearings, heavy duty wheel pins.
