Default Hello - Tamiya M Chassis M03 Mini From Chile

Hello, I´m new here. Very good forum.

I participate in a category of Tamiya M03 Mini! (90% of the group have a real mini).

The basics rules are: Motor 27T, 24º, 22 AWG, ball bearnings, 60D Wheels, any tire, M03 spur gear, ESC Free, Austin Mini Body.

But for the next year, we have the idea to include chassis m01, m02 and m04 with any type of body.

My question are:

- what advantage has m04, m02 or m01 on M03?



Here some photos,

Regards,

Andrés from Chile.

I always remember my M01 having the advantage gearing wise. I could get a more gear than an MO3 or M04 so I had a slight topend advantage...but that was with silver 540 motors...regular stock racing motors take away that tiny difference. I think the M03 Swift 1600 would be the way to go. Minor updates over the Cooper, but worth it.

The M01 and M02 have a lower center of gravity and apparantly work really well on carpet tracks. The M04 is just it's own little monster, but it did win the TCS Nationals in Cali. so I guess the answer would be how much time do you have to really get your car to perform the way you want?

Yes, the internal ratio is slightly lower, but I couldn't tell you the difference.

M03 and M04 transmission gears are identical but the case is different. M03 takes a max 20 tooth pinion, M04 takes a 21. And there's your sign.

Found something interesting about the gear ratio, take a look:

Tamiya M01 == 2.4375
Tamiya M02L == 2.4375
Tamiya M02M == 2.4375
Tamiya M03 == 3.134
Tamiya M04L == 3.134
Tamiya M04M == 3.134

Now we know where there is a big difference.

From memory I think the final drive ratio on the M01/02 is 5.65:1
Where as on the M03 it's 5.8:1

Schottky diode will increase breaking peformance and also lessen the chance of damage to the ESC from reverse current.

At least thats what I've been led to believe
