In comparing it to M05/M06 it benefits from:

1. improved plastic

3. ease of changing wheel base
4. lower LCG than M05 but not M06
5. Sharing of parts with TT series eg low friction suspension ball, differentials and spools
6. droop adjustment

The bad:
1. it shares the slop of the M05/M06 as well
2. Limited gearing: which keeps competitive with M05/06 but not the 07/08
3. Body mount: some bodies canít be lowered to desired lowest point.. this is why the Abarth look high up in front
4. ESC: the HW ESC had permanent drag brake, which makes a very slow car stop instantly 😂
I'm not convinced the CoG is higher in the M05. The battery, motor, servo and ESC all sit lower in the M05.

True, but bulk of the chassis has greater height front to back.

One of my locals did a test run with his MB-01 and found it had no steering. I've just had a look over mine and the steering angle is pretty small.

M05 steering limiter at 24 degrees


M07 steering limiter at 28 degrees


MB-01 steering limiter at 14 degrees


I might end up trying to swap the arms left/right to move the steering limiter to the bottom of the arm, that might give a bit more steering.

I heard this from someone on TamiyaClub. I didnít feel that it lacked steering when I tested it..

The steering is fine when you run it. My m07 steering is reduced dramatically to work well on indoor carpet.

Except on our track it wasn't fine. Too much understeer.

M05 is actually shorter than the MB-01 as well.

With FWD set up I had plenty steering on asphalt. I switched to RWD but have yet to test. If pushes, you can adjust for it with set.. eg softer front spring oil, standing shocks up, more open diff for rotation, adjust steering toe out and toe in in back, saucing front tyres more or even fully.

I ran it yesterday rear wheel drive with S grip all around. It had plenty of steering and the shimming I did to steering made it precise. It drove fine but with limited gearing makes it very dull.

The M05 / M06 you have the 3 racing gears that will make them competitive with M07/08. The MB01 at the moment doesn't have any options unless you start to cut and grind things. So it wonít serve my purpose for racing and will be placing it for sale later this week.

Built it with all hex and full bearings. Pm me If anyone is interested in the chassis,

Iíve been waiting to see what livery they came up with.

1. They added an auto delta triangle in front of the four leaf clover
2. added number 53
3. Italian flag on rocker? Or is that paint?
4. X on head light.

No serpent and cross? overall, very lazy decal sheet! The number should have been 33, which is Alfas lucky number, not 53

I actually bought the Citroen 2CV body which I'll run sometime in the future. (its the lightweight version so its the next best thing after the MX5)

Nice idea. This chassis really feels slow. The top end even with that 29t pinion makes you drowsy lol. It needs a high speed gear set
