DEX210 RTR MM conversion ?

[slippy]

Hi all. Has anyone out there done the MM conversion with the rtr and does the parts bag that came with it have all the parts to do 3 gear mm or do i need other bits like screws ect.

You will need,

1 x extra idler gear
1 x idler gear shaft
2 x idler gear bearings

Screws to suit - see the online manuals but I know you can pick up a full screw kit for about £10 which is always handy to have around anyway

Cheers mate that's great now I know what i need.

Luniemeister has given you some of the parts list for mm4.
I think you need 2 idlers, 3 gear uses the large idler, 4 uses 2 small ones.

But tbh. That's the best one to go for anyway!
I also converted my diff to a 4 gear one. Just needa cross shaft, a couple of gears and the spacers.

Hi. I have looked into this further and all i need to do for 3 gear MM is take out the spur gear shaft and turn it round as the car comes 3 gear RM and all the plastic parts come with it all but two screws. Can someone explain the benefit of 4 gear when the added gear is the same size and does not seem to gear it up or down but just reverse the motors action if you want the motor on that side of the car also this puts slightly more load on the motor for seemingly no gain. I,m gonna do it today and put up a pic here of the final result.

The differences in behaviour between rm, mm, 3 and 4 gear are all on the site.
The main differences are in how it behaves under acceleration, cornering and in the air. (Balance and traction)

FWIW the "main" versions used are mm4 and rm3. Some use the other options, but not (afaik) that many.

And you don't add a gear, you take one large idler out and put two smaller ones in instead. No change to final ratio. But you do change the direction of rotation of the motor in relation to the wheels.
BTW in all configurations the motor runs "forwards" it's just the arrangement of the spur, motor and gearbox that change.

I did comment on another thread (same subject) a week or so back, have a search
