Is this single adapter all that is needed to make it work?
Thanks :-)

Thank you.
Very elegant solution.
Can you please explain what you mean by "Cut off 1 mm of the bottom part following the groove in the model"?


There is a line in the model, check it. You have to cut that part off (it is a ring). I do not exactly remember the reason but I am pretty sure there is a good one.

Yes I got it now :-)
Otherwise the cover will not fit and there bill be a gap between the bottom part and the cover of the motor.
This works great but I am looking for something in the middle (about 500 rpm) , can you give me an idea what I could model to make it work?

Tamiya sells some gearboxes with gear configurations, I think it would be really hard in this gearbox to get another ratio.

Hi There,

I Need more Torque on this, is it this mod will more power torque ?


No. This mod is for more speed, less torque

Thanks for your respon,

BTW is it possible change make more Power Torque on this Motor DC ?

Not a simple task. There is no more space for gears inside

Sad for hear that..

Probably i should buy new one DC Motor with High Torque..

Thanks Eried..
